Good day,
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.
This will fix your problem at any engine speed. If you tighten it too much, you can’t even move the cable. Start loose and adjust until it feels right.
