Ok guys the motor is a 1981 Merc 165 hp inline 6 cyl with San Juan FWC. and a 2 barrel rochester carb.
The crankcase is loading up with gas and I don't understand where it could be coming from? I JUST installed a new (mechanical) fuel pump AND had the carb professionally rebuilt this summer! How else can gas get in there?
In September when I installed the new fuel pump I gave it a fresh oil change and took the boat out for maybe an hour long ride spending about 20 mins of that time on the plane. Now the dipstick shows almost 2 liters above the mark! It almost seems as if the level is rising as it sits in the driveway but I'm not sure? Any ideas? Thanks.

Like, is it filling up when the engine is not running, or both, when did you notice it, have you used the boat since, did you check the oil level immediately after a trip? Have you drained the oil, how, from the bottom of the engine or using a oil suction pump. Basically the more information you give, the more accurately we can help you... The FWC system, does it do just the engine or engine AND manifold?
