That would be a new motor to me. I’m sure you got the model # 404 from your motor. Can’t search your model # here. Your motor looks to have the same flywheel as the model 401. If that is factory I would think that is an uncommon motor. Don’t want to know the exact last 4 numbers but in the hundreds or thousands what are they?
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
