5 oil changes and it was pretty clean. I did pull plugs at the end and two plugs near back did have a small bit of water on top of piston. Plugs came out dripping also which I am surprised as the engine idled very well through the oil changes. Think I should fog, dry plugs, then reinstall. Or just run it hard this weekend?

Run it but don't go to hard. Run for a while stop check your oil again keep an eye on temperatures etc and go from there.

We're the plugs still wet after you run it on the hose?. Just if they were that would concern me a bit

The two rear plugs were wet. Front two were dry. What do you think that means? Oil was even clean as I went through 5 changes where at the 3rd change it was already pretty clean. I did the proper break in. Are the rings not seated?

Are them 2 same plugs wet every time you take them out even after the engine has been ran?.

Only way water can get in cylinders if only 2 is cracked head or head gasket.

How long was it ran for as in after you tipped it over or did you tow it back? Did it start after tip over etc?

Water can get into cylinder also back through exhaust and into cylinder head as the exhaust is water cooled.

That kind of makes sense that the 2 rear plugs were wet, if the exhaust valves were open. The ski would sink rear first and the water would come in through the exhaust and start leaking through the exhaust the valves in the back end of the motor first. The water may have not made it up to the front cylinders.

It goes along with the reason that the owner manual instructions for flushing the motor on a garden hose connection is to start the motor before turning on the water and turn off the water before stopping the motor. If you do it in the wrong order, the water pressure from the garden hose will back up through the system and get into your cylinders.

How long did you run it on a hose connection before you pulled the plugs?

Cylinders 3 & 4 exhaust valves can't be open at the same time. What bothers me more if the ski has been ran and every time he pulls them 2 plugs are wet. Something more going on than just from being tipped over.

If it's only a small amount of water and ski has ran then it should be dry and that be the finish of it. But if they are continuing to be wet. Bigger problem

I understand your point but if the back of the motor had a lot of water pressure on it, water could still leak past a closed or nearly closed valve. The problem I had with the scenario is I don't understand why a head gasket would have blown or why 2 cylinders would have cracked from sinking event. Also, I don't understand how it could have idled smoothly, running on a garden hose connection if 2 cylinders are getting so much water that the plugs are soaked. I am surprised it would run at all with 2 water soaked spark plugs.

The rear plugs just had some water drops and maybe a dime size water puddle I could see on piston. I turned it over with all plugs out to see if anything came out. Nothing did while I also did the correct engine start then hose on off procedure. It actually starts right up and idles pretty smooth. I only ran it 1.5-2 minutes between changes. I am going to dry the plugs off and run it this weekend to see if they remain dry.

I have had good luck adding transmission fluid when you have water in the oil. The tranny fluid will help suck it up and get it all out.
