I was out on the lake today and the boat was running great. on the way back to the marina I slowed the throttle briefly and when I went to get back on the throttle is was stuck. I did not force it down but it required much more pressure than usual. after this happened I was unable to get the boat to accelerate passed about half throttle even with the throttle fully pinned. I can also not get it to fast idle when not in gear. again it seems at about half the fast idle speed. any suggestions on this subject? I feel its related to where my throttle stuck and needed pressure to be moved. all ideas are appreciated!
