I am unable to get my oil filter off on my 2001 188SD I/O Hurricane Deck Boat. The engine is a Merc V6 Alpha One. The filter is difficult to get to, which makes the problem more difficult. I have been using a socket type filter wrench with a 1/2 inch ratchet. I can't get good leverage, and the socket keeps slipping off the oil filter. I tried the strap type wrench and have now damaged the filter causing a leak. I am thinking of using the hammer and screwdriver technique next, but I know that I will really have a problem if that doesn't work. Any suggestions out there?
