This has been an ongoing dilema with me, my wife and our local shop.
They checked the boat out before we bought it, and they said the engine checked out fine, 200psi on all cylinders, ran great, etc... but the transom seal needed to be replaced, so we left it for them to fix. They then winterized it, and it sat in our garage for a couple months.
So we take it out a couple weeks ago, I let it idle for a while, then brought it up to 25 mph for a while, then 35, then decided to give it full throttle, and while increasing the throttle, the engine quit, and it hydro locked. Got it home and figured it was an electrical issue from the engine quitting from not enough juice for the electric fuel pump. Had all electrical tested and it's fine. So after a couple days I decide to pull some spark plugs, and I found water in some of the cylinders, took it to the shop, they looked it over, did whatever they did at the shop, then I went for a test ride with the mechanic to see if we could re-create the problem, but the boat ran fine, didn't have any issues.
So I got the boat home, and checked the oil, and it was milky. I figured it was from when it got hydro locked and sat for a couple days the water crept down to the crank case. So I pumped 2.5 gallons of oil/water mix out, and replaced with 5 quarts of oil, and a new filter. I ran it on the muffs, the oil pressure is fine, and temp is fine, but the oil is still really milky.
I have new riser gaskets that I will replace now that it looks like it wasn't just water leaking down the cylinder wall.
Or could it still be some residual water? That's an expensive rinse if I have to change the oil again.
What's going on here??????
