Derated c12 ?

[long-cours.62]

I saw the C12 could be de rated from 705 hp (pleasure use) to 350hp professional use .
Anyone have an idea of the potential cost to do that ?
Change injector ( or more) or only "data" ?

Interesting idea, will follow so see that the outcome is?

Most larger engines come with service ratings from 1 to 4 .

1, is usually pleasure boat wide open throttle for short periods,

4, is 24/7 for cont usually commercial use.

Its the same engine , same everything , just pulled back and properly loaded for the #4 HP rating .

Happily BMEP (fuel map) info can usually be had for this size engine so the tranny and prop can be optimized for your cruise speed.
