I just picked up the 17p eco for my 23 with a single f250. I went with 17p as I read that the prop is pitch higher and is also variable. The 17 seems to be about a 19p. The prop is noticeably bigger 16" dia and also the blades have a lot of meat. When i first put the boat in gear the other day I noticed it moves a lot of water just in idle.
The numbers before 47+/-mph WOT @ 58-5900 rpm, sucking about 17-18 gph, fast cruise around 28-29 mph @ 41-4200 rpm burning 12gph
or 3800 rpm @ 25 mph @ 9-10 gph normal cruise
after WOT 46ish @ 6000 rpm, 3800 rpm @ 29 mph and 7-8 gph. Fast cruise was about 31 mph @ 4200 rpm and 9 gph.
The prop hooked up real well. good hole shot even with all three plugs in prop. stuck in with no significant ventilation when at fast cruise and doing sharp 360 turns.
So far so good and worth the investment. I had to get a prop though as my mirage plus 19 fell of when the hub failed, weirdest thing. I got a good deal from a shop in Wisconsin, way cheaper than other stores online and local here in Florida.
I could have gone with a 19p maybe. But I need to see how the boat would run with a full load first.
