The causes of water in the oil I saw were: rain water through the carb (check to make sure water cannot get into carb when boat is stored.) bad exhaust risers (snail) (I boat on salt water so happens alot) bad head gasket (usually on SBC only) bad intake gasket intake valve not opening, causing exhaust to suck water in from manifold while. I agree - water CAN ruin your engine - we had lots of water in our system, including our oil (most likely entered due to continuous cranking when trying to turn the engine over), and I think we have a slight leak in our head gasket (oil analysis showed small amounts of coolant in the oil too) due to overpressure from a partial hydraulic lock So I took my boat out one day about 1 month before I was going to take it to the keys for a week, boat ran great to whole time. I got home and decided to change the oil. Took out dipstick and engine was loaded with water, oil was like milk, needless to say I knew right away big issue. I ran to store and got like 3 gallons of oil and started. Water in outboard lower end oil, what to do? As the title says, I found water in my lower end oil. Did a DIY pressure test at 10-12 lbs and found air and oil being pushed out around the prop shaft seal. How should I proceed? Can I just change the seal and go or do I need to pull the whole carrier.. . Oil with too much water in it is bad because it causes greater friction, builds up heat and can cause premature wear and tear on your engine. If it is too bad it can ruin your engine
Motor oil contaminated with water can damage your auto's engine. Luckily, water and oil naturally separate. When contained together, water settles to the bottom while oil rests on top. Dirty motor oil may settle to the bottom because of the increased weight of metal particles Hi, Further to a recent post were i had to remove the engine for an oil pan leak, after re installing the motor, i have been out several times since without any problem, however last week i had been out around 2 hours on the gulf running around 27-32 mph (GPS) when the alarm sounded to let me know engine was running hot, So i quickly stopped and lifted the hatch to see what the problem was.
If water is mixing with the oil in a V-style engine that has intake manifolds sealed to the block, then the intake manifold water jacket gasket might be leaking into the inside of the engine. Such leaks occur when bacteria builds up in the antifreeze or coolant solution Sea water in oil etc So towed in (5Hrs) and had the boat hauled out. Engine removed and torn down for failure mode investigation. Head gasket blown between #5 & #7 cylinders, not across a water passage. Source of sea water - corroded exhaust manifold, when the engine was shut off water drained in the cylinder 3. Do I Need to Change My Boat Oil Every Year? Experts recommend changing the oil for a gas boat engine once a year or every 100 hours. Changing your oil extends the life of your engine, so you may want to change it more often than what the manufacturer recommends. If you have a diesel engine, change the oil every 50 hours or less. 4
IMPORTANT: A check for water intrusion should be performed on all new Marine Engines with thru transom and Thru Hull Exhaust Systems. Two methods can be used to check for water in the Marine Exhaust Manifolds.The simplest and least time‑consuming way is the exhaust elbow removal method. With this method, however, it is difficult to accurately determine the amount of water in the manifolds I found from my experience that as long as the motor doesn't sit for very long with the water in the oil in the bottom of the crankcase the crankshaft won't lock up to the connecting rods that's where the problem comes on by draining out the Milky.. The most immediate signs of engine damage from water exposure will likely be found in the engine oil and transmission fluid. By just checking the fluids with a dipstick you can see if there has been exposure. Water will make the transmission fluid look milky in consistency. Water in the oil pan will also dilute the engine oil as well In a boat engine, water that exits the engine at the thermostat housing is diverted to the exhaust manifolds or headers, and eventually enters the exhaust stream after the tailpipes bend downward and out toward the transom exhaust outlets.That matters because it affects cam choice in a high-performance marine engine
Assume new filter elements are doing their job. Diesel engines, and gasoline engines running far offshore, should have two water separator/filters per engine. But don't put the same type of element in both filters, or worse, put the finer element in the first filter. Doing so makes that filter do all the work, with little to no benefit from the. How to Change Boat Engine OilCaptain Cody shows how to change boat engine oil with the boat on the water. This is done by using a manual vacuum fluid extract..
