WELL i went to the lake ran good at idle, ran down the cove came to a idle engine had a miss,cleared up after a few seconds took off again went to about 4500rpm engine was loosing power , pulled the dipstick creamy milkshake went back to the slip idled cleared up sounded strong again, came home and checked the innercooler and pours water down the intake. so i think i found my problem.

Damn man..You have bad luck this year.

man tell me, i havent put ten minutes on the boat since labor day weekend ready to sell it and do something different

just got done pressure checking the block and heads held 20#s for thirty minutes dont think any gaskets are bad, compression is still good. so i will change the oil 4 more times and try it again. if it milks again we are pulling it and tearing it down and starting over. ran with water in oil less than a 1000ft

From my own experience I know bearings dont take to well to milkshake even for a short bit of time. I feel your pain. Good luck!

Was the intake installed when you tested the block & heads? I had that hapeen to me years ago. At idle, no problem, clear oil, run down river, milkshake. Ended up being a leak at the intake to head connection at the front of the block. I was using FelPro blue intake gaskets that had the metal in them. Switched to Mr Gasket and the problem went away.

Also, as posted above, bearing was trashed very quickly. We tore it down after we got clean oil & Im glad I did.

yes intake was on, holds 12qts of oil 1qt of lucas, raised the level 1 inch on the stick, going to change it 3 more times and do the same thing take it to the lake and run it and see what happens, we boat in fresh water not salt,ran and sounded good when i put it on the trailer. i will hope for the best.

trust me there is a 3inch crack in the innercooler i know where the water was coming in.

Check for bent connecting rods now.
