Anyone using one yet? Im waiting for a quote from NW cummins. Also waiting for a quote for adding another D6 370 to the 34ft boat to make it a twin. Kicking around the idea of running a single cummins 6.7L with a Konrad drive verses a twin Volvo D6 with twin DPH drives. I already know what potbuilder is going to say, but is anyone running a the Cummins Konrad package?
