Spun prop hub: Replacement or buy new?

[Mwilson18]

I recently was having a speed issue on my bass boat (60hp outboard on 16’ fiberglass boat). Would only top out around 7 mph, so I took it down to my local marine shop. They got back to me, and told me that my prop was spun. I am familiar with the issue, and am debating on if I should have them replace the current prop hub (they outsource to another shop for prop repairs, will most likely take a while to fix), or just buy a new prop and replace it myself. Am I correct in saying that new props come with the hub built in and I could just swap out the old prop myself and my problem would be fixed?

So when you put motor in gear the boat would move ?-----Then at some point the motor would rev right up but boat would not go any faster ?----Motor is in good condition ?----How fast did the boat go for you last season ?

 

[Mwilson18]

Yes, boat would move gradually up until about half throttle. Then with throttle increase, there would be no difference in speed. Motor is in good condition, but this boat is new to me so I’ve never actually seen it at it’s full potential.

??____The question is ----Did the motor rev up suddenly , but the boat did not speed up.----You might have more issues.----What motor ?

It is smart to have two props, in case one fails during a boating trip. In your case, if the prop is good, have it rehubbed and buy a new modular hub prop as well. Get a spare prop hub too.
You need wrenches to change the prop as well, or just go for towing insurance.

Motor is an ‘89 mercury 60hp 2 stroke outboard. Motor will increase RPM’s smoothly, but would result with no speed increase.

Good to know, thank you Chris.

As current prop was not tached as currently loaded before having a spun hub won't know if was a good water performer or not ? Better check Merc's Prop Selector, dial all the needed data and check with which prop pitch comes up with and if close to your current prop model and pitch powering that 60 HP.

Happy Boating​
