Of course for insurance reasons, I'm sure it wont go over 70, right? Ha Ha. Twin turbo, big motor, light lay-up. Sounds like a rocket with NASA technology.
Actually, it will be a single turbo the size of a motorcycle helmet, and it will be heavily restricted as delivered.
It will do 70. It will deliver with less than 600hp. This is for sure.
Also for sure is that it will develop nearly 1000hp for free if you want to wad up your motor warranty. But, with the serious benefit from an insurance perspective combined with the reality that 70 is really, really fast and if you outrun everyone in the low end who cares... I anticipate the boat delivering with plenty of power with no mods.
