Product Overview
This boat outboard and stern drive water pump repair kit is designed as a replacement cooling system service kit for compatible Mercury outboard and stern drive applications.
It replaces Mercury part numbers 47-8M0100526, 47-43026Q06, 47-43026Q5, 47-43026T11, 47-43026T10, 47-43026T6, 47-43026T7, and 47-43026T8. It also cross-references Sierra 18-3214 and 18-3265.
The water pump impeller helps circulate cooling water through the marine engine to maintain proper operating temperature. A worn or damaged impeller may cause weak water flow, overheating, poor cooling performance, or possible engine damage.
Made with stainless steel and rubber components, this repair kit is built to handle seawater exposure and harsh marine operating conditions. Please compare the part number, impeller installation hole size, gasket shape, and product photos with your original water pump components before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This water pump repair kit may fit compatible Mercury outboard and stern drive applications using Mercury part numbers 47-8M0100526, 47-43026Q06, 47-43026Q5, 47-43026T11, 47-43026T10, 47-43026T6, 47-43026T7, or 47-43026T8. Fitment depends on the original part number, impeller size, gasket shape, and water pump housing design rather than model year alone.
Do I need to match the OEM part number?
Yes. For marine water pump repair kits, matching the part number is strongly recommended. Please confirm your original kit matches one of the listed Mercury part numbers or Sierra 18-3214 / 18-3265 before ordering.
What models or situations does this part not fit?
This kit may not fit marine engines with a different water pump housing, different impeller installation hole size, different gasket shape, or different repair kit part number. It is not recommended for Yamaha, Suzuki, Johnson, Evinrude, BRP, or other non-Mercury applications unless the part number and design match exactly.
What should I check before ordering?
Before ordering, check your marine engine brand, outboard or stern drive type, original part number, impeller installation hole inner diameter, gasket shape, housing design, and product photos. Make sure your original water pump components match this repair kit.
