Jet Pump Housing for Yamaha 242 LTD E-Series 1800 2016 Boat

Jet Pump Housing for Yamaha

This jet pump housing is the replacement housing component that holds and aligns the impeller assembly for Yamaha 242 LTD E-Series 1800 jet boats from 2016, keeping water flow directed through the pump for consistent thrust.

Overview

This jet pump housing is a direct-fit replacement component for the Yamaha 242 LTD E-Series 1800, giving the pump a solid, properly aligned home for the impeller and wear ring. It is built for boat owners and marine mechanics who need to replace a cracked, corroded, or worn housing without replacing the entire pump assembly. The jet pump housing restores proper clearances so the pump can move water efficiently again.

Specs At A Glance

Good To Know

Q: Do I need to replace the wear ring at the same time? A: It is worth inspecting the wear ring and impeller while the housing is off, since a scored ring can cause cavitation even with a new housing.

Q: Will this housing fit both pumps on my boat? A: These boats run twin pumps, so confirm which side you are servicing and check the part number against your serial number before ordering.

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