I need your help

[Fatmir Sefa]

Hi there

I have one 4.92m inflatable boat weight 500 kg with yamaha engine type f30,22.1 kw 4 stroke carburetor year 2006.
I would appreciate if you would help me to find the right size of propeller because with what I have now
My rpm can't reach 4400 with one person on board.
Thank you and looking forward for your response.

Regards
Fatmir

might post what prop you are using right now.
and what is the HP rating of the boat?

30hp on a 1100lb boat , not sure if that is a good fit or not

a inflatable boat forum might be a better place to ask this question if you are looking for someone that has real world experience with them
