I bought a 2022 X21 with 250 SHO expecting mid 70s. I can’t hit 70 loaded. Just me(225 lbs), tackle and full tank of fuel. I’ve tested numerous props and all basically same top end speed. Within 1-2 mph. 68-69 with all these props.
25p Fury 3. Rev limiter
25p Tempest rev limiter
26p Trophy rev limiter
25p powertech rev limiter
28p Bravo I xs 5800 rpm
27p fxp and turbo 5500 rpm
this is a pretty wide variety to achieve same top speed. My set up is in my signature. The welds seem smooth at the transom except the two on the outside that’s supposedly to keep it from porpoising. Any help would be greatly appreciated
