First picture is Kingsbridge, second is Salcombe, third is Brancaster.
I always go to Salcombe but tried Brancaster once because I used to go years ago.

Ah, it looked very South Devon/Cornwall. I couldn't place it.

Like said, top speed is not interesting for me.

15' prop @ 5200 rpm (max for E-Tec 90) is 32 knots....(0% slip)
i got 35-36 knots with my old DT65 Suzuki (16' @5800 rpm).

Speed and hp is not directly related ;-) so i don't really get your comparison !
gearbox, rpm, prop ect. is more important....

I think you need to raise that engine the E-tecs like to run quite high. Also try a viper prop. On a 4.7 I would be suprised if you can't get 40 knots.

A 15" prop is very fine for a 2.01:1 LU ratio, so I assume you're running the boat very heavily laden? Conversely, your set-up with the DT65 suggests a reasonably lightly laden boat.

Speed & hp are related. As one increases, so does the other (all other aspects remaining constant).

i'm quite sure my engine needs to be raised... it's on my todo.

picture of the antiventilationplate @ 20 knots:

but the viper is made for speed... i'd rather go with the Rogue (lower planning speed & stern lift).

the hole shot is amassing now compared to the DT65, and it's needed when the boat is loaded with diving equipment. and the fuel consumption reduced by 60%

That's hardly surprising, given the power difference and propellers fitted to each motor.
