I have been having an ongoing issue with my powerhead to exhaust adapter plate gaskets leaking water into the cowling. I have had the gaskets replaced 3 times, each time removing the powerhead. The first time it happened, I took it to a marine mechanic who discovered there was a cracked adapter plate and loose powerhead bolts. I had just bought the boat so had no idea. However, during the first outing there was no water leak. This tells me that even with a cracked plate this leak can be stopped. I ended up buying a new (used) plate that was in good shape. The mechanic agreed too. New gaskets were put on and it leaked again when I took it out. His response was that 3 of the 6 powerhead bolts were not OEM and didn't have the shoulder on them. I ordered new OEM bolts and torqued to spec when I once again replaced the gaskets. It is still leaking water. I am baffled. I know it must be possible to stop this leak. The only things I can thing of here are this: 1.) I did not put gasket sealer on all 4 surfaces. I put #2 Permatex sealer (recommended by mechanic) on one side of the gasket that mated with the plate and did same with the other gasket. I did not put sealer on the side of the gasket that lays on the cowling (bottom of adapter plate). The marine mechanic said they didn't think I would even need sealer at all. 2.) Maybe when I lowered the powerhead on the drive shaft it damaged the gasket but I don't think so bc it went on smoothly. 3.) I did not torque the adapter plate onto the powerhead itself. I tightened very hard though. I torqued the head bolts to the adapter plate. Still doesn't explain why lower gasket would leak. 4.) Maybe a warped powerhead or plate. Still doesn't explain how a guy who sold me a boat with a cracked plate could prevent the leak for one 3hour outing when I (who am following specs) can't prevent it for 5 mins. I am going to remove the powerhead 1 more time this weekend and redo. If this happens again I am going to have to get rid of this boat and motor and I really don't want to. Any thoughts on what this could be and how to make it work. Even ideas that would help it hold up for a few outings would be better than selling it. Here is a link to the gaskets: http://www.boats.net/parts/search/Me...PER/parts.html It is a 1995 Force 40 hp stroke motor. Thanks.
