    Welcome

    Only Seadoo has the expendable wear ring, as far as I know.

    The Yamaha wear ring has stainless steel surface.

    Does your new jet pump need repair?

    I would recommend buying a copy of the official Yamaha Service manual. This is sold through the GH forum’s online store, in the Yamaha performance section.

    There are a bunch of common upgrades and improvements for the GP1800. They have been documented in various threads on this forum.

    What model year is your GP1800? Yamaha made a few changes from 2017 to 2018, and IIRC a few things also changed for 2019.

    Where are you located and what kinds of water do you ride in? Click in top right of web page to update My Profile with your location.
