Since water got in the motor in the 1st place from a failure, what good does changing the oil repeatedly do? The issue is still there.

Well Iam hoping the water entering the motor was due to the leaking manifolds/risers. I will be replacing the manifolds/riser and hopeing that is the last of the water issue.
Well i'll see what happeneds this summer.... :cool:

Well, I stated in my post that the original water ingestion issue needs to be resolved first.

Sorry guys, it looks to me you just wasted your time telling him what to do. Sounds like new exhaust system and things will be fine:rolleyes: I bet the rings are stuck, plunger in lfters stuck, nice bearings oil with water turning to steam, maybe a sticking valve at 3000rpms or more, cylinder walls nice and rust pitted. Hydro-locking of that cylinder having an effect on the rod bearing. I have seen 20 min. run time on an engine with a rust hole under a intake valve seat sucking water wear a rod journal out of round .003. If he runs that thing in that condition the next post will be about a blown engine.

No one is wasting there time. I thank everyone for there info and help, but at this time I can not put a new motor in the boat. I understand everything you posted is your opinion on the condition of my motor but I will say i think your wrong. For what it is the motor runs great and I know it dosn't have rust pitted cylinder walls, rings stuck, bad lifters. I will say Iam not 100% sure on the condition of the bearings. :grinser010:

Talk about bad mojo, man, I just pulled the valve covers off my starboard engine.... found milky oil and some rust on the guideplates.

Pulled the intake and heads to determine where the water was coming from, and it turns out that the intake gaskets were leaking water into the lifter valley.

Nice!

:angry-smiley-038:

I bet its the intake !!

Replaced old intake with new intake and gaskets.
So I'll see what happeneds when I run it! :eek:

P.S. I 'll let you know about your block.

My old motor used to get water inside after just a few minutes of run time right after I bought it. After countless tear downs and checks finding nothing wrong, turned out my intake gaskets weren't tight. I used to do the normal 3 rounds on the torque pattern and be done. Even after the 3 rd time around, the 1st bolt in the sequence was finger tight do the gasket being compressed each round. I now go around as many times as it takes till the 1st bolt still has torque to it.
That was on my blower intake, the stock Merc intake was never a problem. Just something to keep in mind on your intake install. Good luck.

This is true. I just installed a new intake on my motor and took countless rounds of tighting till they all were tight. After firing it up and warming it up i'll go back and recheck.
