These linkage couplers are designed to get rid of the loose-fitting plastic factory pieces. The OEM stock couplers have so much slop that the front valve always lags the back by almost 10 degrees of movement. Actually, the front valve never fully opens when using the stock couplers.
WaveEater Couplers are tight fitting and use stainless steel pins for proper alignment and synchronization of valve movements, making all the valves fully open and open when they're supposed to. They are held in place with a stainless steel spring and are made from black delrin material.
Instructions:
1. To remove the original couplers, pull the black plastic clip off the power valve shaft. We will not use the black clip when installing WaveEater couplers.
2. Push the coupler forward and pull up and off.
3. Install the new WaveEater CouplerSlide on the small end of the spring, then the stainless washer. The washer keeps the slotted shaft from spreading apart. Push the washer and spring on as far as it will go. Next, angle the coupler and slide on the flat end of the coupler over the long slot in the power valve shaft.
4. Line up the pin with the mating shaft and slide the WaveEater Coupler back into place. This will be a very tight fit and may take a little force to lock into place. The spring holds it on.

⚠️ Warning — Professional Installation Required
• Ensure the hull is fully ventilated and free of fuel vapors before using electric or battery‑powered tools. Failure to do so may result in fire, explosion, serious injury, or death.
• Disconnect the battery before performing any installation or maintenance to prevent accidental ignition, electrical shock, or unintended engine engagement.
• Allow the engine, exhaust, and surrounding components to cool completely before beginning work.
• No smoking, open flames, or spark‑producing devices should be present during installation.
This product is not intended for use on watercraft equipped with pollution‑control systems. Modifying or removing emissions‑related components may violate state or local laws and may render the watercraft illegal for use outside of competition.
