Hey Guys,
Im new to this whole prop deal.. I think i know the basics, based on what i've read over the years, but have some questions that I hope you can help me with.
First off, I understand that a 19 pitch vs a 21 pitch will be a little slower, with a few more RPM and a little quicker out of the hole.
I don't understand what the difference between "Cupped" or not is, or what the benefits/differences between a 3 blade vs. a 4 blade vs. a 5 blade prop.
Besides the rigidity what is the advantage of a stainless prop?
Here is my boat setup, help me pick the ideal prop!
1997 Crownline Bowrider 22.5ft. 350 Mag/ Bravo 1 with 300hp. I am not positive, but I think its a 1.5 gear ratio.
I have not paid much attention to RPMs Vs. Speed, but I know that I've run somewhere between 4 and 4500rpm at about 52-55mph with an aluminum 19" prop.
I mainly use the boat for watersports, and would like to have the boat plane out quickly. I don't do much high RPM/high speed cruising.
I am satisfied with the boats speed, I would just like to jump out of the water a little quicker and plane off a little quicker.
Right now as it is its a little difficult to pull a kneeboarder at 20mph because its right at that point where the boat wants to either take off or not be fully planed out.
SHould I be using a 4 Blade, 3 Blade? Stainless or ALum?
thanks alot guys
