Prop Recommendations

[C]

Looking for prop recommendations for a GT 150 with a 2013 Evinrude Etec 90hp? Is anyone running a similar motor?

I'm not sure on newer Rude's .. But Merc's geared there motors to run props in the 17 to 25 pitch range, with most running in the 19 to 23 pitch range.
Did you get a tach to see your max RPM's ?
Ask your local boat dealer who repair props for them or check around for a prop shop.
They might let you buy one .. then change props until you find one that work best for you.
OR check Facebook Marketplace or Craigslist for used props. Buy and sell the ones that don't work.

I did get a tach, here are the new gauges. At this point, I?ll probably wait till spring to get the prop figured out.
