I have 25hp prodrive. I'm curious to know if changing prop will help with heavier loads and getting on top of water faster. Problem is I can't seem to find anyone who makes an aftermarket prop for this motor. Any help is appreciated.

10-4 thanks.

I hear ya. I was just curious because ive been reading on all these different props that say they improve hole shots and other areas as well. I wasn't able to find anything specifically designed for my motor and I'm a rookie when it comes to mechanics so I was unsure of what to do. thanks for your info.

Is your shaft threaded or splined?

Threaded

You have a lot of options. Standard 2 or 3 blade from PD, Hopkins Cleaver and I think LA Prop has another style similar to the Big Blade....don't quote me on the last one....check with him.

Or better yet have your prop shaft replaced with one with a hex on it like Gatortail and MudBuddy, then your prop options are expanded.

ok ill look into all that. thanks for the help. I also saw where backwater performance makes a prop for a 3/4" threaded shaft but not sure how it would work with gear ratio of pd.

unfortunately I'm not in the financial position to just unload my current motor and replace it with a bigger one. I understand a big block is a lot stronger that's just not an option for me right now.

Three blade helps my 25 Prodrive when got a load

Which 3 blade?

Chris at LA Prop put me in touch with the guy. I’ll have to look for his number. Basically I sent him my shaft, he built one and put my gears, bearings, and such on. Jam up guy.

Can someone tell me exactly which shaft styles ProDrive has used through the different generations?

Only thing with doing this is that you need to have a built prop since Prodrive has a lower gear ratio that other manufacturers. I had a stage 2 motor and could bury a worked 3 blade and bounce off the limiter. The big blade that was on it when I sold it was built with a ton of cup. It wasn’t perfect but was manageable. I would think a gen 3 would be tricky to find a prop to work.

Without a doubt.

if my pd shaft was splined instead what options would I have for props then? not familiar with what pitch or size props this motor can handle

You might could spin a stock Big blade. Hard to say since mine was a stage 2 big block.

i have bps q exhaust with fuel tuner but that’s as far as I’ve gone with mods so far

My brother just had his Gen2 threaded driveshaft swapped to a hex... Nick Peltier fixed us up...
