Yamaha Diaphragm, Pump - 6R7-14541-00-00

Overview

The Yamaha Diaphragm, Pump, part number 6R7-14541-00-00, is an OEM replacement or service component for compatible Yamaha WaveRunner and boat models. The fitment table below covers 44 model/application entries spanning model years 1990-2016. Fitment includes Exciter 135, Exciter Single, Exciter and other compatible applications.

This genuine Yamaha sealing component is designed for the factory-specified sealing point on compatible models. Gaskets, O-rings, seals, packings, and diaphragms are commonly replaced when disturbed, worn, hardened, cut, or leaking during service.

A diaphragm might seem like a small piece, but it’s doing a lot of work every time the engine runs. I’ve seen engines struggle to stay running or lose power just because this part got stiff or worn out. When it’s fresh and flexible, fuel delivery stays consistent and the motor responds the way it should. It’s one of those maintenance items you don’t want to overlook.
