Prop advise please

[520runner]

I put a new 225 SHO on my 2002 Ranger 520 recently. I am running a 25 Tempest Plus to 68-70 MPH @ 5400-5500 no jackplate.

I would like to get close to 6000 rpm. Yamaha SHO props are backordered. Any advise as to another alternative prop? Would a Fury 4 in 24p work?

Also would adding a jackplate get me any more rpm's

thanks

Test a 23P Tempest Plus if you can...
