Hi Martin. The engines(225-250) have the same gearing 1,85. and we used the same props Raker26. that why we had the same speed. But the engines are not aloud to do that many rpm. (6100) so have some new props coming.
When you look at boats, A fast boat is flat. and for ruf sea deepV like the scorpion. but if you go fast in a deepV 58 and up the boats start getting wobble. here it's the pilot to show what he can and understand the boat... I drive my boat with no wobling 63kn. I can also do a 360 turn in about 12meter with 43kn. I have seen pilots do a sharp turn and didn't understand the boat. next happen't is the keel tuching the water again and turn over the pilot left the boat..
also remember all boats have a speed limit. Hull-gearbox's
