Hi gang-
I took the X out for the first time this weekend. Over the spring, I took out the original Marine Power 350 FLV in order to have it freshened up over the course of a few months. My FIL had a pair of 383's in his garage from an abandoned project and offered to loan me one for the season. We accepted, and I installed the motor. This engine has a history. It was built in 2005, was installed in their project, and promptly blew-up shortly after installation. The engine builder admitted fault in their build and rebuilt it at no cost. It sat unused until this year. Since installing it I had run it for appx 1.5 hrs on the trailer, and it's obvious that it has a collapsed lifter. The builder was contacted, and recommended running it this weekend in the lake, at reduced power, to see if the lifter would free itself. I ran the X at the dock, then took it upriver to the lake. After about a mile @ 2500rpm. I stopped and opened the hatch to give a listen. Not only was the rap still there, but the bilge had oil in it. We pulled the boat, and I found that the fuel pump has a crack in the casting. There was around 3 quarts of mixed gas and oil in the bilge, and no obvious source of the oil leakage. The bilge was clean when I left the dock. The oil looks emulsified.
Now I'm at a crossroads. Should I have the 383 attended to, or pull it and have my 350FLV gone through and re-install it. I'm leaning towards the latter.
Thoughts/opinions?
