Jet Pump Housing for Yamaha

This jet pump housing is the stationary housing that holds the impeller and wear ring on Yamaha 1800 series jet drives, giving the pump its wear surface and mounting structure for the 2010-2019 SX 240 HO.

Overview

This jet pump housing for Yamaha fits the 1800 engine platform used across the 2010-2019 SX 240 HO run.

Designed for owners doing their own pump service or rebuilds.

Specs At A Glance

Good To Know

Q: Will this housing fit my 2015 SX 240 HO? A: It is intended for the 1800 series SX 240 HO built between 2010 and 2019, but confirm your serial number and pump assembly before ordering.

Q: Do I need new wear ring or impeller hardware with it? A: It is good practice to inspect the wear ring, impeller, and seals while the pump is apart so you can replace anything worn at the same time.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
