WCOT Yamaha SuperJet Intake Grate for 2021+ - SJ4R
This Yamaha SuperJet intake grate is a handling and hook-up upgrade for 2021-2027 SuperJet models. It is built to improve water feed to the pump, help the ski stay planted in rougher conditions, and add better off-throttle braking than the stock setup. The cast aluminum design is aimed at riders who want more control in chop and a more predictable feel in corners and decel. It also carries a claimed 1.5 MPH gain over the stock intake.
On the current SuperJet platform, one of the common complaints with the stock intake is inconsistent hook-up when the water gets rough or when the ski is loaded hard in turns. The SJ4R addresses that with a double scoop layout that helps the pump stay fed more consistently. That means better traction coming out of turns, a steadier ride when the water is not flat, and improved control when you let off the throttle. For riders who want a ski that feels more connected to the water, this is one of the first hull parts to look at.
The cast aluminum body is built for repeated use and gives you a more durable part than a light-duty stamped piece. On a stand-up ski, intake grate choice affects more than straight-line speed. It changes how the ski tracks, how cleanly the pump stays loaded, and how the hull reacts when you back off the throttle entering a turn. That is why riders looking for a more planted feel often start with the grate before moving on to other pump or hull parts.
Installation is straightforward, but 2023+ models may require hole modifications for proper fitment. Use threadlocker during install. Does not fit models not listed below.
