3 blade or 4 blade prop

[jaybrown]

which is better for speed?

[FORBESAUTO]

Depends on how heavy boat is, but three is generally faster and a 4 blade packs the weight better.

[jaybrown]

the 4 blade would be going on a hydrostream voyager 24 pitch

I was advised to run a 4 Blade SS prop on my 16 Schuster Tahiti with a 150 Optimax hanging off the back. The Bass Boat guys told me I needed the lift of a 4 blade to get the transom up and out of the water. I started with a 20 P MI Wheel and it really worked, now running a 22 P 14.5 and the hole shot is brutal as the bow goes up lays flat and doing 30 mph......Hate to be a skier behind it. next will be a 23 P Ballistic MI Wheel.

I still need to get the Jack Plate installed and play around getting a bow tank mounted.

So this is what i have done. 26 pitch raker 3 blade, 3800 rpm 42mph, 23 pitch viper 4200 rpm 48 mph, 24 pitch 4 blade 5000 rpm 50 mph, i just bought a 24 pitch raker 3blade im gonna try this weekend trying to see 55-60 mph whit this set up, 175 johnson on a voyager hydrostream

V bottom or XT bottom? How much setback?

[jaybrown]

V bottom and 5" setback

You'll need ALL the lift you can muster with a 4 blade, I don't think any 3 blade can do it. Need more setback too. You're really underpowered for that size boat so it will be a battle to "get her up".

Ya im looking for a 4 blade for sure the 3 blade cant get her up
