Is the new boat not performing as well as you hoped? |
Bigfishbob wrote: Yeah max recommended Horsepower, believe it or not is more fuel efficient and the boat will handle better. having said that, even when choosing an engine for top of the range horsepower, go for the one with the largest displacement. It will have more mid-range torque, which also help performance. Also check torque comparison figures as well, logically more displacement equals more torque, but some engines get more torque with different cams and fuel and spark management, from lower displacement engines. |

When it gets sloppy can trim up and the nose sits up nice and high and it rides well. Your design seems to have a lot of weight forward so will tend to nose down unless power on tilt up. I put a $150 hydrofoil on at xmas as an experiment, so far success. Extra 3 kn top speed flat water but more importantly it lifts the arse end up and sits comfortably on the plane 12kn with the nose up high so the hull can do its work when it gets ****ty. |
