Noise Alpha One Gen II

[DaJones]

I am new to boating, I have a 94 Searay 200br with an Alpha One 5.0LX with 400 hours on it. I have noise when making hard turns. I pulled the drive out the cross bearings and gimbal bearings seem fine. Can this be cavitation from a worn prop not sure how to determine when a prop should be replaced. Attached is a pic of my prop.

Re: Noise Alpha One Gen II

can you describe the noise, does trim adjustment affect it?

Re: Noise Alpha One Gen II

If your turning and your prop gets closer to the surface the noise would be an increased motor RPM and a lawn mower noise of sorts as air is being introduced into the water around the prop. Would need to see a pic of the other side of the prop to be able to tell if there are ventilation burns on it.
