Motor question

6 posts in this topic

Out on the lake yesterday afternoon and when we were leaving to go to another spot, I could not get the boat over 7 mph. When I pushed the throttle forward to go faster than that, the motor acted as if it was slipping and supplied no power to the prop. I could go slow, but nothing more than that. Glad I wasn't on Mille Lacs! It had acted like this before, but just when we were going into turns. Now it's all the time.

Dumb question of the day: Do boat motors have clutches? It's a 1990 Johnson 60.

Is the motor revving? Could be a spun hub in your prop.

Motor is revving. I'll pull the prop off tonight and see if I can see anything.

It could be one of the two items presented above...

I'd take a white paint stick / marker, take the prop nut and washer off, and draw a line from the Splined hub on the prop to the outside of the diameter of the prop (after the rubber hub), run it and see if everything is still lined up.

I'd say spun hub. If the clutch dog was bad, when it pops out of gear at a rate of speed, it'll feel like you hit the brakes as you fly forward. In your case it only happend on turns and then would grab and continue to go. Thats a spun hub.
