Why do you guys think we haven't seem a turbo'd boat motor yet? Inter-cooling shouldn't be too difficult with water plumbed on board and the motors seem like they could be ideal for wake boats given a long flat torque curve would be ideal in our application. Peak torque would come in right where need to be on plane or getting on plane (BMW n55 around 2k and fords EB v-6 around 3k) with a steady curve from low rpms to mid range not to mention a simple tune makes some pretty loony numbers.
There are boosted jet skis and super charged wake boats but why no turbo? Does it just stem from the fact that its too expensive? On boost all the time? Difficult to marinize? I'd be interested to know why it hasn't been done, perhaps they are in development...
