Stainless certainly gives better performance, if you are willing to pay the price. however, alum is more forgiving, more repairable and cheaper. and a change in pitch can make all the performance difference stainless can. as well as the option of going to a 4 blade alum prop. if you go to a stainless, same diameter and pitch and you will still see a differnce in performance. if you go with more blades, same diameter and pitch and you will see a difference. lower pitch allows the motor to rev higher, so be aware of starting top speed rpms. higher pitch slows the motors top rpms, and gives you a better hole shot. but a lower top speed. as i bleive rinker uses merc motors, check this link out. its merc's prop selector tool. mercurymarine.com/ propellers/ prop-selector/ # |
