Installation Guide

  1. Disconnect Power: Start by disconnecting the battery.
  2. Drain Gear Lube: Drain the gear lube from the lower unit to prevent spills.
  3. Remove Lower Unit: Unbolt and carefully detach the lower unit (gearcase) from the outboard's main housing.
  4. Access Pump: Unscrew the bolts holding the water pump housing and remove it to expose the impeller.
  5. Inspect & Remove Old Parts: Note the rotational direction of the old impeller's blades before removing it, along with the housing, plate, cup, and gaskets.
  6. Clean Surfaces: Thoroughly clean all mating surfaces to ensure a proper seal with the new components.
  7. Install New Components: Install the new gasket, wear plate, insert cup, and woodruff key.
  8. Install New Impeller: Slide the new impeller onto the driveshaft, twisting it in the same direction as the original to correctly seat the vanes.
  9. Reassemble Pump: Apply the new O-ring, reinstall the housing cover, and tighten the bolts to the specified torque.
  10. Reattach Lower Unit: Reinstall the lower unit onto the outboard and refill it with fresh gear lube.
  11. Test Operation: Before heading out, connect a water supply (flushing muffs) to the engine, start it, and confirm a steady stream from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?

A: First, check your engine model, horsepower, and year against the detailed compatibility table above. For Yamaha owners, use the linked Serial Number Guide to find your exact model information. This kit directly replaces OEM part numbers 63D-W0078-00-00 and 63D-W0078-01-00; cross-referencing this number is the most reliable way to ensure a match.

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

A: For optimal engine protection, we recommend inspecting the impeller annually. It should be replaced every 1-2 years or every 100-200 hours of use. Replacement frequency depends on operating conditions; engines used in saltwater or sandy/silty water may require more frequent service.

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

A: The most common signs include the engine running hotter than normal or an overheating alarm, a weak or non-existent water stream from the "tell-tale" cooling outlet, and steam from the exhaust. During inspection, a damaged impeller may have brittle, cracked, or melted 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.

Q: What is your warranty and return policy?

A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.

The Quality of the sheepskin is awesome.
Color: Wolf Tip, Size: 2' x 3' (Natural)
This rug is a beautiful specimen of New Zealand sheep. The rug is very very soft, the rug is thick, and the brown tips are fabulous looking. All in all I'm very pleased with this purchase. The size is perfect as it measures 2' x 3'. I would buy again from this seller.

Plush rug that’s super soft. WOW!
Color: Natural (Yellow-white Ivory), Size: 6' x 7' (Natural)
Beautiful and super plush! I use it as an outer blanket when cold weather camping. Like a modern day cave man. One of my favorite purchases. I avoid kneeling on it while it’s on my mattress fearing it might split the hide, or damage the stitching. It fits my queen size camper bed. Cant say enough!

Big Investment for a Lifetime of Quality
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Several reviews mentioned a smell lingering with the sheepskin even after being unpacked a few days. I did notice the smell when I unpacked it, but I would expect a slight odor from such an item. It was not overpowering and is completely gone after one month of having it laid out on a chest in our bedroom. It is very functional, can be sat on, knelt on, etc, but is easily brushed off and looks great! The quality is very good…someone in my family is on it every night, and we have experienced no shedding whatsoever. Although the price is a big investment initially, I believe the quality is worthy. We plan to enjoy this beautiful sheepskin for a lifetime!

Love it, but terrible smell at first
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Really soft & my dog loves it. I used it as a throw over my couch for decor. The smell when I took it out of the package was probably one of the worst smells I’ve ever smelled. Like old broccoli or something. I left it outside to air out all day and that was gone.
