I have a speedboat with clear hull lenght 6.2 meters. Used to have a 5.7Gi Volvo engine with DP-C1 drive 1.95 ratio B6 props. I changed to KAD 42P-A and kept the same drive and props. AT WOT I can see 3600 RPM, usually I cruise at 2900-3000 Rpm 27-29 knots. Do I have a problem that the drive is not the 1.78 ratio, is my current drive weak for this engine? Does it matter for the engine not to reach the 3800 rpm max level? Do I need to change th eprops to B5?

Thanks a lot
