Post Gen III PD Props
Has anyone played with some new props for these motors yet? Seems like us with smaller/lighter boats could get more out of our rig with a bigger prop. My rig runs its best at 45-4600 rpms empty and don't drop off much at all with a 3-4 man load.
When I mod my motor I'll have to have more prop to do much

I found some chopper props that would really work for y'all needs problem is they are almost 400$ for a test prop I don't know many people with pockets that deep for a maybe

They left hand and have a variety of pitches.

If u wanna send me your prop I can pitch it up for ya and see how much more you'll gain .. I pitched an old gen 2. 3 blade to a 20 pitch for Mac and he could turn it well

Let me know how it runs. I know this one dont run very well speed wise. It looks to me about ~2mph slower as opposed to the GEN2 lower and prop with same mods....

I think for all around usage and how i use a boat i would like the new gear. It grew on me....The power to eat though float is unreal and i always seem to have a good load with me. Typically have 3-4 bowifishing and 2-3 hunting.

I think that gear with a little better engine. Or an engine that can turn 5000 safely would be a good combo.

What's your rev limit? If you're telling me you are turning it 4700 then what's the ratio of the LU.

What speed btw?

4700, 1.5 ratio, 20p prop, factoring in 10% slip which is conservative for a surface piercing propellor equates to 53.4 mph.

2:1 ratio equates to around 40mph.

2:1 is what he has, and I believe that is an 11" prop

Ok, so factoring in more slip puts him at 35-36mph.

That puts him at 23% slip, a little more cup should do the trick.
