Mercury 3.3 hp outboard gone bad?
Help, please, I need help troubleshooting my outboard.
Bought used about a month ago, motored the dinghy around the harbor for about 30 min, then stored upright on the railing.
Mounted on the dinghy the other day and could not start the thing. Could not even pull the starter (like the motor was frozen). Next day using both hands I was able to pull the rope and turn the motor. Looks like I did not turn the fuel valve below the tank off a month ago, oops.
Pulled plug, sure thing it is wet from gas. Pull the motor through a few times without the plug, nothing sounds unusual. Plug back in and the motor starts, but..... sounds horrible. High pitched whine, like a bearing gone bad and the motor won't stay running.
Is it possible that I damaged the outboard by leaving the fuel shut-off open for a month? Is it possible I damaged it by pulling it through when it seemed stuck?
I don't have a "local" shop that I could take it to. I have tools, but never laid a wrench on an outboard(I can take a VW engine apart and put it back together blind folded).
