Yesterday I pulled the boat......replaced the water separator filter, oil & filter, plugs, and rebuilt the lo pressure fuel pump and replaced the lo pressure fuel filter. I dropped her back in for a test run. I could only get 5800 rpms and after about 15 minutes I started to see oil dripping on the inside transom. It looks like it still blowing oil/smoke out of the crankcase vent hose into the breather intake on the front of the engine. I checked the oil which was below the bottom mark on the dipstick. I added a quart and nursed it back to the slip.

What else can I check?? Any help is appreciated! thx
