Supra SL Prop RPMs and GPH

[Jeepers]

Yes the 16x12 we have discussed. Elevated concept was going to try one out. Waiting on his findings. I was worried about clearance to bottom of boat.

As long as you have 1/2” between the outermost blade tip and the hull you’re good. Just make sure it clears the trailer! It’s pretty easy to raise the rear trailer bunk with a poly spacer though. I would bet there’s room for a 16.25 or 16.50! But a 16 should be plenty!

I’m interested to hear the results!

I finally received my 2775 and spent a few hours with it. I’ve now tried all 3 factory props and this is definitely the right surf prop for my sl450. It knocked about 3-400 off my surf rpms and definitely lower rpms cruising back to the dock. Averaged 6.5 GPH for the first 4 hours and that was with a lot of starts and stops while my ids were working on new trips. Surfing 11.2 mph with 2 in the boat + 900lbs lead and a full tank.

I ran the OJ950 the rest of the week. And I like it over the 2775. ran 3600-3700 RPM for most of the week. 11.6-12mph. 600 extra lead. 4 adults 3 kids. The 2775 and 950 are very very similar.
