I took the inner exhaust plate/s off yesterday and they looked to be o.k gaskets looked good with no visible signs of a leak on them. That will eliminate them as my problem of water getting into top cylinder. I am now waiting on my used cylinder head to see if that will hopefully fix the issue. Has anyone ever had a cracked cylinder head on an outboard that was letting the water into the cylinder ?? I have rebuilt this motor because it had thrown a rod and this cylinder head had been damaged with metal debri where the piston had gone up against it using the debri. The motor had ran fantastic for about 12 hours run time until about 1 week ago it lost a lot of power and won’t run high speed so that is when I suspected the cylinder head. I took a picture of it so someone that knows can look you may have to zoom in on pic.
Thanks for the help,
Joe
