I have a small leak on base gasket between head and mid section. I purchased the boat 4 years ago and it has been running fine. When I took cowling off I noticed the leak. Based on the orange coloured caulking or sealant at the leak point it appears that was a fix used at least four years ago. I'd prefer to just clean off the caulking and replace to get through the summer boating season then get the gasket replaced in the fall. Anyone have any idea what the orange caulking or sealant might be?
