I have a 2017 Ranger Z521c with Mercury ProXS 250hp 2 stroke. No talons or PPs. Fully loaded this has always been a great boat. I could get 5850-5950 RPMs and run 68-70. Always been a bit relative to conditions of air and water temp as usual for most or all boat/motors. Currently running a Mercury Fury 24p 3 blade. Typically this has been the best overall prop for me and gave me the best numbers.
But recently I can’t get close to those numbers. Been unable to get over 5600ish RPMs or 58ish mph.
Any ideas.
Thanks in advance.
