Prop size for wakeboarding
I've got a 4 meter rib with an old 40hp mariner 2 stroke, at the moment its got a good top speed but really struggles to pull me out of the water wakeboarding, with 3 people on board it won't manage it at all.
The pitch on the prop is 13. would you recommend going for a 12 or 11 pitch prop to replace it, i would prefer the 12 if you think it will pull much better but will go down to 11 if needed. also how much will the top speed be effected, i'll need it to stil do 22 knots, it does around 30 with the current prop.
thanks very much
