Dave bush the OMC guru builder can make well over 400 hp on pump gas.."
Mine was detuned to 450 from 470 on Chevron 91 octane. This engine was on my XB2003. I finally made a trim system that should work. It's apart now in AZ being freshened up and a couple tweaks. Then put on the dyno and remapped, with the knowledge he has gained in the last 2 years. Dave has mentioned going after the outboard record.
This is from Jasper a couple of years ago....
