Hello. I took my boat out last week and docked it while we ate. When we got back to the boat to leave I could only put the throttle lever in forward but that boat was going in reverse. Even with substantial force to try and get the throttle level in the reverse position I could not do it. I inspected the engine and I could get the throttle gear to go forward with a pair of needle nose...but the throttle lever would still not go in reverse. Is this a shift cable issue? Any help would be appreciated!
