Upgrade & Re-Power

About Our Engines

Whether you’re repowering tired engines in a commercial vessel, pleasure boat, or just want
to go faster more reliably, the answer is our 7.3L Marine Godzilla Engines. Compared to
the widely applied Merc 454’s & 496’s you can gain a substantial increase in power at a
fraction of the weight, gaining speed from both improvements. Near 300lbs per motor savings! In
the case of Mercury’s HP500’s and other blue motors, no one likes top end or whole
engine overhauls. We know that valve train stress is the number one factor in marine
engine overhaul intervals. Repower and enjoy extended service intervals making the same
power at a fraction of the valvetain stress with Marine Godzilla Engines. Check out the
power produced vs valve lift and duration in the specs below. See our FAQ’s page for
swap, repower, and in depth integration details of our packages.