Using the correct marine fuel and oil in any boat's engine—outboard, sterndrive or inboard—will ensure many seasons of reliable performance. For guidance on fuel and oil requirements for your marine engine, turn first to the owner's manual (if you don't have that manual it may be available online or you can order a copy from a dealer).. Water can get into the oil two ways. You generally don't have to worry about one of the ways if you drive your car enough to burn off the water during normal driving. This drives off the moisture that simply comes from your engine breathing when it is not being used (cold air enters a hot engine and water condenses) and from combustion byproducts Your used engine oil can serve as an indicator of engine health. For example, a milky color indicates that water has entered the crankcase, and the presence of metal particles may indicate excessive wear. When in doubt, consider having your oil analyzed. Periodic oil analysis can give you a very good idea of engine health To give that oil a chance to do its job, let the warm up before heading out on the water. The most common cold-weather outboard problem is something I call duck hunter's freeze-up, which occurs when a hunter tilts up the outboard to keep it out of marsh muck or to pull a skiff ashore
For full extended winter storage, after completely draining the cooling system, Mercury MerCruiser requires the use of propylene glycol antifreeze (with a rust inhibitor for marine engines) in the seawater section of the cooling system. The fuel system must have fuel stabilizer added and the system must be fogged with 2-cycle oil . Compare Prices Online And Save Today Before you start tearing down the motor looking for cracks in the cylinder head or blown gaskets, you might want to check the thermostat. Believe it or not, a faulty thermostat can cause water buildup in an outboard's engine oil. If you find water mixed in with the oil, test the thermostat first before you panic
Water in the engine - Water can get into your oil sump in two ways: Water in car - Water condensation in cold air or combustion gases: this phenomenon is extremely rare and only occurs at specific temperatures. Water in the oil - Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is. You put your boat away for the winter by doing all the right things: changed the oil, winterized the water system and engine, and emptied the boat of all extraneous gear for the offseason. So you might think there's not much to do come spring except take the cover off, fire up the engine, and head out to the wild blue yonder. Hold on! Not so fast Ideally, drain your oil right before the boat is hauled, refill, then run the engine for a minute or two to make sure everything is coated with clean oil. When you start the boat in the spring, remember that all of the oil has drained into the pan and let the engine idle for a minute or two to recirculate everything Check for oil pressure if you have a dash gauge, then go to the engine and look for water running from the exhaust or telltale. If you see none, stop the engine and recheck your hose connections. Once water is flowing, run just above an idle speed. Check your dash gauges for operation. In the engine area, be careful and stay away from the engine Water pump seal failure and weep-hole blockage; The chain reaction then gains new life; as the detergents and dispersants come in with the new engine oil. This now begins to mobilize the sludge and deposits. Then, within minutes after an oil and filter change, the new filter can become plugged again..
Engine water, known as coolant, or oil from a badly leaking head gasket can fill a cylinder beyond the combustion chamber capacity. The consequences are virtually the same, except engine oil won't corrode like water does. In a small sampling, fuel is one of the liquids engine hydrolock can be caused by. If a carburetor jet is stuck or a fuel. The motor oil flows through a heat exchanger, where the heat is passed to a central engine room cooling loop, before the heat is rejected to the ocean. Jacket water. Heat generated an engine's cylinders is transferred to a jacket water cooling system through the cylinder wall. In addition to cooling the cylinder walls, jacket water is often. The boat in the ABYC video uses a raw water system with a heat exchanger, connected to a freshwater loop that cools the engine. This is the most common type used in recreational marine diesels. Typical problems happen when there is a blockage of the flow in the raw water side of the system reentering the engine when the boat is placed back in the water and docked, tip the engine up, keeping it out of the water when not in use. Motor flushers may be purchased for around $4.00 at area marinas, boat retail outlets, hardware stores and local sporting goods stores. They may also be purchased online
How much is too much? An ounce of spilled oil can pollute 120,000 gallons of drinking water and a single pint can cover an entire acre of water! Smart boaters have a convenient way to keep engine oil and fuel out of the water. Oil-absorbent sheets, pads, donuts, socks and bibs are designed for use in bilges, under engines, and when fueling Hi-Performance Engine Oil Cooler, 3 Diameter, 16 Overall Length, 3/4 NPT Oil Connections, 1 NPT Water Connection. Designed for engines making 450 to 750 horsepower. These units have seventy-six 1/4 seamless tubes - over double that of a 2 cooler. The cooler incorporates cast end caps, NO cheap press-formed caps are used The engine alignment to the propeller shaft should be checked in the Spring when the boat is placed back in the water, and the mast stepped, and the rigging tuned. Controls and Linkage Check the security of control connections to the engine and transmission
