TomBettle Posted June 21, 2006 Report Share Posted June 21, 2006 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. Tom Quote Link to comment Share on other sites More sharing options...
will church Posted June 21, 2006 Author Report Share Posted June 21, 2006 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?
