Installation Guide

  1. Disconnect the negative battery cable and shift the outboard into the neutral position.
  2. Remove the lower unit (gearcase) by unfastening the bolts that connect it to the engine's midsection. You may also need to disconnect the speedometer tube and shift linkage.
  3. With the lower unit on a suitable workbench, remove the bolts securing the water pump housing cover.
  4. Carefully lift the old water pump housing, impeller, and wear plate off the driveshaft, observing the orientation of the impeller vanes.
  5. Thoroughly clean the driveshaft and the housing mounting surface, ensuring all old gasket material and debris are removed.
  6. Install the new gaskets, wear plate, and driveshaft key included in the kit.
  7. Slide the new impeller onto the driveshaft. While turning the driveshaft clockwise, lower the new housing over the impeller to correctly seat the vanes.
  8. Press the housing down firmly and tighten the bolts to the manufacturer-specified torque.
  9. Reinstall the lower unit, carefully aligning the driveshaft, water tube, and shift shaft before securing it.
  10. Reconnect the battery and test the engine with a reliable water source (like flushing muffs) to confirm proper water flow from the telltale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Mercury engine?
A: Verify your engine's serial number. This kit is made for 75-115 HP 4-stroke models with serial numbers 2B094996 and up, and 150 HP EFI models with serials 1B905505 and up. You should also cross-reference your existing part number with 8M0094529, 8M0094259, or 8M0057715 to ensure a match.

Q: What are the signs my water pump is failing and needs replacement?
A: Key symptoms include your engine overheating at idle or low speeds, a weak or inconsistent water stream from the "telltale" outlet, or discovering the impeller is brittle, cracked, or has missing vanes during a routine inspection.

Q: How often should the water pump impeller be replaced?
A: As part of preventative maintenance, we recommend inspecting and replacing the water pump impeller and gaskets every 100 operating hours or annually, whichever comes first, even with low usage.

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.

Q: How fast do you ship and how much does it cost?
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.

Size up

I had another pair of a different style from the same seller that shrunk when left in the sun. That one wasn't available anymore, so I bought this one in the same size, and they are too small. They are comfy shoes but not true to size

I ordered these after having knee surgery and they’ve been a god send. I wear them around the house and they help so much with knee pain. They’re great quality and sized as expected.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
