56851-003 – Reservoir – Honda

The 56851-003 reservoir is an OEM tank made for Honda outboard engines and trim/tilt systems. This tank stores hydraulic or trim fluid, ensuring proper fluid supply and consistent system function. It fits engines that list part 56851-003 (or equivalent codes such as 56851-V15-003) in their parts diagrams.

Installing a new 56851-003 reservoir ensures correct fluid containment and prevents leaks. That helps maintain performance and reliability when using your outboard in salt or fresh water. The reservoir mounts directly to the engine’s standard brackets and seals securely with factory-spec fittings.

This part is brand new — unused and ready for installation. It’s ideal for restorations, maintenance, or as a spare for future repairs. Simple installation makes it a good choice for DIYers and marine mechanics alike.
