Aside from "ease of docking" it seems like there is no point to put twin diesels into a boat under 35 feet or so, unless you already have twin applications to start with.

How about one of these?

Volvo Penta states that this system is designed for over 45 knots to 60+knots...

Very nice for reliability and longevity but 45-60 knots your not going to be flying. Pat how much $$$$$. Perhaps you could put a pair in ????

Remember horsepower is a calculated number from torque and rpm; torque is a measured value and what really counts. This engine maxes out at 3500rpm thus its 350HP rating.
I would bet with the right gearing and props, a 30' Super would run well over 70mph and maybe even 80 with this package...
As for the cost, I have no idea???
I have no desire to bolt a diesel in any boat at this stage of the game, but it was the subject of this thread...

Just an opinion, a nice set-up on a 30-Y2K would be a Volvo 8.1GXi (420HP) coupled to their DPR Drive (high-speed drive w/ X-act Steering).

Volvo Penta did have a DPX drive offered with a 600HP BBC a few years back.
I wonder how a 30' Super would run with a Volvo dual prop?
That sounds like a good subject for a new thread...

Re: Diesel Application in a 30' Superboat
Not to get TOO off topic but what is everyone's thoughts on a 24 with say a Marine Diesel-USA Hammerhead or Tigershark mounted to a Konrad (or any beefed up drive)? Is it worth it? Will the speeds still be respectable?
