A friend has gotten out of boating and has given me a few filters from his boat. He had a Merc HP500 and ran fram HP4 filters. My 2000 Merc 502 MAG has the same remote oil setup as his HP500 but came running the short filter from Merc (or fram ph6606). Will there be any problem running these filiters on my engine? Anyone with info, lets hear it. Thanks.
