head temp really doesn't mean anything, especially on a marine engine where the entire lake is your radiator. oil pump is a fairly easy fix to try. we've had motors where the clearance was higher than we'd have like and will put a high volume pump in there. the theory being that its leaking more oil pressure out of the big bearing clearances than we'd like, so the extra volume will help keep the pressure up. i'd consider it a patch until you can fix it correctly.
an oil temp gauge would be a good idea too.
