I run the 16X 13 on my fi23 surf RPMS  are at 3600  boat has the 409 with 1 1/8 shaft. Tried other props but the 16 X 13 works best

Old post - but wanted to update.  I’m using 16x13 prop, have 200 hours on the boat now.  And getting 5gph average.  Seems that between the break in hours and bigger prop- I’ve seen gains in efficiency

Running a 2020 fi21 with 16x13 prop. Surfs well prop handles max ballast and max crew.

Took a huge hit on cruising speed 20 MPH @ 3800 RPM. Elevation 1200 ft.

Don't mind the slo roll makes getting around more like a party.
