Installation Guide

  1. Disconnect the battery and shift the outboard gear into neutral.
  2. Remove the lower unit (gearcase) by unbolting it from the engine's mid-section.
  3. Locate and unbolt the water pump housing to access the old impeller.
  4. Carefully remove the old impeller, key, gaskets, and wear plate. Clean all mating surfaces thoroughly.
  5. Install the new lower gasket and stainless steel wear plate onto the pump base.
  6. Insert the new impeller key into the slot on the driveshaft.
  7. Slide the new impeller onto the driveshaft. Rotate the driveshaft clockwise while pushing down to seat the impeller vanes correctly inside the housing.
  8. Install the new upper gasket, seals, and O-rings onto the pump housing.
  9. Secure the pump housing with the bolts, tightening them to the manufacturer-specified torque in a crisscross pattern.
  10. Reinstall the lower unit, making sure the driveshaft, shift shaft, and water tube are correctly aligned.
  11. Reconnect the battery. Start the engine in a suitable water source and immediately check for a steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this impeller kit fits my Mercury engine?

A: The most critical step is to verify your lower unit's torpedo diameter is 3.44 inches (87.38mm). This kit is often confused with others for similar HP engines. Cross-reference the OEM part numbers listed and check the serial number ranges in our compatibility table to ensure a perfect match.

Q: What are the signs my water pump impeller needs replacement?

A: Common signs that your impeller is failing include a weak or non-existent water stream from the "tell-tale" pisser port, a steadily rising engine temperature gauge at idle or low speeds, or a low water pressure alarm if your engine is equipped with one.

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

A: For preventative maintenance, it is recommended to inspect and/or replace your water pump impeller every 100-200 operating hours or at least once per season, whichever comes first. This helps prevent overheating and costly engine damage.

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.

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.

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.

Good, Cheap Makeup Wipes
Scent: Fragrance Free, Size: 25 Count (Pack of 1)
These wipes are a great value for the price and remove my everyday makeup—SPF, eyeliner, mascara, and lip products—without irritating my skin. They work efficiently and don’t require harsh rubbing. Compared to similar options, these are a better deal, and I plan to repurchase.

More Than Just a Wipe – A Small Miracle in a Plastic Pack
Scent: Fragrance Free, Size: 25 Count (Pack of 1)
Let me take you back to a Tuesday night, 11:43 PM. I was exhausted. I had just finished another long day juggling work, a messy kitchen, a toddler who refuses to sleep unless I sing “The Wheels on the Bus” four times, and a dog that mysteriously smells like pickles. I stumbled into the bathroom, glanced at my reflection in the mirror, and winced. Smudged eyeliner. Patchy foundation. That faint trace of mascara that somehow survived an entire day, a meltdown, and an unexpected rainstorm. I had zero energy left. The thought of going through my full skincare routine felt like climbing a mountain. But then I remembered the Amazon Basics Makeup Remover Wipes sitting under my sink. I pulled one out and noticed right away how soft and thick the wipe was—not papery or overly soaked like others I’ve used. It felt gentle. Almost comforting. I held it against my face for a few seconds and, without rubbing, it just… did its job. Mascara? Gone. Eyeliner? Gently wiped away. Foundation, oil, and even the invisible layer of "today was too much"? All off, effortlessly. What surprised me even more was how hydrated and fresh my face felt afterward. No tightness, no weird film, no dry patches. Just clean, calm skin. And the best part? Absolutely no scent. As someone with sensitive skin and a nose that notices everything, I deeply appreciate the fragrance-free formula. It’s rare to find a product that truly feels like it respects your skin instead of overpowering it. Since that night, these wipes have earned a permanent spot in my routine. Not just for makeup removal either. I’ve used them on groggy mornings when I don’t want to splash cold water on my face, after a sweaty walk, or to fix smudged eyeliner when I’m in a rush. They’ve even come with me on road trips and tucked inside my hospital bag when I gave birth. Each resealable pack keeps the wipes moist and fresh, and the fact that they're plant-based with FSC-certified fibers? That made me feel even better about my nightly ritual. And six packs? That’s months of clean, makeup-free evenings without ever needing to reorder. Sometimes it’s the small things that save the day. For me, it was a simple, fragrance-free wipe that helped me feel human again after the chaos. And I’ll keep buying them because they never let me down.

Great makeup wipes, noticed a tiny bit of irritation.
Scent: Hydrating, Size: 25 Count (Pack of 2)
These makeup wipes are great! They easily get off my makeup whether it be gel based liners, lipstick, mascara, eyeliner or waterproof makeup. I find one wipe is more than absorbent enough to take off all my makeup and I often use the rest to clean off my brushes; although I don’t usually wear a full face, just a mixture blush, lips, brows, highlighter, and always eyes. I find that the cloth is nonabrasive. The only issues I have with it is that the packaging is impossible to stay closed so I bet that may dry out the wipes over time. I also find that especially around my eyes I see redness and dryness after wiping and it needs a couple of wipes to get everything out of my lashes. The redness goes away after a couple minutes, but as someone with sensitive skin I get worried especially as I have had other sensitive makeup wipes not have this issue. Luckily I haven’t broke out, haven’t had lasting dryness, or issues from this product. Works well!

Fragrance-Free & Works So Well!
Scent: Formulated without Fragrance, Size: 25 Count (Pack of 2), Scent: Formulated without Fragrance, Size: 25 Count (Pack of 2)
These are great for the price! I only use makeup removers that are fragrance-free, so I really appreciate that about these. My face feels clean and refreshed after using them. I usually only need 1–2 wipes per night along with my face wash, so they feel pretty durable to me. I also have sensitive skin, and even some fragrance-free wipes can irritate it, but these don’t seem to cause any irritation at all so I guess the ingredients are just right for me. They remove my makeup really easily!

Love these! Bought the night calming ones and honestly the're the best ones I've ever tried. I have sensitive skin and other "sensitive skin ones" leave my skin burning and red. But these are extremely soft, leaves my skin so soft and moist. And a super plus, gets rid of my waterproof mascara in one wipe!
