Installation Notes
- Disconnect the battery and follow the outboard manufacturer's safety procedures.

- Remove the water-pump housing and inspect the housing, wear plate, keyway, seals, and related components.
- Remove the old impeller and check the drive-key arrangement before fitting the replacement.
- Install the replacement impeller with the blades oriented in the direction of shaft rotation.
- Because this kit does not include the outer plate, reuse only a serviceable plate that matches the correct pump design; replace damaged or excessively worn parts as required.
- Reassemble the water-pump housing and lower unit using the correct torque specifications from the engine service manual.
- Run the engine in water or with an appropriate flushing device and verify a steady cooling-water tell-tale stream before normal operation.
Troubleshooting & FAQ
How do I know if this impeller kit fits my Johnson or Evinrude engine?
Confirm that your outboard is a listed 2-stroke 35 HP model with a thermostat from 1958–1959, or a listed 40 HP model from 1960–1966 or 1967–1970 with the correct electric-shift or manual-shift configuration. Also compare the existing OEM reference and the impeller dimensions. Horsepower alone is not sufficient to confirm fitment.
Does the kit include the outer plate?
No. The company product specification identifies this configuration as a water pump impeller kit without the outer plate. Inspect the existing plate and replace it separately if it is scored, warped, or excessively worn.
What are the signs of a failing water-pump impeller?
Common signs include a weak or missing tell-tale stream, overheating warnings, rising operating temperature, or visible cracks, stiffness, deformation, or missing blades on the old impeller.
How often should I replace the impeller?
Replacement intervals depend on operating hours, storage conditions, water quality, and the manufacturer's maintenance schedule. Inspect the impeller regularly and replace it when it shows wear, hardening, cracking, or loss of blade shape.
Is this an OEM component?
This is an aftermarket replacement part. The listed OEM numbers are provided for identification and cross-reference purposes only. Johnson, Evinrude, OMC, Sierra, Mallory, GLM, and CEF are trademarks of their respective owners.
How fast is shipping?
Standard delivery is typically estimated at 5–15 days, depending on destination and carrier service. Available shipping options and delivery estimates are shown at checkout.
What is the warranty and return policy?
This product is covered by the seller's applicable warranty against manufacturing defects under normal use. Returns are subject to the current return policy and condition requirements. Contact support with your order details for assistance.
