Just another note for you guys to try.
Instead of placing the strap type wrench at the end of the filter where the notches are, place it as close to the gasket end of the filter as possible. Less chance of crushing and twisting the filter and making more of a mess. I oil the o-ring up on the new filter, and go hand tight with a rag. Anything more than that your asking for problems! You're not torquing down cylinder heads! I think alot of the problem with boats is being a remote filter, its very accessible and guys get carried away tightening them. On cars, usually you can't access the filter as well, and tend not to be overtightened.
