sevencow Water Pump Impeller Rebuild Kit for Johnson/Evinrude 9.5hp (1964–1973) & 10hp (1958–1963) — OEM 382296 Fit, Neoprene Impe

sevencow's 382296 Water Pump Impeller Rebuild Kit is a complete OEM-style replacement pack that restores cooling flow for Johnson/Evinrude 9.5hp (1964–1973) and 10hp (1958–1963) outboards.

If your vintage Johnson or Evinrude outboard is running hotter than it should or you hear cavitation and reduced cooling flow, the problem is often a worn impeller or degraded seals. This rebuild kit supplies the parts you need to replace the impeller, seals, housing components and fasteners so the pump can move seawater properly again. All items are designed to match OEM 382296 fitment for a direct replacement, making repairs straightforward for mechanically minded boat owners or marine technicians.

How will this kit improve my outboard’s cooling performance?

Replacing the impeller and associated seals restores the pump’s ability to draw and move cooling water through the engine. A fresh neoprene impeller compresses and flexes correctly inside the housing, reducing slip and restoring consistent flow.

• New neoprene impeller minimizes cavitation and leakage.
• Seals and bearing reduce shaft play and prevent leaks.
• Rebuilt housing and plate restore proper clearances.
• OEM 382296 compatibility ensures correct pumping geometry.

What parts are included and are they ready to install?

The kit arrives with every component needed for a standard water-pump rebuild so you won’t have to source extra pieces. It is intended as a direct replacement for the OEM set, making installation simpler when you follow the factory repair procedure.

• 1 impeller pump housing and 1 pump cup for the water path.
• 1 neoprene impeller, 2 plate pieces, and 2 seal bearings.
• 1 pin and 4 installation bolts included for secure assembly.
• Parts match OEM 382296 fitment for seamless swap-out.

How difficult is installation and what tools will I need?

Installation is moderate: doable for a competent DIYer with basic marine repair experience, or faster for a professional mechanic. The procedure typically requires removing the lower unit, disassembling the pump, swapping parts, and reassembling with proper torque and alignment.

• Common tools: socket set, screwdrivers, pliers and torque wrench.
• Recommended: water pump puller or careful hand removal to avoid damage.
• Follow manufacturer torque specs and shaft centering during reassembly.
• Allow time to inspect the housing and drive key for wear or damage.

Will these components fit my vintage Johnson or Evinrude outboard?

This rebuild kit is specified for Johnson/Evinrude 9.5hp models from 1964 to 1973 and 10hp models from 1958 to 1963. It matches the OEM 382296 part number and is intended to replace the original pump components directly.

• Confirmed compatibility: Johnson/Evinrude 9.5hp (1964–1973).
• Confirmed compatibility: Johnson/Evinrude 10hp (1958–1963).
• OEM reference: 382296—use this to cross-check older parts lists.
• If unsure, compare existing part shapes and dimensions to ensure fit.

Who is this for: The sevencow 382296 Water Pump Impeller Rebuild Kit is aimed at boat owners, marina mechanics and vintage outboard restorers who need an OEM-style replacement to restore cooling system reliability. It’s particularly useful for those who service Johnson or Evinrude lower units themselves and want a single boxed solution with the impeller, seals, plates, pump cup, pin and fasteners included. If you maintain classic outboards and prefer parts that match original specifications, this kit provides the components required to complete a standard water-pump overhaul efficiently.
