Protect the heart of your Yamaha’s cooling system with the Outer Plate, Cartridge (6CE-44323-01-00)—the thin but critical shield that keeps your water-pump impeller happy and your temperature gauge steady.

Cast from Yamaha’s corrosion-proof stainless blend and precision-ground to a mirror finish, this plate sits directly beneath the impeller on F150, F175, and F200 lower units. Its smooth surface reduces friction during every revolution, while the raised lip channels a clean, even stream of water toward the power-head.

Why swap it at every pump service?

• Factory-matched thickness and diameter keep impeller vanes from cupping or walking.

• Polished wear face minimizes heat build-up, extending impeller life in sandy or silty bays.

• Anti-cavitation ports (micro relief slots you can feel with a fingernail) help the pump hold prime at idle.

• Stainless alloy resists pitting and rust far better than aftermarket brass or coated steel copies.

Installation is straightforward: drop the plate over the locating pins, add a dab of Yamalube grease, set the new impeller, and button up. Ten extra minutes during a routine service buys a season of reliable cooling—and the peace of mind that comes from running genuine Yamaha hardware.
