Product Details

The Sierra 18-3411 is a complete water pump kit with housing designed for Yamaha 9.9 HP and 15 HP outboard motors. This all-inclusive kit provides everything needed to restore proper cooling system function and protect your engine from overheating. It is a direct replacement for several Yamaha OEM part numbers as well as the Mallory equivalent, ensuring a precise fit.

Key Features:

  • Complete kit with housing — includes the water pump housing, impeller, gaskets, and all necessary hardware for a full rebuild
  • 6-pin impeller — designed specifically for Yamaha small outboard cooling systems
  • Durable, marine-grade construction — non-corrosive components built to withstand harsh saltwater and freshwater environments
  • Assembled in the USA — manufactured in Sierra's Illinois facility to meet or exceed OEM specifications
  • Same as Sierra 18-3148 but includes the water pump housing for a complete service solution
  • Covered under Sierra's industry-leading customer satisfaction warranty

Replaces OEM Part Numbers:

  • Yamaha: 682-W0078-00-00, 682-W0078-01-00, 682-W0078-A1-00, 682-44300-01-00
  • Mallory: 9-48600, 9-48605

Sierra water pump kits are a trusted choice for marine mechanics and boaters alike. Regular water pump service is essential to maintaining engine cooling efficiency, and the Sierra 18-3411 makes it easy to perform a thorough, complete rebuild with confidence.

Thanks

I called to see if it would ship before I needed it to go on a trip. I gave bad information about my order, but the employee went out of his way to track down my order and made sure that it went out ASAP. Thanks guys!!!<br><br>

easy thanks

Great prices

Great price and fast shipping.

good customer service. after shopping around for a while i decided to go with them.

Order 18232. Everything came quicker than expected! Packed well and in excellent condition. Definitely recommended. Already did to one of my friends looking for parts.

So far, so good. Best price I found. Very reasonable shipping. Parts were loose packed and rattled around a bit but nothing damaged. The hole for the EGR in the header was just a small hole and I had to drill it out. There were no instructions or any do

Easy site to use and order from. Autoplicity has friendly customer service and also they had the CHEAPEST price on the exhaust tip that I ordered for my truck. I am a very happy customer!!!

Smooth process and easy to follow instructions for checkout

fast and easy ordering process.

good price fast shipping
