The cummins 12 valve 5.9 can be found on earth moving and construction equpment also you might find some deals there too..plus rebuilding one is CHEAP even in Europe.

Is that the same PPE that engineers the chips/tuners for the duramax's. Any idea when they might go into production.

I agree with you on this.

Question: Did you use the 6LY3-ETP (480HP) motors in your new boat, and did you modify them at all? Was not sure if/how well they could be tweaked in a marine application vs. what you can do in a truck.

I don't think that is production. The manifolds and turbine housing don't look water cooled.

If only the drives that were designed to handle that kind of torque were as inexpensive.

The Mercruiser Cummins 5.9 inboard weighes 1290 without transmission, while a Mercury Marine Horizon 496 inboard weights 1130 with Velvet Drive transmission.
