Anybody have a comparison on how the whirlwind SW compares to the sensenich S blade. Might need to add a blade and would consider the change considering the S seems to be low on the production priority list anymore.

The Whirlwind like more rpm and tend to push more on the top. Had a buddy do a direct swap.

The S blades pushed very well down low and up the power curve.

We recently tried a new carbon fiber JX race set up and it was a great prop. It needed a bit more rpm over the S blades but when it came in range the snap was better than the S set up. The S feels like a soft steady push the JX feels like a bump when it comes in to range. The JX appeared to offer about the same top rpm thrust based on SOP observation. We were in a heavy loaded 16ft and the JX made it look easy to break ground.

I am keeping the S blades fyi

Pain we run 4 blades the S (81.5) have the pitch marks and they are pitched at a 2 1/4 to 2 1/2 then with the new JX (82) they are the narrow shank design and are set by degrees. I can't recall the exact degree setting we settled on in the testing as we bounced around but I think it was in the 25-28 degree range.

The JX blades were the full carbon light weigh race version borrowed of a twin turbo LS build a buddy is doing. He was pretty impressed with the way they acted Russ they just snapped up in an instant. They made my boat sportier

Just an old Branch built Cadillac on a 2.55 ratio Ox Drive
