Default Very simple Prop Question

I currently have the standard prop that came with my 2000 Four Winns. It is a 23 pitch with a 14 1/2 diameter, 3 blade.

I want to switch to a stainless steel prop. My question is since I like how the current prop works, do I keep the same dimensions and pitch when I switch to stainless steel?

What kind of differences will it make, in general, in performance?

Thanks for the help!

Eric

A 22" 4-blade should do the trick.

Nick,

Won't changing the pitch and adding a 4th blade decrease my top end? It seems it will also increase my hole shot.

Any reason not stay with the 23, and 3 blade?

Not trying to debate your answer, just want the best prop for my little boat.

Aluminum props will flex to a point , Stainless won't

Eric, props are a funny, kinda like woman,if you can find someone to try different wheels thats the best way to pick a prop, I would think a 3 blade would give you top end over a 4 blade, I've only seen 4 blades work on twin engine set ups, good luck.

I thought the response I would get would be something like, yes keep same pitch, just change to SS.

Crap, now I have to try different props. I will call around for some suggestions, I guess.

Just when you thought you would get a simple answer!!!

A little story about props, I run with a buddy of mine that has the same boat, motors gear, both boats weigh the same, we both use different pitches to obtain the same speed! Go figure!!!!


Nothing is simple when it comes to a boat, I told you their just like woman

Try a 22 pitch turbo 3 blade or a 23 pitch turbo 4 blade. Turbo is a progressive picth prop and works very well. A 4 blade will give you better hadling, and if you can spin the same rpm you shouldnt lose any top end

Eric,
Agreed, Top end usually suffers slightly but going 4-blade, will undoubtedly better your holeshot, make for much better mid-range cruiseing(lower rpm, less wear and tear, better fuel usage) and better acceleration. 4's usually yield the best "all-around" performance. If WOT max top-end is your goal than stay with 3 blades. Typical rule of thumb when going from 3 to 4 blades is to drop down one inch in pitch. The same holds true from aluminum to stainless(down one inch) due to the less flex--Your aluminum will actually flex and flatten out slightly giving you less effective pitch. Hope this help.
