Re: cheaper oil filter and plugs
170 - Any marine parts supplier or most auto parts dealers can either cross reference your existing plugs and filter (assuming they're correct) or do a look-up for the right items. In another post you mentioned going to Autozone to bench test a starter. They have always been able to provide me with a full selection. Otherwise use a Fram, STP, etc cross reference book or on-line info from their sites.
