tohatsu 25hp running hot

[will941s]

My 1989 25 horse tohatsu ran hot then after that it had a tough time idling. I removed the head and noticed a broken ring around the head gasket. The pistons and the cylinder walls look good and there are no obstructions in the water passages. Would a new head gasket and water pump fix the problem?

It should put the engine back in good enough condition to find out if there is anything else wrong.

Thanks very much for the reply. Since I have it exhaust plate and the head off the engine still is there anything else that I should check for before I put Everything back together? I just installed a new water pump just before I took everything apart. I hope all the probelems are solved. Anymore tips would be greatly appreciated. Thanks.

Just take a very close look at the interior sevvices of the block. Look for cracks, rough spots, etc.
