Ribcraft 4.8 with Yamaha 75hp
Hi,
I've just bought a Yamaha 75 2 stroke for my 4.8 ribcraft and was wondering what prop size to use and what sort of speed it should achieve?
Many thanks

12x17pitch.. you could even go to a 19 pitch would be a fast and reasonable choice subject to loadings etc

A 15 is the correct prop for a 5.4Sr. I would go with 17 or 19
