Installation Guide

Professional installation is recommended. The following are general steps for reference:

  1. Safety First: Disconnect the battery and remove the spark plug wire.
  2. Position the Engine: Place the engine in a secure, upright position.
  3. Drain Gear Lube: Open the drain and vent screws on the lower unit to drain the gearcase oil.
  4. Remove Lower Unit: Unbolt the lower unit (gearcase) from the upper engine housing. This may require disconnecting the shift linkage.
  5. Access Water Pump: With the lower unit removed, unbolt and lift the water pump housing to expose the impeller and other components.
  6. Inspect & Replace: Remove the old impeller, plate, cup, and seals. Clean all surfaces thoroughly.
  7. Install New Parts: Install the new components from the kit in the reverse order of removal. Ensure the impeller vanes are oriented correctly.
  8. Reassemble: Re-install the water pump housing, followed by the lower unit. Reconnect any shift linkage.
  9. Refill & Test: Refill the gearcase with fresh lubricant. Start the engine in a test tank or with a water flusher to confirm a strong water stream from the tell-tale outlet.

Troubleshooting & FAQ

How do I confirm this kit fits my Mercury 2 HP engine?

First, verify your engine is a Model 2A or 2B manufactured between 1984 and 2002. Second, check that your existing part number matches one of the direct replacements listed in our cross-reference table, such as Mercury 46-6885M or 46-80395M.

What are the signs that my water pump needs to be replaced?

Common signs of a failing water pump include the engine overheating, a weak or non-existent stream of water from the "telltale" outlet, or finding a brittle, cracked, or damaged impeller during a routine inspection.

How often should I replace the water pump impeller?

For preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use. Replacement frequency should be increased if operating primarily in saltwater or sandy/silty conditions.

Poop bag and treat dispenser questionable
Color: 9 Pack (No-stuffed Fox)
This is a hard one. The toys seem great. The whole box smells of the poop bags and I don't think they should be a part of the purchase. The bigger issue i see is the treat ball seems to have a weird plastic coating on it. Almost like a thin clear coat that gives is a peeling feeling and I don't think it is safe for the puppy. Excited to see how she likes the other toys though.

WORTH EVERY PENNY
Style: S-Level 2, Style: S-Level 2
I’m really happy with this interactive dog treat puzzle. It keeps my dog engaged, challenged, and excited, especially when he needs something to help burn off mental energy. The compartments are easy to fill with treats, and it was fun watching him figure out how to move everything around to get the rewards. It seems well made and has held up nicely so far. I also like that it slows him down a bit and gives him something productive to focus on. This is a great option for keeping dogs entertained, reducing boredom, and giving them a little mental workout. Overall, I would definitely recommend this to other dog owners looking for a fun and stimulating treat toy.

My Dog Likes It… But My Cat LOVES It!
Style: S-Level 2
⭐⭐⭐⭐⭐ I originally bought this puzzle feeder for my dog, but surprisingly, my cat became obsessed with it! She has been using it since she was very young and figured it out incredibly fast. I love that it turns treat time into a fun mental challenge. Instead of simply giving treats between meals, it encourages problem-solving, movement, and natural foraging behaviors. It’s a great way to provide enrichment, keep them entertained, and stimulate their minds while rewarding them at the same time. The different compartments and sliding pieces keep things interesting, and it’s been durable enough to handle daily use. Watching my pets learn and interact with it is honestly one of my favorite things. If you’re looking for a way to keep your dog or cat mentally engaged while offering treats in moderation, I highly recommend it! 🐾 A great enrichment toy that makes snack time more rewarding and interactive.

Durable interactive fun for You and your Dog
Style: S-Level 2
It’s it’s an interactive toy if your dog isn’t lazy like my little boy. He likes to play, but he wants me to show him where everything is. It’s very doable because he’s rough and tough and it was much more reasonable than some of the other interactive toys..
