255 HP Speedster
Sounds great and I almost purchased one myself, but after further review I decided with the 155 HP instead. We don't wake board or water ski so the extra HP would simply be "extra". The supercharger has to rebuilt every 100 hours at the cost of about 800-900 bucks. We boat year round here in Florida and 100 hours come quick. It requires an 92 octane for optimal performance and that means you're going to have to haul gas to your boat unless you have a marina that sells 92 octane or you sacrifice performance.
If you don't put a lot of hours on the boat per year and you don't mind hauling gas to the boat I too would prefer to have the extra HP,but I'm a guy and more power is always better.
