99 j115pleem. Today coming off plane boat did not want to go into neutral, was at about 2k rpm. Felt resistance in shifter handle. Immediately turned the engine off, shifted into neutral fine. Started back up got on plane and all was well coming off plane. Fished for an hour and it did the same thing coming off wot headed back to the ramp. I have the OMC manual but dont know much about engines and don't wanna havta deal with sync issues if it can be avoided.
