I just replaced mine and still having issues, I got mine at a boat place, it was 300, on Amazon they were 129, the one I got has a plastic insert, I don't care for it much, but it is way cheaper if you have a spun hub again., I just bought an old Sea Ray with a 3.0 Mercury cruiser in it. After about an hour of running fine the boat would only run at a low speed, when I would try to accelerate it would sound like something slipped and it would stop moving forward, then I would go slow no problem, try to accelerate, done the same thing. I replaced the Hub and prop, took it out and it was doing good and after an hour or so, done the same thing again, it surely didn't spin the new hub or did it, is something slipping after warming up, I don't know a lot about boats, but I'm mechanically inclined and this does not make any sense. anyone have and good information.
