ok my first post of many to come , I have 87 4.3 merc ,alpha 1, oildyne/singer pump, yes as a new boater on unknown river slamed sand bar pretty hard lost all trim functions, dissassembled valves on the top on resivoir and sproket like mechinism was stuck freed it up and used a little penatrating oil on it , pump now runs like a champ, rehooked system up drained the oil and bought what I was told was the best oil for the system $12 a quartadded new oil and the trim seamed to be working , I ran it up and down about five times , pump started to whine ,I stopped checked resivior , and all the oil was all over the bilge area, as it is hard to tell where it is coming from either between the resivoir and the pump or the down hose connection is this a sign of a worse problem or is it simply o- ring on the top of resivoir,should there be enough back pressure in the resivoir to cause it to pump out the oil any help would be greatly appreciated
