Specialty prop

[andrew_ireland]

Hi all, was wondering if anyone knew of or had a 10 inch diameter prop with a 14-19 inch pitch. I'm looking for more top speed on my rib (30hp 2-stroke tohatsu 2006)

It's not just a case of fitting a bigger prop and you go faster.
You need to start by checking what your engine is reving to with your current prop if the engine rpms are within spec then fitting a larger prop could overload the engine and potentially make you slower.
If your rpms are at max or slightly over rated rpm then you can start increasing pitch, 2" increase in pitch will be roughly 300 rpm reduction but you need to stay within the engines rated rpm range

I know all about the ideal revs etc as I have researched this already, now just trying to find a prop

How heavy is your boat? We had a 10x15 chopper on my old Ceasar Surfcat with tohatsu 30hp same as yours, could have done with a bit more pitch but it was a very light boat. A normal style prop I think a 10x14p stainless would be best
