Sorry. 4.
I believe it's Cat. Brand new, no DEF, well over the 75hp.
Thanks for that. What I found searching was for a no DEF CAT engine is above 750hp for stationary application. So I guess you’re right that’s off road. I was thinking more along the lines of something used in construction equipment.
Cool tech though. Something is going to have to change. Nothing but problems with after-treatment systems thus far.
