Default Which 4 blade prop for 20' ma

Hey there I know there is a lot of info about props on here for the 20' boats running a 3 blade, but I can't find out what size 4 blade to try. I have a '02 master angler with a T-top which I just repowered with a new df140 and I'm currently am running a 14x20 three blade SS Suzuki prop. With 70 gal. Of fuel and 2 people I'm running 37, 38 mph at 6000 rpm. I would like to try a 4 blade for a little more stern lift so if anyone is running my similar set up with one I would like to know what performance numbers they're seeing and what diameter and pitch. Thanks

I'm running a Solas Amita 4 13.75 X 19P 4 blade aluminum. I get 34.5kts @ 6100 rpm. Great hole shot.

Thanks for the info Capt loyd I'll start looking for a prop with those specs and try it out. Holeshot was something that I would like to improve a bit. I'll report back with performance numbers once I find a prop to try.

Denny has tried a lot of props. I`ve tested many with him.
His final pick was a BRP cyclone. Held plane at 12 mph.

Verified. Was out this morning on RL III with my son. A friend met us in his Aluma-something. We stayed on plane at 12-14 mph in a tight chop while they got pushed all over the place trying to keep pace.

Bushwacker’s “Prop Test” sticky is a must-read for you. He ended up with a 14.5 x 15P BRP Cyclone.

The 15x15 PT ofs was on point.

My Seafari has great performance with a PowerTech OFS4 15x15 also. Haven’t tried it on the MA yet. She’s running a 15x15 OMC also in Stainless.

Vezo.

The Seafari has a transom mounted ‘06 Etec 150. The Master Angler has a transom mounted ‘99 Johnson 175 carbed.
