    Lower RPM's on one engine

    Guy's took the boat out on Sunday and I noticed that one motor was down about 200 RPMs. I know the first thing to check is the boost so I'm going to pull all that apart and reseal it. But just to make sure how do you check for SC slippage? Is it as easy as putting a torque on the SC nut? If it was the clutch does 200 sound right to be low? (I'm sure it’s hard to say) What should it be for slippage? I'm thinking of doing the boost gages but if I don't have the IC block off where should I put the sender?

    I would look at the wear ring first.
