So i de-carbed and he engine ran great. went out for a few hours. shut the engine off a few times to drift, and she would start right back up with no problem. Around 8pm i have a fish on, turn off the engine, I fight it back to the boat, release it. Turn engine on and all it makes is a humming sound. I havent heard that sound yet, and I start to freak. The nearest boat to me is 100 yards away, i blow my whistle a few times, get his attention and he comes to help. During my freindly tow back to port he asked me to check the starter to see if it was engaged, and it wasn't. It was stuck in the down position so i pryed it up and it engaged the flywheel. Now it won't go down becuase the engine seems to run under load. I guess I need a new starter huh?
