Any good?
Look nice, not that that means a lot.

looks awesome,wounder what the price is thow.

Saw those at the IBEX show, looked bad azz. It looked like it was being marketed to big power wake board boats as i saw this motor with a pretty steep V drive trans attached to it. I also learned that engines over 500hp are exempt from the new emission laws which i would guess is why you are seeing new players like this. Awesome numbers, would think this would be right at home in a offshore rig in the thirty to thirty five foot range

I use there ecm package on my ls ,they where one of the first that had a stand alone wiring harness for the ls engines when I was shopping in 2008 .

back then they where building the marine version which took quite some time so I think there have thought it over and was not build in one day .

Had several times contact about the software and mapping and there where very helpful from the president to the sales department .

I see their street N/A engines are 16,000$ as a long block so I gotta imagine the marine ones are 25,000+ with pulleys/accessorys

Mast is huge into all the LS stuff as for the marine side this motor 2 years started to be advertised was close to 30 k retail. It uses EControl's for the ECM & CMI headers. As of this year not one has been installed in a boat but currently not sure if things has changed.

A pair of those in an old 30' Velocity might get me to walk away from my clip on's
Personally I think that would be one bad ass combination.
