Wax Racing Cable Throttle Conversion Bracket

Sea-Doo Spark • 1503 4-TEC • 1630 ACE

Convert your drive-by-wire Sea-Doo engine to a traditional cable-operated throttle.

If you're installing a Sea-Doo Spark, 1503 4-TEC, or 1630 ACE engine into a custom watercraft, jet boat, race ski, hovercraft, buggy, or any other project, one of the biggest challenges is dealing with the factory electronic throttle system.

The Wax Racing Cable Throttle Conversion Bracket solves that problem.

This billet bracket securely mounts the factory throttle position sensor (TPS) while allowing the use of a conventional throttle cable. The result is a simple, reliable, and compact throttle solution that's perfect for engine conversions where retaining the original electronic throttle body is impractical.

Why Use a Cable Throttle?

Many custom projects don't have the space, wiring, or ECU strategy to support the factory electronic throttle pedal and associated control systems.

Our bracket allows you to:

✔ Use a standard throttle cable
✔ Retain accurate TPS feedback to the ECU
✔ Simplify engine conversions
✔ Eliminate bulky electronic pedal assemblies
✔ Create a cleaner and more reliable installation

Whether you're building a race ski, jet boat, custom watercraft, or off-road project, this bracket makes integrating modern Sea-Doo powerplants significantly easier.
