Hi--got a problem. Maybe someone has had the same--What prop for Honda 90?

Just repowered from a 90 Evinrude--prop 13 1/4 x 17. Good performance at 4600 or so aroung 37 mph--non GPS.

The prop that came on my Honda--13 X 14 is way too flat--I turn 6300 --GPS speed 31mph.

Should I go to a 14 X 16 or stick with the 13 and go to a 17 pitch??

I hope to get around 42 mph at 6000 rpm. My use is general--fishing and sport--some sking.

Thanks

I don't see your exact boat listed for the 90HP but maybe some other boat listed is similar. I hope this helps:

Thanks for reminder---I went back and checked again and charted results based on weight and length--closest I could come.

I am thinking of a 13 1/4 x 19 and if I don't like it or it is too much over 6000 then I'll spring for a change of pitch.
Later--I'll watch for a used stainless or a maybe a nice present to my self--presently--all is still new to me--engine while used is super--I bought new controls as old one sold with Evinrude I took off.--I had to change all wiring which later discovered I coulda stripped from old side mount (guy had it on a pontoon bt).
I will read this site from now on--avidly--- as I wasted lots of $$ on calling Honda etc. with some expensive advice which wasn't necessary.

Next project will be to mod the controller for smoother operation.

Thanks
