Re: Video of 1957 35 hp please help

That engine sounded and acted like it was knocking and seized at the end of the video. I could not tell for sure if it jumped out of gear or sneezed hard in the middle. If that engine has gone through that seizing routine more than once, I’d have a hard time believing it didn’t suffer some damage from that. Scored pistons seem likely. I sure hope that powerhead is getting enough water from the pump to keep it cool. I don’t see any smoke from the powerhead in the video, so maybe not an overheat? Possibly not enough oil in the mix as was also mentioned before? If that knock and then brief squeak as the engine came to a stop was crank bearings (yikes!) It’s going to need some attention before it gets run very much. I may be all wrong, but that video sounded like the engine slowed to a screeching halt due to excessive heat / friction and locked up.
