Princraft pro FnP 196 , yr 2000
Evinrude ficht RAM 150
Range WOT 4500-5500
Principal use : 75% puling tube and sky, 25% fishing, onboard 3 adults/2 kids

Present propeller 15x17p Aluminum, WOT ?5400 , 72 km/h

I am changing for a SS propeller, but have a few questions :
-From Aluminum to SS , does it change the WOT.
-Since the principal use of this boat is in the lower range speed, would you agree that a 4 blades SS propeller is best suited.
-The 4 blades SS propeller give a better hole shot, earlyer planing at slower speed, but usualy lower top speed, could it be compensated by a high rake.
-High rake, does it decrease the effectiveness the propeller for the hole shot since the angulation diminish the surface of the blades.
-Rake and cuping have effects on the WOT, but is it calculated in the pitch given by tha manufacturer of the propeller or do I have to make the conversion myself.

If you had to choose a propeller, by order : they are all cupse
1- Solas HR Titan 4 Blade Stainless 14.25" dia. X 17" pitch
2- Stiletto Bay Pro II 4 blades 14" dia.X 18" pitch
3- Solas HR Titan 4 Blade Stainless 14.13" dia. X 19" pitch
4- something else...

I think the prop forum is the best place to post this, those guys are the experts.

Re: Choice of propeller

Question - why are you considering the Bay Pro II rather than the Bay Pro III?
