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.

WEIRD feature - requires a water bottle
Color: Cow, Size: Large
Cute, but buyer beware. Maybe the description said this, but who would think to read for this.... You have to insert an empty bottle (like an old water bottle) for it to make the crinkle noise. There is a velcro spot at the base where you can open it and insert the water bottle for the noise factor and your dogs entertainment. I've yet to do that, but feel like my dog is gonna figure out the velcro and get the bottle out in no time. Seems like a waste of money. I could just give her an empty water bottle without the toy for free.

Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it
