Probably a result of improper winterization, unit froze. Watercraft will run fine out of the water without land water connected to the machine, but will run only for about 5 minutes once launched, water/gas mixture then blows up through the carboraters. Once torn down, there appeared to be water in the back crank cavity only. In addition, the front cylinder and piston are good, the back cylinder and piston are scorred. The head gasket appears to be good.

How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

The water may be entering the crankcase from a blown head gasket, a cracked cylinder head or damaged exhaust manifolds. Have a marine technician make sure this is the cause of your problem. Depending on the extent of the damage, the engine may need rebuilding or replacing.
Most four-stroke engines use a crankcase that contains the engine`s lubricating oil, as either a wet sump system or the less common dry sump system. Unlike a two-stroke (crankcase-compression) engine, the crankcase in a four-stroke engine is not used for the fuel/air mixture.
When too much water is introduced into your motor`s cylinders it results in hydrostatic lock, or “hydrolock,” an engine state in which the pistons freeze and the engine stalls. Water does not compress like air which is what causes the sudden stop.
The water in your car`s vehicle circulates around the engine, and helps to keep it cool. With no water in the system, your car runs the risk of rapidly overheating, which in turn can cause engine damage.
Diesel engines produce water vapor during fuel combustion. Under adverse operating conditions this water vapor, and the moisture from humid combustion air, may condense in the crankcase and mix with the oil. Large quantities of water sometimes enter the crankcase from leaking cooling systems.
A cracked or blown gasket is the most common cause of this issue. Apart from this, cracks on the oil cooler, leaky gasket heads, damaged engine block can also cause coolant to leak into oil. Overheating of the engine often causes damage to the gasket and engine block, which then leads to coolant leaks.
If the engine is producing blow-by gases faster than the PCV system can dispose of them, an increasing surplus becomes trapped in the crankcase, causing excess pressure and, inevitably, oil leaks. Even the most carefully sealed gaskets leak when confronted by rising internal crankcase pressure.
Engine sludge develops on and around your vehicle`s motor when oil begins to break down and collects on the engine. When engine sludge is present, oil is not able to properly lubricate the moving parts of your vehicle`s motor.
Beyond the unknown circumstances, driving through moving water that`s at least four inches deep or standing water that`s six inches deep can seriously damage your car`s internal parts: Due to near-instant cooling, the brake rotors may warp. The car`s power steering may suddenly die. Electrical components may short.
Is A Hydrolocked Engine Repairable? Yes, you can repair an engine that suffers from a hydrostatic lock. Less severe hydrolocking will only require minimal effort to fix. However, severe damage will involve a lot of time and effort to inspect and replace damaged parts.
If the engine is cold, or there is an excess amount of cooling around the cylinder, the fuel oil will condense and have a higher chance to end up in the crankcase. Another way that the fuel oil can end up in the crankcase is because there is too much wear on the piston compression rings.
Blow-by, also referred to as crankcase pressure, occurs during the combustion process when burned gases leak past the piston rings and into the crankcase. The rotation and speed of the rotating assembly, which also causes windage, contributes to crankcase pressure, as well.
You`re Not Driving Enough

Yes, the oil cap makes an airtight seal, but changes in ambient temperature and humidity attract moisture from the air to the metal in the engine. This happens in all vehicles, and it`s not usually a problem, as the moisture evaporates when your engine is up to running temperatures.

