Grady, I went with volvo because of the shape of the engine you can tuck it down into the hull of a DE. The cummins has a cooling tank that gats in the way when you try and get the engine under the deck. As far as cats are concerned I have just never been a fan of the 31 series engines and I would need the 3196 to get the HP I wanted.
Fuel consumption, I'm not really sure witch burn more or less. I believe with the newer electronic engines they don't vary too much from one to another.
Yes we built the entire boat ourselves, big job but when your done you have exactly what you want and you know that its done right.
