i'm starting a new thread because i don't want to hyjack a thread (merc 470) can some explain more on using aftermarkets or ones that are manufactured wrong. as some people on this forum know i'm rebuilding my 470. i plan on using a different oil filter because they are to expensive to buy and i don't have a dealer near me i would have to travel long distance to get one. i heard someone mention that a 350 chev oil filter is the same. can someone enlighten me i want to put a correct filter on