engine oil (crankcase oil, motor oil) – oil carried in the crankcase, sump, or oil pan of a reciprocating internal combustion engine to lubricate all major engine parts; also used in reciprocating compressors and in steam engines of crankcase design.
A crankcase explosion is caused by ignition of oil mist, itself created by the presence of a hot spot, which led to the evaporation of lubricating oil and its condensation into an oil mist. Its consequences can be severe, including death and serious injury to personnel and extensive damage to the engine.
One of the easiest ways to fix the leak yourself is to use a stop leak additive or high mileage oil blend. Such products can soften and condition your car`s rubber seals to stop and prevent further automotive leaks. It may take up to a few hundred miles of driving before the leak is completely sealed.
They keep the oil, which is tossed by the rotating crankshaft, from leaking outside of the crankcase. If they fail, they cause leaks which can make a mess and can put the engine at risk of serious damage if they are not dealt with quickly.
Common signs include oil leaks, excessively high idle, and a decrease in engine performance, power, and acceleration.
Sludge from municipalities (often called sewage sludge) is a byproduct of wastewater treatment. It is normally a mix of organic matter from human waste, food waste particles, microorganisms, trace chemicals and inorganic solids from products and medicine we use, together with water bound to these materials.
The percentage of water in the hydraulic oil should basically not exceed 0.12%. The range of 0.10 to 0.12 % is already critical. Here, at least oil-care measures should be taken. Above a concentration of 0.12%, however, it is essential to change the oil because of too much water in the oil.
Having a small (i.e. minute) amount of water in the gas tank is normal. All petroleum is going to contain a small amount of dissolved water in its composition. For E10 fuels, that`s typically up to 0.5% by volume.
Even water getting in the tailpipe can cause serious damage. The catalytic converter can be ruined — a $1,000 repair — and it may not be noticed until failing an emissions test.
After you park your car and the engine starts to cool down, the water vapour cools down to the water, dripping from the car`s exhaust pipe. This is quite normal and not a severe problem to be worried about.

I have Detroit 60 series installed on a launch. Recently the Starboard unit suffers a catastrophic failure and piston No2 came out of the block, making a big hole. This engines are using heat exchangers, and sea water cooled Charge Air Coolers and sea water self priming raw water pump. We contact the local dealer an the veredict was a “Massive salt water ingestion” that caused an Hydraulic lock and damaged cyls 6 and 2. They say that the water came from the deck covers, but there is no way for that to happen, I think they dont want to honor any warranty, because we suspect that the water came from the Charge Air Cooler. I want to know if the CAC can cause that type of failures and if anyone had a similar problem. The engine cost is about 66K and only had 2300 hours.
ANSWER : I would have to say that a sleeve got pitted or lost an oring or the CAC sprung a leak. I believe you are correct in your assumption that the water did not enter the unit in the manner they are saying. The only real way to tell is a complete tear down and someone is going to have to pay. They are also a high maintenance item and someone is going to say that the preventive maintenance was not done.

I have a volvo penta md7a marine diesel engine fitted in my sailing boat. Recently, I changed the bottom sea **** which was almost blocked. Apparently the new sea **** is working well as it should. But this week with no apparent reason and without use of engine, I noticed that the cooling system water cup (the recipient which connects with the sea **** hose and the water pump hose) is empty and it Im not able to keep it full like it was before.The water vanishes every time I tried to fill it up in order to keep the water running throught the system. However the waterpump seems to be working. But almost no water is coming out of the exhaustor, of course, just a few drops once in a while. What might be going on ?? Thanks.
ANSWER : I don’t have a picture of the installation, but I can imagine a water filter above the water line with an improperly fitted cover and an air leak that lets the seawater drain out – losing the prime. Old Swampy in New Hampshire

I need to hook up 3/4 cpvc water supply line to water meter
ANSWER : I went to Home Depot for the same reason.Ended up getting a brass fitting with a cpvc insert that excepted the cpvc pipe to be glued into brass fitting once it was screwed in place.Came out about a foot then used a coupler to join both cpvc pipes so in the future I can replace meter without cutting pipe.Im not a plummer just a home owner who cant afford one so I dont know if I did it right but it works.

We have a 1994 HiLo FunLight camp trailer. The water pump does not come on when attempting to use the water.
The tank is full of water, the battery is fully charged, the trailer is connected to power. Any suggestions? Where is the fuse located? Where is the SureFlo Water Pump located in this trailer?
Thank you very much. Chuck Stafford
ANSWER : THi-Lo Trailer500 South Main StreetPO BOX 577Bellville, OH 44813Local: 419-886-0066This is a link that may or may not help you:. If there is a fuse or a breaker for the pump, it would more than likely be on the DC panel. The pump could be located in a variety of different places but would probably be under a sink, around or on top of water tank, or in storage under the bed, access being either by removing matteress and a panel hidden by matress or, by removing a drawer in the base of the bunks lower structure. You probably have a pressure valve in the line somewhere near your water inlet connection, you may want to check that and, the pump might be in thta area also.
