Which Prop

[will church]

I am getting a new prop for my Yamaha 15hp long shaft, to go on my Sea Nymph (17ft displacement thing like a Longliner)

 

approx 15ft displacement lenght and c.400kgs.

 

What pitch etc do I need?

 

Thanks as ever guys

Will you will be best asking at a local prop shop.

 

I think the local Poole guys in Cobbs Quay are called Propeller Revolutions.

Someone else will be along shortly who may be more helpful.

Thanks Tom

 

I'm waiting for Afishionado to come on because he knows lots of stuff like this!

 

I spoke to Steel Developments and they tell me that if I have a 4 blade prop it will have faster acceleration, and 3 blade will have faster top end - but on a displacement boat with the largest suited engine surely the top end can't be increased?
