Installation Guide

  2. Remove the lower unit (gearcase) from the outboard motor. Refer to your service manual for specific instructions.
  3. Unbolt and carefully lift the old water pump housing off the driveshaft.
  4. Remove the old impeller, wear plate, key, and any remaining gaskets. Take note of their orientation.
  5. Thoroughly clean the mating surfaces of the gearcase and the driveshaft.
  6. Install the new gasket and face plate onto the gearcase.
  7. Slide the new impeller key into the slot on the driveshaft.
  8. Lubricate the new impeller with a marine-safe lubricant and install it onto the driveshaft, turning the shaft clockwise to bend the vanes correctly.
  9. Lubricate the inside of the new pump housing and slide it down over the impeller.
  10. Secure the new housing with the provided bolts and washers, tightening them to the manufacturer's specified torque.
  11. Reinstall the lower unit onto the outboard, ensuring the driveshaft and water tube are correctly aligned.
  12. Reconnect the battery, start the engine in a water source, and verify a strong, consistent water stream from the engine's tell-tale outlet.

Troubleshooting & FAQ

How do I confirm this kit fits my specific engine model?
Check the "Compatible Engine Models" table. For Mercury and Mariner engines, it is crucial to match your engine's serial number with the ranges listed in the "Notes" column. When in doubt, compare the product photos and part numbers to your old parts before ordering.

What are the signs that my water pump needs to be replaced?
Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or visible damage such as cracked, stiff, or brittle vanes on the old impeller upon inspection.

How often should the water pump impeller be replaced?
For preventative maintenance, it is highly recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of operation. Replacement frequency depends on usage conditions, especially in saltwater or silt-heavy water.

Great for my tidy mind. Now the cabinet is organized and clean. Space saving too
Size: Left Facing, Size: Left Facing
Easy install. Glides nicely holds the jars without much movement. The labels are wonderful. I am super pleased. We bought 4 left facing for our cabinet. Not done replacing all the jars and such. But you can see a good idea how it will be. The fit out needs perfectly and looks great. I really like how neat and good visibility too. They seem sturdy with all the weight of the filled bottles also.

Great space saver, keeps everything organized.
Size: Left Facing, Size: Left Facing
I am soooo happy with this purchase! I’ve been researching lots of spice racks to see which ones would best suit my needs. This definitely fits the bill. This product was perfect. It includes everything you need to organize your spices: the rack, screws, stickers, bottles, and a white gel pen to write additional spice names. The rack is heavy duty and sturdy. Once anchored to your cabinet, there’s no way it’s falling out. The bottles are a good size and you can transfer standard store bought spices directly into the bottles. An additional asset is that the bottles come with a shaker spout that has two options for use. It can easily snap off and on when refilling. The stickers are well thought out. They’re good quality labels and can easily be repositioned. I accidentally had an edge stick to the middle of a bottle and was scared that it wouldn’t come off. I was happy that it lifted up cleanly and didn’t wrinkle the sticker. I didn’t have a need to write a lot of new names, except for two so far. Using the pen included, I wrote labels for Dashi and Seasoning-Arrachera. I tried to match the font of the labels and I think I did a pretty good job. You wouldn’t notice it was hand written unless you really stared at it. The white pen is great and so easy to write with. I didn’t have to go over any letters. One pen stroke was enough. It also came with labels that you can place on the side of the rack for easy identification. I haven’t put them on mine yet because I still need to buy two more racks to store all my spices. Then I can get them all organized the way I want. This is such a space saver. One of my absolute favorite purchases!

Absolutely worth the money!
Size: Left Facing, Size: Left Facing
I can't say enough about these spice racks! I have kept my spices in a corner cabinet on lazy Susans for the last 25 years and that's worked great, but it did not have much curb appeal and some spices were in the middle of the caddies so I would have to pull the front ones off to get to the middle ones. Corner cabinets are tricky and can be such a waste of space, but I made it work. But now it doesn't just work, it sings! My husband bought me 4 units and they fit perfectly in the space. Whoever designed these racks thought through EVERYTHING. The labels are well organized with plenty of obscure herbs and spices as well as all the common ones, and some blank stickers for the products they don't have labels for. There is a list of all the spices and which page you will find the label. There are also small corresponding labels to put on the ends so you know which rack has your spice (I haven't put those on yet because I want to make sure I have everything where I want it first). Since I have 4 sets of labels, I used some for labeling the baskets where I have the extra spices for refills. The racks are sturdy and easy to install. These would also work well in cabinets that are not corners - you would pull them straight out and it would make it easy to access all of your spices. If I could give this 10 stars, I would.

Fabulous!
Size: Left Facing, Size: Left Facing
I wish I had remembered to take a picture before I emptied my spice cabinet. Actually, on second thought, it would be embarrassing to share. I have two of these sturdy slide-out spice racks and could use another one. The racks were not hard to install, slide smoothly, look great, and my spices are in order! I was able to fit two of them on one side of my cabinet. I love the jars and labels. I use some spices much more than others so I put the matching labels on the large containers of these spices and keep them on the top shelf. I would definitely buy these again!

Clever Space Saver with a Few Caveats
Size: Left Facing
This spice rack system really helped bring order to the chaos in my cabinet, and it looks great doing it. The vertical design makes spices visible and accessible, and the included 20 jars and 801 labels are a huge bonus for customization. 🧩 Easy to Install, But Drawer Direction Matters Setup is fairly simple, but take note: the drawer only slides out in one direction depending on which version you buy (left or right facing). As a reviewer noted on page 6, it’s not reversible, which can be a headache if your layout changes or you order the wrong orientation. 🪛 Build Quality is Solid but Assembly Could Be Smoother The frame is sturdy and feels well-made, but you’ll need to screw the rails into the base — and the screws included aren’t the best. One user suggested bolts instead of screws (page 6), and I agree. A little more care here would elevate the overall experience. 🌶️ Jars and Labels Are Fantastic This is where the system really shines. The jars are glass with metal lids and fit perfectly in the rack. The label set includes multiples in several fonts, blank ones, and even a chalk marker — very thoughtful! ✅ Pros: Excellent use of vertical space for spice organization Looks polished and professional in any cabinet Tons of labels and customization options ❌ Cons: Drawer slide direction is fixed — not reversible Screw quality is mediocre Installation requires precision (and patience) Overall: This is a well-designed and space-saving spice rack that delivers on organization and aesthetic. If you're mindful of the fixed drawer direction and take your time during install, it's a great buy for transforming messy cabinets into a neat, labeled setup.
