Installation Guide

Professional installation is recommended. The general steps are as follows:

  1. Safety First: Disconnect the battery and ensure the engine is securely mounted.
  2. Drain Gearcase Oil: Place a drain pan under the lower unit and remove the drain/fill screws to drain the gear oil.
  3. Remove Lower Unit: Unbolt the lower unit (gearcase) from the upper engine housing. This may require disconnecting the shift linkage.
  4. Disassemble Water Pump: With the lower unit removed, unbolt and remove the existing water pump housing to access the impeller.
  5. Inspect & Clean: Clean the pump base and housing surfaces, removing any old gasket material or debris. Inspect for scoring or damage.
  6. Install New Parts: Install the new gaskets, faceplate, impeller (ensure the key is in place), and housing from the kit. Lightly grease the interior of the housing.
  7. Reassemble: Reinstall the water pump housing, ensuring bolts are tightened to the manufacturer's specified torque.
  8. Reattach Lower Unit: Reconnect the shift linkage and bolt the lower unit back onto the engine.
  9. Refill Gearcase: Fill the gearcase with the correct type and amount of new gear oil.
  10. Test Operation: Reconnect the battery. Start the engine using a water supply (flushing muffs) and check for a steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

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

A: The best way is to verify your engine's model, year, and serial number against the compatibility tables on this page. Also, cross-reference your existing part number with those listed in our "Part Number Cross-Reference" section. If you are unsure, please contact our support team with your engine details before ordering.

Q: What are the common signs that a water pump or impeller needs to be replaced?

A: The most common signs include the engine overheating at idle or low speeds, and a weak or non-existent stream of water from the "tell-tale" outlet. We recommend replacing the impeller as part of regular preventative maintenance every 1-2 years, depending on usage.

Q: Is there a difference between the 3-cylinder and 4-cylinder versions for the 40-60 HP models?

A: Yes, there can be differences in the gearcase and other components. This kit is specified to fit both, but it's crucial to check your engine's serial number and original part number to ensure this is the correct kit for your configuration, especially with BIGFOOT models which have a different gearcase.

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.

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.

Q: What is your warranty and return policy?

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. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable. They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace. Gets or picks up dirt a bit, but cleans well, except the canvas part. Has lasted almost 6-8 months with very little signs of wear. Feels very secure in any type of weather or condition. Great alternative or addition to having a pair of Stan Smiths.

Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.

Awesome value shoes
Size: 11.5, Color: Ivory/White/British Tan, Size: 11.5, Color: Ivory/White/British Tan
These white Cole Haan shoes are just what I hoped for, the color is a perfect off-white, somewhere between cream and pure white, which gives them a more refined look. The quality feels excellent, they’re very comfortable right out of the box, and the laces feel durable and well-made. They fit true to size with no issues. Based on this experience, I’ll definitely be buying more from this brand in the future especially at this price point.
