Installation Guide

  1. Safety First: Disconnect the engine's battery and shift the outboard into neutral.
  2. Lower Unit Removal: Remove the bolts securing the lower unit (gearcase) to the engine's midsection and carefully lower it.
  3. Access the Pump: Unscrew the bolts on the water pump housing and lift the housing off.
  4. Component Replacement: Remove the old impeller, gaskets, wear plate, and seals. Note their orientation before removal.
  5. Clean Surfaces: Thoroughly clean the mating surfaces of the housing and gearcase, removing any old gasket material or debris.
  6. Install New Parts: Install the new components from the kit in reverse order. Lightly grease the new impeller and insert it while turning the driveshaft clockwise to bend the vanes correctly.
  7. Reassemble: Reinstall the water pump housing, ensuring the gaskets are aligned. Tighten the bolts to the manufacturer's specified torque.
  8. Final Steps: Reattach the lower unit to the engine. Reconnect the battery and test run the engine in water, confirming a steady stream from the tell-tale port.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?

A: First, check the Compatible Engine Models table in this listing. Verify your engine's brand, model, horsepower, and year range. This kit is a direct replacement for OEM part numbers 69G-W0078-00-00 and 69G-W0078-02-00. Comparing images to your existing part can also help confirm fitment.

Q: How often should I replace the water pump kit?

A: For optimal performance and engine safety, it is recommended to inspect the impeller annually and replace the entire water pump repair kit every 1-2 years or 100-200 hours of use. This interval may be shorter if you frequently operate in sandy, silty, or saltwater environments.

Q: What are the symptoms of a failing water pump?

A: The most common signs include the engine overheating alarm activating, a weak or non-existent water stream from the "tell-tale" outlet port, or steam coming from the exhaust. Upon inspection, a worn impeller may appear cracked, brittle, or have broken vanes.

Q: OEM vs. Aftermarket?

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?

A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.
