Need some help on props? *What I have is a '12 xb-21 pro sport with a '05 300x *1.75 sporty (allison mods)with a tuner, poppet and Simon throttle body, limiter is 7100 rpm. *With a full fishing load 450lbs two 200lbs men , 3/4 fuel and a full live well with a hydro 28p QIV-X O/T the boat runs 97mph at 7300rpm which is all over the rev. *With four people it ran 94mph at 7200 ( not so well balanced).*
With a 30 et 200lbs lighter load it ran 101mph at 7400rpm (hole shot was better with the hydro)
Mercury wants it to run at 6700rpm for optimal performance on motor.
I have not ran an empty load solo yet because I don't have a prop to do it without killing the engine. *Don't really want to go to 1.62 gears because of fishing hole shot will suck. *Hydro is going to add some cup and take some nicks out of the 28p to get rpm down and then re pitch if need be.
For a strictly top end empty load xb-21does anyone have any insight on props? *Looking for the fast *top end prop not that worried about lower end performance. *I have been told that even a 32p won't get the rpm wear merc wants them and it could handle like crap, That to get to 6700rpm I'm gonna need to change gears. *Maybe I should just get a 2nd sporty for playing
I've owned xb02s,xb03s, and 2+2s and I have always been a hoss guy but not sure if that is the way to go or not. *Any knowledge will help! You can write back or call me at 352-472-7867 thanks ,Bob*
