UANOFCN Honda outboard water pump impeller service kit — fits BF35–BF50, neoprene impeller & stainless wear plate

UANOFcn's impeller service kit replaces the worn water pump components on Honda 35–50 HP 4-stroke outboard engines to restore proper cooling flow.

If your Honda BF35–BF50 outboard shows overheating, reduced cooling, or low water flow, this repair kit gives you the core parts needed to rebuild the water pump. The set matches OEM part numbers 06193-ZV5-020, 06193-ZV5-010, and 06193-ZV5-000 and includes a neoprene impeller, stainless wear plate and non-asbestos gaskets to bring your engine’s cooling system back to factory-style components.

How does this kit restore cooling performance?

Replacing the impeller and mating parts restores the pump’s ability to move coolant steadily through the engine. New neoprene vanes flex correctly against the wear plate and cover, producing the pressure and flow the engine requires under load.

• Neoprene impeller optimizes vane flexibility and lifespan.
• Stainless wear plate resists corrosion and maintains a flat sealing surface.
• Non-asbestos gaskets ensure a reliable seal without hardening.
• Direct fit for OEM part numbers listed for quick installation.

Which Honda engines are compatible with this rebuild kit?

This kit is designed for Honda 4-stroke outboards in the 35 to 50 HP range. It fits BF35A, BF40A, BF40D, BF45A, BF50A and BF50D models, provided you verify the exact motor model and serial number before ordering.

• Compatible models: BF35A, BF40A, BF40D, BF45A, BF50A, BF50D.
• Replaces OEM numbers: 06193-ZV5-020, 06193-ZV5-010, 06193-ZV5-000.
• Works with the factory water-cooling layout for these engines.
• Check motor model/s/n to avoid mismatches.

What materials and parts are included in the kit?

The kit supplies the wear-critical components used in most pump rebuilds so you don’t need to source parts separately. Materials are chosen to balance durability with safe operation in a marine environment.

• Neoprene impeller for resilient vane action in water.
• Stainless steel wear plate to resist pitting and keep clearances correct.
• Non-asbestos gaskets sized for the pump housing and cover.
• Matching fit to OEM dimensions for straightforward replacement.

How difficult is the installation and what should I prepare?

Installation is moderate for anyone familiar with outboard maintenance; basic hand tools and a service manual are recommended. Drain the cooling circuit, remove the lower unit, replace the old parts, and reassemble following torque specs.

• Recommended tools: socket set, screwdrivers, torque wrench, pump grease.
• Expect time: 1–2 hours for a practiced DIYer, longer if first-time.
• Follow Honda service manual steps and check seals before re-launching.
• Inspect housing and shafts for wear while the pump is disassembled.

Who is this for: UANOFcn’s 06193ZV5020 impeller service kit is aimed at boat owners, marine mechanics, and DIY enthusiasts who maintain Honda 35–50 HP 4-stroke outboards and need an accurate, OEM-referenced repair kit. If you perform routine seasonal maintenance, restore cooling after overheating incidents, or prepare older motors for reliable use, this kit provides the essential parts to rebuild the water pump quickly and affordably. Always confirm your engine model and serial number before purchase to ensure compatibility.
