Propeller shaft dimension Oceanis 343 Clipper

Hi!

I wonder to buy a new propeller from a guy who sells a propeller previously used on a Beneteau Oceanis 343 Clipper. The seller knows nothing about the prop and its dimensions ... Is there anyone here who knows the dimension of the shaft on the Oceanis 343 Clipper?

Call Beneteau USA in South Carolina. I've asked them a couple questions about my Beneteau and they had answers. It probably won't help you but mine was built in France and has a 30mm shaft as does a friend's boat that is nearly 10 years newer.

Every Beneteau 343 I've ever worked on had a 25mm shaft.

Hi
I am suspicious of my propeller is not the right size or type. How can I figure original size or type of 343 propeller?

thanks

Asking here is a good start. I'm sure somebody with a sister ship can tell you what the factory prop specs are. Do you know what's on your boat now?

Re: Propeller shaft dimension Oceanis 343 Clipper

There's more to this than just shaft size. There are different tapers on the shaft that the prop must have or get machined. If I were you, I'd pay someone at a prop shop to check things out, just like you would hire a surveyor before purchasing a boat or a sailmaker before purchasing a used sail. Use the expertise of the experts, in this case.

no. but I only get 2600 rpm max. and after 2500, smoke and fuel at exhaust. I was told the prop may be too big.

Or it could have too much pitch, which again can be easily (up to a point) remedied by any reputable prop shop. Every prop manufacturer has a form you can fill out online to get their recommended prop for any boat. Remember, you boat could have a different engine or transmission from others of the same model if your boat has been repowered. Just assuming your boat is as built could be a very expensive mistake.
