Product Details

The Sierra 18-3428-1 is a complete water pump repair kit designed for Yamaha outboard motors. This kit does not include the housing, making it the ideal solution when your existing housing is still in serviceable condition and only the internal wear components need replacement.

Built to marine-grade standards, every component in this kit is engineered for durability and corrosion resistance in demanding saltwater and freshwater environments. The included 6-fin impeller delivers reliable coolant flow to keep your outboard engine running at optimal temperature.

Kit Includes:

  • Water Pump Impeller (18-3069)
  • Water Pump Gasket (18-0240)
  • Water Pump Gasket (18-0756-1)
  • Outer Plate Gasket (18-0757)
  • O-Ring (18-7436)
  • Bolts — 18-0256 (qty. 2)

Key Features:

  • Non-corrosive, marine-grade construction for long service life
  • 6-fin impeller design for consistent coolant circulation
  • Kit without housing — same internal components as Sierra 18-3461
  • Direct OEM replacement for Yamaha parts

Replaces OEM Part Numbers:

Allways been easy to order, quick shipping also.

Great Experience and Awesome website. Affordable price as well

Very easy to shop for the parts that I need and great prices.

All good so far. Could be a little clearer about if the order will include needed any additionally needed hardware for install.

The process seemed pretty simple to me. Will definitely use again.

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier

easy buying. great prices
