"Yesterday, was out for a run
"Yesterday, was out for a run in the boat, everything working perfectly, cruising at 3500 RPM @ 21 kts. Suddenly, the boat slowed way down, although revs stayed the same. Stopped the boat, slow reverse to clear any kelp etc. (nothing seen), then stated again. Revs go up easily, but now I get max 7 kts., and thick oil in my wake if the RPMs are over about 2500. Limped it back to the marina, had it hauled out & blocked. All looked normal (except for a small stream of water coming out of a small hole in the bottom of the exhaust bellows). Engine temp remained normal the whole time, oil pressure stayed normal, turbo spools up normally, no smoke in exhaust (just a slick of heavy, bubbly oil in my wake - think "Exxon Valdez" ...
First thought - is there an internal seal that could cause the clutch to slip, while spewing leg oil out into the water? Any other ideas?"
