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.

Works but fibers are an issue
Size: 10 Pacck, Color: Multicolor
These were great for my small Yorkie puppy. She had to is bite issue and we needed these tennis balls to help her stretch and correct her jaw. Squeaker works well. The chewing helped but it wasn’t necessarily “chew resistant”. the little fibers from the ball will start to come off and dog will hack a bit. For that reason, I am unsure of the safety of it long term. Must be supervised always. Will try a def brand next time but this helped our lady w her jaw pain/issue.

good for puppys young dogs, handle is separate, locking carabiners on both ends
Color: Orange, Size: 30FT
This is a good sturdy leash but probably wouldn't stand up to a conscientious chewer if your dogo has that bad habit. I like this one because the handle is separate so it can be used both as a tie out lead and as a regular lead. I also like the "locking" carabiners that should not open accidentally. I bought the thirty foot version because my new puppy loves to go outside then refuse to come back in or let me catch him when I need him to come inside (not catching me silly Hooman). When he's bigger I won't be so concerned about him being outside alone but since I'm in a sort of rural area, we have the occasional fox and hawk around when the sun goes down. Not too much to worry about in the way of pests but every puppy parent has an obligation to protect their young'un till they gain some wisdom. I have stairs in the back of the house, the way this is made I can attach it to the banister easily so I don't even need one of those tie stakes that bury in the ground. The price wasn't bad, the hardware looks sturdy and should last awhile. I just also bought the fifteen foot version, same quality as the thirty foot product I like that the handle is separate so it can be used as a tie down or a leash easily. My only big wish would perhaps be some more color choices, the orange is nice for visibility a yellow would be nice and then maybe some other colors like red/purple would be good as well. The thickness of the rope means that it doesn't "easily" get tangled into a giant knot. I leave the back door open and puppers can go in and out as he likes but he also sometimes runs around in the living room and thus far haven't had any large tangles to unwrap. He did manage to get the leash caught around a piece of tree branch that was on the ground (and complained loudly) but that was only because the branch was too heavy for him to drag the lead off of by himself. These leads are worth the money, I will likely buy a couple more to keep in the vehicle and other locations besides home.
