My next issue with the new (used) boat........
After taking the boat out four times, I've noticed that it seems to lose a lot of oil each trip. Like, maybe a quart or so every ten miles is my current estimate. There's no oil in the boat, but the rudders are covered, leading me to believe that it's coming out of the crankcase ventilation tube.
The engine's a 220 GPU. There are two ventilation tubes, one on the back of the crankcase, directly above the shaft it appears, and the other on the neck of the oil fill tube. It appears that the tube connected to the rear of the crankcase is the one that all the oil is coming from. There is also noticeble smoke (whispy, white smoke) that comes out of the rear tube. The exhaust does not smoke at all.
The engine runs strong, and if the runtime meter is to be believed, has over 530 hours on it. I run a six-blade warp drive, and the engine hits 2850+ rpm instantly. Oil pressure actually measures near 70 whenever the crankcase is full (10-12 quarts) and I'm running at around 2300 rpm, and settles down to around 50-55 after a while (probably after I've lost a quart or two of oil). I believe the oil pressure sensor is near the oil filter (front of the engine, on the accessory case).
My friend says it's probably my rings, and another guy I talked with said the engine may be gettin' worn out. I haven't measured compression yet on each cylinder, but will do that this week when I change the plugs.
Any ideas, other than buying stock in Shell?
