Overview

The Raymarine M81167 is a 12V DC solenoid valve for Raymarine Raypilot autopilot systems. It is used in marine steering installations where the autopilot needs electric valve control as part of the vessel’s hydraulic steering setup.

This is not a general-purpose freshwater, fuel, or sanitation plumbing valve. It is a Raymarine autopilot component for boats using compatible Raypilot steering hardware, so the key buying check is system fit rather than pipe size alone. For a refit, repair, or replacement, match the existing autopilot system, voltage, and valve arrangement before installation.

Key features

• 12V DC solenoid valve for Raymarine Raypilot autopilot applications.
• Used with hydraulic steering control where the autopilot actuates steering through a valve-controlled setup.
• Suitable for marine autopilot service on vessels that already use compatible Raymarine Raypilot hardware.
• Useful as a replacement component when the existing 12V Raypilot solenoid valve is worn, damaged, or being updated during steering system service.
• Helps keep autopilot steering response tied to the correct electrical control voltage and steering system layout.

Compatibility and fit

Confirm that the boat’s autopilot system is a Raymarine Raypilot setup that calls for a 12V solenoid valve. Autopilot steering parts must be matched to the steering architecture on board, including the hydraulic circuit, the control electronics, and the DC supply voltage.

Before ordering, compare the installed valve, wiring, and steering documentation for the vessel. This part should be treated as a system-specific autopilot component, not as an interchangeable plumbing valve for unrelated onboard fluid systems.

Installation and setup

Installation should be handled with the steering system secured and depressurized as required by the vessel’s hydraulic setup. The electrical connection should be made on a protected 12V DC circuit that matches the Raypilot control arrangement.

After installation, the steering system should be checked for correct valve operation, leaks, smooth helm response, and proper autopilot control at the dock before the boat is tested underway.

Use cases on board

This valve is a practical match for owners and service technicians maintaining a Raymarine Raypilot autopilot on a powerboat or sailboat with hydraulic steering. It is most relevant during autopilot repairs, steering system troubleshooting, or replacement of a failed 12V solenoid valve in an existing Raypilot installation.
