2000 formula 280BR. Twin 350 Mag mpi with bravo 3s, 2.0 ratio.
Tried hill marine 4x4 24 p props but considering going down to 22. Loaded with 6 adults and 7 kids under 8 years old, I could only muster 3800 rpm at 38 mph via gps. This was the best result i could get playing with trim and tabs down.
Same props with 4 adults, 4 kids under 8, I could get 47mph at 4400 rpm.
Was surprised by the way the addition of 1 family (2 adults+2kids) changed WOT performance.
Is this normal?
im getting feedback that I should easily be able to turn 5000 rpm at WOT with this setup.
where do I go from here? Compression test? Check drive toe in/toe out?
