COYOTE BOAT

In the quest to top our other crazy builds at Shrader HQ, we decided to venture to the lake waters of Charlotte NC to find the perfect place to do something even more crazy. In Southern California in the 70’s there was a huge movement for stylish low-profile drag boats that featured huge cubic-inch car engines hanging out of a small lightweight hull. And what better way to showcase our Shrader tuning abilities than to build a coyote swapped drag boat monster. The goal was simple. Make it wild, and go big or go home.

We located a nicely painted 1975 Laveycraft V-drive 18′ boat in FL that had a BBC engine. Obviously we had no interest in the heavy carbureted engine, so we yanked that out along with all the wiring and started fresh.

We started with a Gen2 Coyote engine that already features strong internals, then topped it off with a Gen3 intake manifold for high rpm airflow coupled to a Vortech JT supercharger pushing up to 15 psi at 7800 rpm. We upgraded the oil pump gears because those are typical weak links in the coyote, added a front sump oil pan because the engine is backwards in the boat, and then coupled it to the Casale V-drive gearbox that was already in the boat, using some custom engineering.

The Ford Racing control pack takes care of wiring and computer controls, with a custom Shrader calibration made for the water environment it lives in. Kooks Headers took the time to build a one-off custom header design for this boat, that also includes their collector mufflers to reduce noise on the local lakes yet still scream at WOT when the pedal goes to the floor.

With an engine that makes peak torque all the way to 7500+ thanks to the Vortech supercharger, it is the perfect setup for a boat engine! The only word we’ve been able to describe it with after lake runs, is “Sketchy”. Because as you top 100 mph on water at ridiculous acceleration, the only feeling you feel… is Sketchy.
