    I couldn't resist!! Supra has released the new model information. Let's SEe how long before Moomba does. They might be a little SLower, but I am going to SAy it won't be long. Of course that is just this old SR's opinion.

    I swapped to a Acme 15.5 x 13.0. Lost a lot of top end speed, but it does surf better. Thinking of maybe sending back for 15.5 x 14.5. FWIW I emailed OJ props and the 15.5 x 15.0 is what they suggested for surf specific.
    I called ACME and discussed the elevation and weight I was running at with them and they claimed the ACME 3407 (15.5x13x0.150, radius/pitch/cup) was the one I needed. I had used the ACME 2775 (15x12.5x0.075) last summer but the RPM's were so high and I was burning too much fuel. The stock OJ 930 (15.5x15x0.120) could barely get me out of the water and really struggled with the extra weight and pitch.

    I run max nameplate weight at 3000' elevation and wanted to get down below 4400 rpm's at 11mph, 10 degree pitch. All of those factors together pushed me to the new prop. I don't know where the sweet spot would be, (maybe 15.5x14x0.150) but I felt the OJ 930 was very underwhelming.

    If HFarr was able to make it work, then all the power to him. It definitely was not the case for me. I would want the "altitude/wake" prop to carry max nameplate on Lake Tahoe 6200'.

    I am basically at sea level where I run too.

    Stopped by our local dealer today. They have a real nice 23 Mojo they just got in for their demo boat.

    Raspberry with Black on the bottom hull. Darker interior seats with the light brown Gator Floor. Very sharp.

    I think this one had some custom 1200# bags in the back and a different bag in the front. Doubt those came from the factory. Probably will some lead to move around. Betting it will throw some monsters. Looked like a great boat. Also was told about a 23 update on the interior.

    Looked at a pic from the recent dealer days on a different model. Stock wave was ‘crazy’. I think people are going to like what they see. Stepping up the competition on the Axis.

    What effect does the cup on a prop have? The 3407 (15.5x13x.0.150) has slightly different cup than the
    3892 (15.5x14x0.105).

    Here is a quick down and dirty, but there are several other videos that do a very good job of explaining how pitch and cup work together. https://youtu.be/WTVAPXQOosk

    Makes sense. So is 0.15 more or less cup than 0.105? Just not sure how that's measured.
