Tutor Auto Water Pump Repair Kit for Johnson Evinrude V4 V6 V8 85-300HP - Neoprene Impeller & Housing

Keep your outboard’s cooling system performing reliably with a full repair kit that includes a neoprene impeller, housing, seals, gasket, fasteners and all parts needed to rebuild the seawater pump. This kit is a direct-fit replacement for many Johnson and Evinrude models, designed to match OEM dimensions so you can complete the job quickly without sourcing individual components.

How does this kit restore engine cooling?

The kit supplies the key wear parts that move and seal coolant through the pump: a flexible impeller, precision housing and new gaskets and seals. Replacing those elements removes flow loss and leakage caused by worn blades or warped housings, returning water throughput to factory levels.

• Neoprene impeller for flexible, high-wear resistance.
• Replacement housing machined to fit OEM intake and outlet ports.
• New seal, gasket and mounting fasteners to prevent leaks.
• Pre-assembled options available to speed installation.

Which motors and part numbers are compatible?

This repair kit is compatible with a wide range of Johnson and Evinrude outboards—V4, V6 and V8—covering horsepower ratings from 85 to 300 HP. It replaces common OEM numbers so you can match it by part reference rather than guessing fitment.

• Replaces Johnson/Evinrude OEM 5001594, 390768, 395060 and related numbers.
• Compatible with Sierra part 18-3392 and other equivalent references.
• Works on many Johnson/Evinrude 85–300 HP V4, V6, V8 models—check your engine's part listing.
• Hand-inspected parts to help ensure proper fit and function.

What materials and quality should I expect?

Tutor Auto builds this kit from durable materials chosen for marine environments: a neoprene impeller for flex and longevity plus precision metal housing for accurate alignment. Components meet or exceed OEM specifications for direct-fit performance while offering cost savings versus buying OEM-branded parts.

• High-grade neoprene impeller resists wear and abrasion.
• Metal housing machined for correct clearances and longevity.
• Complete gasket and seal set to restore leak-free operation.
• Quality control inspections before shipping.

How long will installing the kit take and what tools are required?

Installation time depends on experience and engine accessibility; many technicians or DIYers complete a pump rebuild in one to two hours. Basic hand tools and a torque wrench are typically sufficient—no specialized equipment is required for most models.

• Typical install time: 1–2 hours for a practiced installer.
• Needed tools: sockets, screwdrivers, pliers, gasket scraper, torque wrench.
• Follow engine service manual for torque specs and alignment procedures.
• Pre-assembled option reduces time by eliminating part-by-part assembly.

Who is this kit for? This Tutor Auto repair kit is intended for boat owners, marine mechanics and service shops maintaining Johnson or Evinrude outboards that rely on seawater cooling. It’s ideal when the impeller shows wear, the housing is corroded or you need a complete rebuild kit to restore pump performance without the premium price of OEM-branded parts. If you value direct-fit parts, clear compatibility with multiple part numbers, and a 12-month warranty, this kit offers a practical replacement solution.
