Prop advice

Hi I'm new to RIB's and need some advice on prop sizes. I have a 4.8m Gladiator RIB with a Yamaha 60 FEDO. The current prop is slightly damaged and I was thinking of replacing it. Upon inspection the stamps on the prop are K21, and I have been told this pitch is too much and that I would be better off with a 13x17 or 13x19 pitch prop. I have no rev counter on it, so i'm not sure what revs its pulling, but the engine doesnt exactly scream. I tend to use the boat lightly loaded, ie no diving gear etc so what pitch would you suggest 17, 19 or 21????

Any info greatly appreciated, regards richard.

It's very difficult to come up with a recommendation without knowing what RPM you are making.

However, a propeller specialist such as propeller revolutions or steel developments would be able to give you some good information.
