Supra SL Prop RPMs and GPH

[Ryann]

I didn’t have any luck with 10 degrees pitch on my SL at 11-11.5 mph. I liked 8-9 pitch max, and about 3 degrees roll. Fantastic wave for me. Acme 2775 3400 rpm 11.2 mph 9 degrees pitch.

I also noticed that it’s really important to experiment with the wakeplate when playing with autowake. If I wasn’t careful, I would adjust the wakeplate and autowake would drain the bow to get the nose up. I would like to see autowake integrate the wakeplate. Max ballast for displacement, but use that wake plate to fine tune it. The wakeplate does a great job with pitch.

I have always heard that wake plate over 30 starts to lift the tail and counteract your rear ballast. Always aim for 30 or less wakeplate.

Dakotas right you create lift in the rear.

Man wave is insane at pitch of 10.

Gotta try that - we always stay at 8 ... and we got pics but not with my phone so will post tomorrow

I"m not sure how a pitch of 8 you not giving up some displacement. You have to be forcing the nose down some how??

My usual setting is 100% full ballast plus 400 lb lead in rear almost as far back as possible. 0 wake plate usually but we have adjusted it to a max of 50. I usually leave it at 20.

I have been weighing this SL motor debate for a while now thinking this is my next boat. But now, I am really taking a hard look at the maKai and the 450/1.76 option.

If I can be satisfied with the fit and finish of that boat, it would be really hard to ignore the amount of value you get out of it.
