This summer, I replaced the lower half on my Mercruiser Alpha one. Every time I went to put the boat on the water, I would check my gear lube level to make sure it was full. I would always need to add about 6 or 8 oz for it to register on the dipstick. I replaced the o-rings around the dipstick and drainhole to no avail. Finally I noticed oil in my bilge, which appears to be the gear lube. I keep my boat on a trailer with the trim up. Is there a seal that is the likely culprit? It ran perfectly all season, but it's making my bilge a mess.
