Questions & Answers

Is this a genuine Tohatsu part?

This is a premium quality replacement kit manufactured to exceed original equipment (OE) specifications, specifically designed for the UK marine market by 4boats.co.uk suppliers.

How often should I replace this kit?

We recommend inspecting the impeller and gaskets every 100 hours or once per year. Rubber components can become brittle over winter storage.

Does this kit include the metal wear plate?

No, this is the Service Kit which includes the impeller, gaskets, and key. If your wear plate or housing is scored, you may require a full "Repair Kit" (MPN 369-87322-0).

Note: Please verify your original part number or engine serial number against the fitment guide above before purchasing to ensure 100% compatibility.
