Prop advice
Need some advice on what prop I should go with, here is my boat info
2012 pathfinder 20' with f150 and power tech SCD 13.25 x 19" prop
Currently with just me, 1/2 of the livewel full, half tank of fuel, normal gear and medium cooler with 10lbs of ice, no trim on motor and tabs up I can just barely hit 5500 RPM @ 44mph. I feel lightly loaded it would be best to be able to get near 6k RPM and that would more efficiency with light loads and better performance with heavier loads. This boat in general is noted to be a little heavy at the stern & has a slight tendency to porpoise under certain conditions. The above prop was the generally recommended one due to its stern lifting properties. This same prop is available in a 17 & 18" Im guessing the 17 would put the RPMs where I want them and is also made in a 3 blade version. So I am wondering should I stay with 4 blades or go with 3, and also what other style props might work well with this setup and give the numbers I want?

I agree. I bet you drop pitch a couple inches, you'll be in 6500-limiter trimmed out. Shorter engine life. Plus i bet you won't gain 1 mph.
I love PT props but to me they seem too thick to be turned by a less torque 4 stroke or smaller motors. I feel a thinner bladed steel prop might be the ticket. Been asking if anyone has run a 19 SST on theirs.
BTW I also run a 17x14 1/4 but it hits the limiter pretty easily and my cruise speed say at 3900 fell off a good bit from the 19 which is at 34mph. Note* My boat is the newer Cobia Bay that Maverick knocked off the 20' PF.
