Description
The Watercraft Werks conversion billet e-box for Kawasaki 550 and 750 hull combinations is designed for builders who are swapping 750 electronics into a 550-based ski and want a clean, secure electrical solution. Rather than improvising mounts or modifying a stock box, this billet aluminum enclosure is made to accept Kawasaki 750 electronics and then bolt into the original 550 e-box mounting location. The result is a conversion that looks intentional and holds up to the demands of aggressive riding.
- Billet aluminum electrical box designed for Kawasaki 550/750 hull conversion setups.
- Allows you to mount Kawasaki 750 electronics inside and then install the e-box in the stock 550 e-box position.
- Supplied in an unfinished state so you can polish it for a raw metal look or send it out for custom anodizing.
- Some anodized e-boxes may be available, with in-stock colors varying over time.
This conversion e-box comes equipped with the hardware and fittings needed to assemble a proper, watertight electrical enclosure. Included are stainless steel hardware for corrosion resistance, five billet Delrin e-box fittings, five o-rings, a billet Delrin cap, and o-ring material to seal the two halves of the box. Electronics are not included, so you will install your own 750 ignition and related components into the enclosure.
- Billet construction provides strength and durability for harsh use in surf, freeride, or recreational riding.
- Stainless steel hardware resists rust and keeps fasteners looking clean even after time on the water.
- Delrin fittings and cap help provide reliable sealing and clean cable transitions into and out of the e-box.
- O-ring seals between the halves are designed to help keep water out and protect sensitive electronics.
- Finished installations can be polished or anodized to match the look of your custom build.
For riders performing 550 to 750 conversions, this e-box simplifies mounting and protects the heart of your electrical system. It combines a professional appearance with a practical, purpose-built design so your converted ski can be both reliable and visually impressive.
