I bought this old boat a few weeks ago. its in great shape for its age had a couple of wiring issues that turned out to be an easy fix. there's one problem i don't know if i should tackle myself or take to a mechanic. the idle throttle is broke when you lift it there is no resistance some part of the cable is broke. ive been told its probably just the pin that attaches the cable to the throttle but im also told you can get into a hornets nest when when you take the throttle assembly cover off. any advice is appreciated.
