I have a 2005 MerCruiser 305 with a gear lube monitor mounted on the engine that I have to keep filling because it is leaking from the top area and it don’t show any cracks. just looking for any way to stop this so I don’t have any oil in the bilge.lhad the outdrive pressure tested and checked out ok. Seems to be over flowing somehow even though i don’t fill past the fill line.
