Troubleshooting & FAQ
Will this kit fit my Mercury or Mariner 150 HP outboard?
It fits select 150 HP 4-stroke EFI configurations, but 150 HP fitment is not universal. Verify the complete model designation, displacement, and serial number against the applicable parts catalog before purchasing.
Is OEM reference 8M0094529 the same as 47-43026Q06?
They should not be treated as interchangeable for this listing. Catalog material identifies 8M0094529 as a water pump complete service kit for applicable Mercury/Mariner 4-stroke applications, while 47-43026Q06 is associated with a separate Verado impeller repair-kit configuration.
Does this kit fit Mercury Verado engines?
Verado fitment is not confirmed for this listing. The Verado repair-kit references and serial-number conditions differ from the 8M0094529 complete service-kit application. Use the exact Verado model and serial number to identify the correct part.
How can I tell if my water pump requires service?
Possible warning signs include overheating, a weak or missing tell-tale stream, reduced cooling-water flow, or an abnormal temperature indication. Stop operation and inspect the cooling system promptly if any of these symptoms occur.
How often should a water pump be serviced?
Service intervals depend on the engine manufacturer's schedule, operating hours, and conditions such as saltwater, sand, or silt. Follow the maintenance schedule for your exact engine and inspect the pump whenever cooling performance is reduced.
Is this an OEM or aftermarket part?
This is an aftermarket replacement kit. It is associated with Mercury OEM reference 8M0094529 for application-identification purposes, but it is not a Mercury-branded OEM component.
What are your shipping speed and cost?
Typical transit is 5–15 days depending on destination and service level. Standard-shipping availability and any expedited options are shown at checkout where available.
What is the warranty and return policy?
Warranty and returns are handled according to the seller's current policy. Contact customer support with your order details before installing a part if you believe the supplied kit is incorrect or damaged.
