Yamaha F150 vs new SHO Max150

[JAMS]

Have a 2021 LL 21 SPS package, Seastar steering, SS 14.5 x 15 prop (Yamaha recommends) top speed with 2 at 5900 RPM 41 mph. I would like more speed and bit better hole shot. Would changing to the new 2024 SHO max 150, which is 29 lbs lighter provide better performance and would it allow for a prop with around a 16 to 17 pitch ? Or how about changing to a SHO max 175. has anyone changed to a 175 on a 21 foot with the package I have. thank you

You’re only going to squeeze so much out of a 150…and what you have now is really good. If you did that switch, I think the best you’re looking at is 2, maybe 3 mph. Should see better hole shot, and that’s probably the noticeable change. Lots of cost for little gain.

As for prop…15 is probably topping out either way. Just too narrow a range. For reference, even with a performance oriented 200hp motor on a tritoon, you’re typically looking at a 15-16p prop tops.
