Overview

The Garmin 010-00705-62 is a GHP SmartPump v2 hydraulic autopilot pump that ties into a boat's hydraulic steering system. It supports steering cylinder sizes from 4 to 24 cubic inches, with a configurable flow rate up to 2.4 L per minute so the steering response can be set for the boat.

In practice, it is the pump that moves the cylinder port and starboard under autopilot commands, while your helm and steering gear remain the foundation of the system. The unit is rated for operation from -15°C to 55°C (5°F to 131°F), which matters when the pump is mounted in a console, lazarette, or mechanical space that sees real temperature swings.

Corrosion resistance is handled with black-dyed aluminum parts and nickel-plated steel components, which helps in damp lockers and salt-air environments where unprotected hardware tends to show rust fast.

Key features

• Configurable flow rate up to 2.4 L per minute to tune steering response
• Compatible with steering cylinder sizes from 4 to 24 cubic inches
• Broad application range so you are not locked into a narrow pump size window
• Color-coded connectors to keep wiring straightforward during installation and service
• Corrosion-resistant construction with black-dyed aluminum parts and nickel-plated steel components
• Operating temperature range of -15°C to 55°C (5°F to 131°F)

Compatibility and fit

This pump is intended for hydraulically steered boats where the steering cylinder volume falls within the 4 to 24 cubic inch range. If your steering setup includes dual helms, power-assist modules, or other add-ons, plan the mounting location and hose routing so the pump can be integrated cleanly and still remain serviceable.

Installation and setup

Mount the unit where it stays accessible for hose connections, electrical plugs, and future service, and where it will not sit in bilge water. Keep hydraulic runs supported to reduce vibration wear, and bleed the steering system thoroughly after plumbing so the autopilot response stays consistent.

Electrical and system integration

Route the harness away from sharp edges and moving parts, add chafe protection where it passes through bulkheads, and seal connections against spray. The color-coded connectors help reduce mix-ups when you are working in tight spaces or returning to the install later for maintenance.

On-board use

This setup is a good match for boaters who want an autopilot pump that covers a wide range of common hydraulic cylinder sizes without swapping to a different pump model. It fits well on boats used for long coastal runs, offshore transits, and everyday cruising where reducing helm workload makes a difference.
