They run like 525 EFI's around the dock, just awesome. We took a 40 Skater out with Mark's 1330's on Monday. Boat is still being dailed, the motors are amazing.

I have 40 minutes of go pro video from the shake down run. I was a guest on a customers boat. If they don't mind me posting it I'll figure out how to do that and get it up.

Mark does an amazing job, I've got another buddy with 1075's that he rebuilt back stock. Just sea trial time so far, but they run great.

As Merc gets more and more of the 1,100 and 1,350's out there I hope these Merc 850+ motors become more available on the used market.

Looks sweet, may need some new painted cowl covers though.

Should pick up 20 plus with the motors & if you really set it up it should approach 30 MPH.

There's multiple packages, all can start from 850, 1025 or 1075.

The 1330 was the larger SC's, stock valve train. With the upgraded cam package we offer, it makes 1390hp with race gas, 1225 on pump gas.
