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.

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.

Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.
