I have an early sloop with a W-58. The throttle lever creeps forward as I motor. I thought it must be a lack of friction at the brinicle but after purchasing a new linkage lever I find that is not the case. Any suggestions?
It sounds like the throttle cable was recently replaced. This is common with a new cable. Get a cable clamp and put it around the cable near the engine, not a hose clamp. Tighten it to firm but not too tight. Adjust until it feels right.
