Product Details

The Sierra 18-3180 is a direct-fit replacement water pump housing designed for Johnson/Evinrude outboard motors. This housing serves as a critical component of the outboard's raw water cooling system, enclosing the impeller and directing water flow through the engine to prevent overheating. It is a direct replacement for OMC OEM part number 435390.

Sierra designs its replacement marine parts to meet or exceed original equipment manufacturer (OEM) specifications, ensuring reliable performance and a proper fit in demanding marine environments.

Key Features:

  • Direct OEM replacement — replaces OMC/Johnson/Evinrude part 435390
  • Meets or exceeds OEM specifications for fit, form, and function
  • Compatible with Johnson/Evinrude 9.9 HP and 15 HP outboard motors
  • Also compatible as part of Sierra water pump kit 18-3327
  • Cross-references: GLM 12460

This housing is commonly replaced during routine water pump service intervals alongside the impeller, wear plate, and seals. It is also included as a component in Sierra's complete water pump repair kit 18-3327.

OEM & Cross-Reference Part Numbers:

  • OMC / Johnson / Evinrude: 435390
  • GLM: 12460
  • Sierra Kit (includes this housing): 18-3327

Quick, easy and accurate!

Price was much lower than any other parts dealer. Even with standard shipping, the parts arrived in a couple of days. Would use autoplicity again. Absolutely no problems.

Good

had the best price on the Internet and free shipping!

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!

Great shopping experience - best price & shipping I could find!

Ordered an ARP ring compressor, best price I could find online, Fast shipping A++
