I bought my boat used late last summer. I'm changing the oil and the oil filter is stuck. I've tried a strap wrench and 2 or 3 other filter wrenches and its still there with some dents in it. I even tried heating it up with a hair dryer on high for 15min (a tip I read) with no luck. I'm thinking about leaving it and just changing the oil...let the shop figure out how to get it off in the fall. I've already decided this is the last time I'm fooling with changing the oil in it anyway. Do you think it will hurt to just leave the filter the way it is until the fall?
