Yes, This Is A 1,000hp Coyote-Swapped Speed Boat!
Shrader Performance has a unique use for a Coyote with 750 lb-ft of torque and crazy headers
When Ford introduced the Coyote platform, builders immediately began finding swaps. By now, we’ve seen plenty Coyotes in Fox Bodies, Cobra kit cars, early Ford trucks, or even Chevys, but we never imagined a Coyote on the open water. Steve Shrader of Shrader Performance, a Ford performance shop who specializes in making big power, decided to drop a specially-built, 1,000hp 5.0L Coyote into a speed boat, nicknamed The Riddler.
Shrader purposely built this Gen2 Coyote for a speed boat. “This is a proven package for us, and it works really well,” said Shrader. They have the same engine setup in a 2015 ROUSH Stage 2 Mustang, which makes 849 hp to the wheels. “We’ve had such great results from the S550’s Coyote platform and Vortech (V-7 JT). I immediately knew this was the combo I wanted. The boat is meant to show what the Coyote platform is capable of.”
The team started with a Ford Performance Gen2 Coyote that features a forged crank. It’s topped with a GT350 intake manifold, and then a Vortech JT supercharger blowing through an air-to-air intercooler. Shrader likes the GT350 intake as it has the required high rpm airflow for the supercharger. The Vortech features a 3.33 pulley and pushes 16 psi at 7,800 rpm. The oil pump gear and crank gear were replaced with forged gears. A Ford Performance control pack takes care of computer duties, with a custom tune by Shrader specially designed to handle the power delivery suited for water.
The wild headers were custom built by Kooks Headers, with 2-inch primary piping into 3.5-inch collector mufflers. Unlike other marine cooling systems, the Coyote’s is self-contained using a radiator from a ‘60s-model Austin Cooper. It also means the boat can run in the garage without worry of overheating, just maybe complaints from the neighbors.
Auto Meter gauges tell the driver what’s going on, with a large tach, oil pressure and water temp gauges. The traditional foot pedal took some custom engineering to work with the Coyote electronics, but it was a must-have for the boat.
Shrader had the engine complete, but no boat yet, so he searched the eastern seaboard for a suitable home. He found this 1975 Lavey Craft in Florida complete with fresh paint, “These boats are hard to find on the east coast since this was a Southern California craze in the ’70s,” said Shrader. The boat had a 498ci big-block Chevy when purchased, “Obviously we had no interest in the outdated, heavy, dinosaur engine, so we yanked that out along with the wiring, and started fresh.”
The engine sits backwards in the boat, so Shrader had to install a Canton front-sump oil pan. The Coyote is backed by a T45 Mustang bell housing with 2003 Cobra aluminum flywheel. A Casale V-Drive points the power towards a D21 Prop Shaft and a custom-built 3-blade LH prop from Hill Marine.
Is there reverse on the boat? “Yeah, it’s two wooden paddles under the passenger seat.”
