The Rubber Seal Water Pump Impeller Repair Kit from Buckshot Racing #77 is a direct replacement for the Mercury Marine / Racing Impeller Repair Kit 43026Q06 for the 300X, 300XS Optimax, 4-Stroke Verado, and many outher outboard models.
 
Our impeller replacment kit eliminates the need for the traditional gasket and thin metal plate setup and replaces it with a single metal plate that incorporates an integrated rubber seal.
 
The revised design improves sealing, reduces installation errors, and extends service intervals by removing the need for periodic gasket replacements.
 
Traditional impeller repair kits rely on a separate gasket that can degrade over time due to exposure to heat, water, and pressure. By integrating the rubber seal into the metal plate, this design ensures a more uniform seal, improving water pump efficiency and reducing the risk of leaks.
 
The upgrade is compatible with a wide range of Mercury Marine and Mercury Racing outboards, from smaller EFI engines to high-performance Verado and Pro XS models.
 
Mercury Outboard Compatibility
 
This impeller repair kit fits a variety of Mercury Marine and Mercury Racing outboards, including 2-stroke and 4-stroke models across multiple horsepower ranges.
 
For smaller outboards, this kit is compatible with 40 HP EFI (4-cylinder), 40 HP EFI Jet (4-cylinder), 50 HP EFI (4-cylinder), 55 HP (3-cylinder), 60 HP (3-cylinder), 60 HP EFI (4-cylinder), 75 HP EFI, 80 HP EFI, 80 HP Jet (3-cylinder, 1.5L), 90 HP EFI, and 90 HP (3-cylinder, 1.5L) models. These engines are commonly used in recreational boating, fishing, and light commercial applications.
 
In the mid-range category, this kit fits 100 HP EFI, 105 HP EFI Jet, 115 HP EFI, 115 HP Pro XS (3-cylinder, 1.5L), 125 HP EFI (3-cylinder, 1.5L), 135 HP EFI, and 135 HP EFI Verado (4-cylinder). These models require consistent water pump efficiency to maintain peak performance and durability.
 
For higher horsepower engines, the repair kit is compatible with 150 HP EFI, 150 HP EFI Verado (4-cylinder), 175 HP EFI Verado (4-cylinder), 200 HP EFI (3.0L), 200 HP Verado (4-cylinder & 6-cylinder), 225 HP EFI (3.0L), and 225 HP Verado (6-cylinder). These engines are often used for larger boats, offshore applications, and high-performance marine activities.
 
For high-output applications, this kit supports 250 HP EFI (3.0L), 250 HP Pro Verado (6-cylinder), 250 HP Verado (6-cylinder), 275 HP Verado (6-cylinder), 300 HP EFI Pro Max (3.0L), 300 HP Pro Verado (6-cylinder), 300 HP Verado (6-cylinder), and the Mercury Racing 300 XS 3.2-Liter Stroker. These engines operate under extreme conditions and require consistent water flow and durable cooling system components.
 
The kit is also compatible with the 350 HP SCI Verado (6-cylinder), making it suitable for Mercury’s most powerful outboard engines.
