A good ski buddy of mine just bought a 93 SS and told me he is having a problem with the throttle slipping. He says the boat runs great and accelerates with no issues, but once up to ski speed if he takes his hand off the throttle, the throttle lever will rotate back until the boat is doing about 15MPH. I have a 1990 Prostar and told him I have never had a issue with mine, Anyone experienced this before or have some suggestions?

Maybe he has too robust of a throttle return spring. If the throttle lever functions to allow the engine to accellerate in the first place then it should not be the cable. Something is causing the throttle to close. The return spring is about all that can do that.