What we can do is find a good place in the fuel line close to the engine, and disconnect the fuel line from the boat to the engine. Makes sure that the boat has the bow lifted into the air. Any water or dirt that is in the tank, will be shifted to the back of the tank and pulled out of the pickup tube first Mer cruiser dipstick tubes are also Oil Withdraw tubes. You can suck all the oil out of the engine through the dipstick tube. This requires the use of either a small hand pump (part 802899A1 Oil Pump which can be purchased online or you can buy a more expensive Oil Changer Pump/Bucket Assembly from a marine supply store (about $160.00 and up) Engine oil is thick to provide a good coat, coolant is thin to maximize flow and dissipate heat. Oil is chemically manufactured to play well with internal engine parts, the chemicals in antifreeze make it naturally harsh on internal engine components such as bearings, causing wear and damage over time if repeatedly exposed I added 6.6 gallons of boat tank fuel to my 20 gallon car tank which had about 9 gallons already. Symptoms soon arriving after 2 startups and maybe 6 miles defined there was water in the boat fuel. I have added (2) 12 oz Iso-Heet and started OK then became rough running, water and black carbon on my garage floor under exhaust pipes Oil consumption is like water evaporating on a hot day. Just like the heat of the sun lifts water molecules out of a container of water and into the air, high engine heat can lift the light, unstable molecules out of oil, causing the oil level to drop. The evaporated oil exits the engine through the crankcase ventilation system
Factors causing black motor oil. Heat cycles naturally darken motor oil. During your drive to work in the morning, your engine reaches normal operating temperature (typically 195ºF-220ºF [90ºC-104ºC]), heating the motor oil. Then the oil cools while your car sits in the parking lot I used this on 2 boats both being 2 strokes. 1 is a bass boat with a 150 merc. Other is a offshore boat with twin 175 mercs. In both cases I started with 80:1 mix being new to Ams-oil. After intensive research I went for the 100:1 mix. Both boats smoke much less. They dont load up like before idling and trolling Step 4: Inspect the drained oil and your oil plugs. This step is key, but often gets overlooked. The oil should be dark and not milky. If yours is milky, it means you have water in your oil, and you'll need to take your motor to a marine mechanic
Any water in the oil is a sign of a leak in its respective heat exchanger, and you will want to eliminate the leak and replace the oil before the engine is run. Unless you are really good with engines you may want to have the engine professionally checked if you found water in the oil, as a little water here can do a lot of damage in a short time Most marine engines today use a more sophisticated indirect cooling system, with the engine cooled by a fresh water and anti-freeze mix, just as it is in a car. The only difference is that instead of using air flowing through a radiator to cool the coolant, a marine engine uses raw water flowing through a heat exchanger 1. Not Enough Oil in the Engine. Even if the correct amount of lubricant has been added during an oil change, the oil may be unduly consumed due to evaporation, burning caused by worn piston rings, and leaks through the seals or oil plug. Oil consumption increases as the engine ages, so checking the oil level and topping up may be a simple.
If you live up nort', you know the drill: Give the boat a final cleaning, take everything out, fog the engine, remove the batteries, drain and run pink antifreeze through all the water systems, create a PVC-pipe skeleton inside the boat and cocoon your baby in shrinkwrap until the spring metamorphosis Do not put your boat in storage with dirty oil. After just a few hours of use your engines oil is dirty and contaminated, with water, acids, unburned gas and dirt. Dirty oil can damage your engine if left in over the winter months. If you do not change the oil it will start to corrode the metal surfaces of the engine and damage bearings. It seems that salt water getting into marine turbochargers from poorly designed exhaust systems is a weekly on-going issue in the forums at boatdiesel.com. It also seems that the vast majority of Cummins techs, independent mechanics, and boat owners out there have no clue as to what the symptoms are when that occurs
Adding a fuel-water separator is a good idea, too, as this filters debris and water out of a boat fuel line, preventing it from reaching an engine with potential costly results, adds Rogers Install additional water separating fuel filters in your boat and keep spare filters on-hand. Use a fuel stabilizer along with fresh fuel when your boat is stored (follow the procedure noted in your owner's manual to ensure proper storage) If the oil still looks milky after the engine warms up, the water may have leaked into the oil from a defective water pump or cylinder head gasket, or a damaged cylinder head. Antifreeze can also. Directly cooled units have raw water (the water the boat floats in) pumped around the engine. Indirectly cooled engines are a more complex, with a closed cooling system somewhat like that of a car. However, in place of the radiator there's a heat exchanger in which the coolant in the sealed part of the system is cooled by raw water blast, and let the hose's water pressure do the work. Let the water run for 15 minutes to ensure it fully circulates through the entire cooling system several times. If your boat's out of the water, like on a trailer or a lift, the fresh water will also trickle down and adequately clean the water pump and the lower unit's cooling water.
