What will it do

[rib-x450]

My 4.5m rib today pulled 41.5 mph on the gps with two adults ooppsne child and approx 20l of fuel. (rib-x 450 boat)

Running a mercury 60 with 14 pitch prop at 5200 rpm.

I thought that was quite good.............

Anyone managed to get more from a 4,5m rib?

the speed is high, but 5200 rpm is a bit low, I would suggest to test with a 1" lower pitch prop to reach 5500/5600

38 mph with 80 l of fuel, 2 adults, 1 child. Prop pitch 13" at approx 5300-5600
