Default Dock Line in Prop and Loss of Power

Hello,

I ran over a thick line that got caught in my prop and shut down my outboard engine immediately . I removed the line, and the engine started. However, when I shifted into gear (forward or reverse) there was a slight grinding noise before gear engagement that was not there before the incident. The boat operates fine, but I have noticed two things other than the slight grinding noise. First, when I put it into forward the bow did not rise immediately out of the water as it did previously. There was noticeable drop in power. I could only reach about 25 mph at full throttle even though the boat is rated for over 40. I do not hear anything else. Did I break the internal hub? Did I do some other damage that requires me to bring the boat in for repair? Any thoughts on what I am looking at for repairs? Thanks.

You goofed something up, pull the prop and have it scanned. Then have somone check that your drive shaft is still true.

That rope dammaged something but, everything can be fixed.

Possibly the prop is now out of shape or the prop shaft is bent and you are getting poor drive from that. Are your rpms at WOT the same or have they dropped?

Spun prop hub? Make a mark on the prop and hub and run it in the water. If the lines don't match after, the hub is spun.

You should have got a tow. I’d take it to pro

Are RPM limited or can the engine rev high when resulting in low boat speed?

Thanks for all the replies. All of the feedback is helpful and tied to the prop. Any thoughts on the grinding noise I hear when putting the boat into forward or reverse?

you might still have some pieces of rope caught behind the prop that is putting pressure on the output shaft. Your prop or shaft might be bent. I would take it and have it checked out, continuing to run it as is may cause more damage.

Be thankful it wasn't an extension cord.

Does the prop look out of shape or damaged? It would pay to check for a bent prop shaft as well. The grinding could be internal gear damage so I would pop out the gearbox oil drain screw and check on the magnet for bits of metal.

Have you pulled the prop yet? You can check for a bent shaft yourself. A clamp and a straight edge home rig will be indicative , but not give you the runout.

My guess what your hearing may have always been there your just listening closer since the incident. I've had a crab trap line choke off my motor (stop it) before although there was no damage. Sounds like it could be a spun prop if you don't see any damage to prop. I would try what louiefl suggests.
