I'm parting my boat out after a trailer mishap. Can be heard running in the boat.

A conservative 775HP each. Motors have 220 and 230 hrs. Valve springs done at 150 hrs. The timing belts were done 3 hours ago along with the sea pumps. These motors were religously maintained. Have pre-lubers. so never a dry start. Most of the hours have been below 3000 rpm. It pushed a heavy 36' foot boat to 90 MPH on GPS, turning 31P 18" 4 blade props to SSM3.

-Jesel timing belt assemblies
- Brodix intakes with fuel rails, HAWK throttle body and 72lbs injectors
-Electromotive Fuel Injection and Ignition. Distributorless and fully programmable setup. Have the software, so you can datalog as well. Can change pullies and get more power if desired
-Vortec V4 race blowers with Procharger intercoolers.
-KE 2 piece valve covers
-High torque mini starters
-Gill manifolds and custom riser
-Stewart water pump
-Aeromotive adjustable fuel regulators

I have receipts for most of this as well. Motors were balanced and blue printed.
