Ideas how, what caused, solutions? Not my boat, but buddies 05 230...
 
Did he drive it with one engine dead and potentially suck the water in through the exhaust?
 
No, both engines on whole time. Sucked up a rock, but never out of no wake mode, and then parked. Both engines have milky oil look...?
 
Milky oil= water in oil. I wouldn't drive it. Get towed back in.
 
What I have done with dirt bikes and one vehicle is buy a bunch of cheap oil, then do about 4 or 5 oil changes. Run the engines for 30sec after the first change for the oil to gather up water and then change, 2 min the second and so on. By #4 they are usually clean. More tedious with the yamaha as you have to suck out the oil and cant get it all. Hope this helps. Good luck. Cam.
 
I agree, don't run the engines as you will damage them. Get towed or leave the boat at a dock or moring ball if possible. Go back tomorrow and do 2-3 oil changes until oil is clean. Between oil changes pull the lanyard out and crank the engines to mix the oil that way you will know when the water is out. Fortunately for your friend it's fresh water.
 
If you have not run it since you noticed the milky oil or since you have been parked, pull the spark plugs on each engine, turn the engines over with the lanyard pulled to make sure no water is in the cylinders. Then you will want to drain and refill the oil a number of times. But need to find the source of water ingestion. The history of how you discovered it, how it was last serviced, and anything else that could be pertinent would help. Are you still on the water?
 
very unusual, definitely tow it back in and get the oil out, very strange both engines have the same problem.

For water to get in the engines the compartment would have to flood to the top of the manifold. That's a lot of water!

It may be worth investing in this to drain all the oil on each change, it would be messy the first time but may help save the engine/s and at $4k an engine it a lot of money.

good luck and keep us updated when he gets back in
 
Yeah....what they said....don't drive that boat! You need to figure out where the water came from. Also, I wouldn't leave the boat unattended in the water either....unless it is beached. How did water get into the engine compartment? Did you have a partial plug blow out which flooded the engine compartment (check the cleanout plugs and the connecting hose between the tray and the pump)
 
I'm thinking get it towed in very slowly and watch the engine compartment for water. You may have cracked a jet pump and flooded the engine compartment sending water down the dipsticks. Get it on a trailer and inspect the hull, pumps and cleanouts then do the oil changes. After all that take it out and run it good for a while to cook off any residual moisture.
 
Thanks for all the replies. Very helpful. The rock was pretty big, but got it out easily from the cleanout plugs. Boat was sitting when engine flooded. Bilge pump was off, which is why it filled up. Thinking maybe infamous scupper, since its still taking on water and pumping it out... Will check when on trailer... Goo g to do oil changes later today. Still hanging out for now... Thanks again.
 
Get the boat off the water while it is still easy. Your buddies boat is sinking right now. Hate to see this be another thread deleted for legal reasons.

Can't believe that tube is $160!
 
Actually, you don't need to flood all the way to the intake to get water in the oil on that motor. Just a bad seal on the oil cooler or on the charge end of the motor will do it.
 
Legal reasons?? Explain.

When someone wants to make an insurance claim and they posted that they were taking on water and stayed out they really do not want the insurance company to see that.
