My 88 spl will push the boat at an idle and a little higher, but when you throttle the engine up it as if a clutch is slipping. the lower unit has recently been repaired, and there is no noise or grinding coming from the lower unit while moving or while putting it into gear. please let me pick your brain on what the trouble is.
If the motor revs up as you advance the throttle, but the boat does not go much faster, then you may have the hub slipping inside the prop. Install a known good prop of the same style and pitch to see if the boat now performs as it should.

Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Thanks, i was thinking that could be the problem, but when it revs up i see smoke or steam coming from the top of the midsection. Is there a possibility of the crankcase head assemblybeing bad
