I am cleaning up bilge area and want to remove the oil filter from the exhaust and mount on transom. How high above engine can i mount it? I am woried i may create an oil flow problem with the extra height, about 1 1/2' above it's stock position. Any recomendations or experiences?
Thanks in advance.

Height wont mater. hose length will mater.

I mounted mine on the transom just outside of the engine, did upgrade all the lines, fittings, adapters, and cooler..merc stuff is pretty much junk..

Mine is on the transom as well at about cylinder head height with -10 lines. It allows me to use an oversize Donaldson Filter #P550832, which keeps the oil super clean.

Thanks for the resopnses.

if you start over with new hoses&fittings go with -12.very little resistance to flow.