Save money & the environment. 20-25% discount for preferred customers Engine load. The typical loads placed on your outboard are much heavier than on your automobile, having to overcome a much greater amount of drag to create performance. This means your outboard is working much harder than your automobile's engine. Yamalube 4M and 2M marine engine oils contain specific anti-wear additives to account for this A maintenance item you can perform is flushing the engine with fresh water after each outing. Many engines have special ports for attaching a garden hose to rinse the internal cooling-water passages without running the engine. If you keep your boat on a trailer, you can use a flushing attachment known as ear muffs Oil Analysis for better control. Industrial and Marine Engine Oil Analysis. Volvo Penta oil analysis delivers a comprehensive diagnosis of the engine's condition. Oil Analysis provides information such as water and fuel content, viscosity, dirt and the amount of metal particulates in the oil from component wear
Most hydraulics aboard boats use a pump to pressurize the fluid, usually oil, in a closed system that typically includes a reservoir, oil lines, pistons, rods, and other parts. Since the hydraulic fluid is incompressible, the pressure created by the pump at one end of the system is maintained throughout the rest of the system, even if it is large Oil keeps our cars, lawnmowers, and many other machines running smoothly. However, during normal use, impurities such as dirt, metal scrapings, water, or chemicals, can get mixed in with the oil, so that in time, the oil no longer performs well. Eventually, this used oil must be replaced with virgin or re-refined oil to do the job correctly Lucas Extreme Duty Marine Semi Synthetic 20W-50 Engine Oil is designed for use in high performance boats requiring the ultimate protection. Marine SAE 15W-40 CK-4 Oil Lucas Oil Marine SAE 15W-40 CK-4 Oil is blended with premium base oils and Lucas additives
Flushing a boat motor by running it out of water is a routine maintenance task. Running the engine without a water source for any length of time will cause damage, so you'll need to attach a hose to the motor's water intakes. Some newer motors have built-in attachments that accept a hose nozzle I WANT to use what is recommended by the manufacturer. My issue is the discrepancy between the boat manufacture and the engine manufacturer. The Mastercraft website says to use SAE 15W40 SJ/oil, but my Ilmor manual states to use Pennzoil 5w-30 synthetic. Thanks for pointing me to Amazon for the oil and filter Engine oil and filters must be changed before storage because of the acids that develop in the oil, which can attack bearings. Also, since marine engines run cooler than automotive engines, moisture/condensation stays in the oil instead of evaporating out of the oil The raw water will be used with your Engine Oil and Power Steering Coolers as they will not be part of the closed circulating system. From Here the raw water will be passed into the heat exchanger tank and be pumped through many small tubes where it will exchange heat from the circulating systems water For those who have not seen an oil analysis report, this 11 page one includes analysis of generator oil, both engines and the lube from both gear reduction units.This report is pretty typical and clearly shows why you may need to hire a qualified diesel mechanic to help interpret.: So you may save the cost and time of an oil analysis by simply pulling the dipstick and taking a look How To Start an Outboard Boat Engine Out Of Water. Starting an outboard boat engine out of the water can be done by using a tool called a Moeller Flushrite Boat Motor Flusher. This tool is designed to look like ear muffs so that it can firmly attach itself to the inlet vents on the motor. The inlet vent is what sucks the water in to cool off.
