Well its May 20 , and still waiting for the boat dealer , they called last week and said they tried installing the camper top but Tracker sent the wrong size :-( still waiting to bring it home. Mechanic said he tried out the 15p x7 prop and got 40mph but only 5400 rpm .....That means with a full tank of gas and fat me and a friend rpm could be low as 5000 wot....i hope not !! just guessing hoping for the best.

Well the best I could do with the spitfire 13.5 x 15p x7 was 38mph and a max rpm 5500. The spitfire x7 14 x 13p produced 35.5 mph with a rpm 5850 better hole shot but lost 2.5 mph . So after doing more testing it seem the 13p is better on the boat because when i added two more people or 370lbs my speed and rpm stayed the same.I can live with 35 mph after all it's a fishing boat.

I have a 2018 V175 came with the 17 pitch prop and could only get 31 mph at 5200 rpm. Put on a 15 pitch and get 33 mph at 6000 rpm. I get the rpm i want but not any more top end speed to speak of. I want to try a 4 blade 15 pitch to see if i can get a few more mph, plus better plane without so much side spray. I am getting side spray perpendicular to the drivers seat which tells me I am not fully on plane even though I am trimmed out fully. Any input would be welcomed............happy boating.

I have a 2014 pro guide v175 sc, with a 2014 Merc 115 4 stroke. I have a solas stainless 17p 3 blade and am hitting 6000+ with 2 people. I get 37-41 mph depending on water and load. I tend to keep it at 5k or so for cruising. I'm looking for a prop that will max at 5500 rpms or so, so I figure I'll need to go 19p.

For the guy who can't get a 17 pitch to spin fast enough, look at the bottom of the hull. Granted, my rig is lighter without the wr windshield and such, but you may have some dents in the bottom of the hull or perhaps a transducer is way too low or something.

If any of you are near memphis or Greer's Ferry Lake, I'd be happy to do some prop swapping to try different options.

Wait, that's on a 90hp? Well done!
