Noise from prop area

[David 01]

Hi all, I have had a noise develop from my prop area on my beneteau 42
It sounds like it is coming from directly beneath my feet at the wheel, I have taken a recording from the rear locker,
The sound comes in at about 1300rpm and goes at about 1800-1900rpm in the video I am increasing and decreasing the throttle at around the 1300rpm mark, if anybody could help that would be great and much appreciated. Thanks.

You may find you get a better respnse with this in the 'Reader to Reader' section.
Could you describe the sound as there isn't any attachment with your post so can't even try to identify the sound.

If it's screech like a slipping fan belt then it is just the Cutless bearing rubbing on the shaft and not unusual.

Hi pcuk, thanks for your reply, funny enough it sounds just like that, I've never heard it before and sounds quite scary, it hasn't sounded like that before

I used to get it on my boat at certain speeds but it never caused any problems. You may want to fit a new bearing at some point if it is worrying you.

I have exactly the same noise on my motor boat. Been the same for 10 years. I was told it might be the prop singing. I just ignore it now

Thanks for all of your replies, I had the boat lifted and inspected and the propshaft is resting against the through hull so the engine is out of alignment due to a tired engine mount, was a bit of play in the cutlass so having that replaced also.

Glad you found the problem!
