Overview

The Raymarine T70154 is a complete EV-100 Power Pilot autopilot pack for smaller powerboats with hydraulic steering. It combines the EV-1 sensor core, ACU-100 actuator control unit, p70Rs control head, cabling, and a 0.5 liter hydraulic pump in one system for single-engine outboard boats.

The included Type 0.5 hydraulic pump is for 12 V DC systems and is matched to outboard hydraulic steering cylinder capacities from 50 cc to 110 cc, or 3.1 in3 to 6.7 in3. This makes fit confirmation especially important before purchase, since the pump size must match the boat’s steering cylinder capacity.

On the water, the system is meant to reduce constant helm corrections during cruising, fishing runs, or long transits. The EV-1 sensor core uses 9-axis sensing to read vessel motion, while Hydro-Balance steering control helps limit drive-unit hunting in hydraulic steering systems.

Key features

• Complete EV-100 Power Pilot pack for smaller powerboats with hydraulic steering.
• Includes a Type 0.5 hydraulic pump for 12 V DC systems.
• Pump compatibility covers outboard hydraulic steering cylinders from 50 cc to 110 cc, or 3.1 in3 to 6.7 in3.
• EV-1 sensor core uses 9-axis sensing to track vessel motion and changing sea conditions.
• ACU-100 actuator control unit manages the hydraulic pump and autopilot drive output.
• p70Rs control head gives helm-based autopilot control with buttons and a rotary control layout suited to powerboat installations.
• Hydro-Balance steering control helps compensate for elasticity in hydraulic steering systems and limits unnecessary steering movement.
• SeaTalkng cabling is included for integration with the Raymarine Evolution autopilot network.

Installation and fit

This autopilot pack is intended for boats with traditional hydraulic steering, where the pump is connected into the hydraulic steering lines and controlled by the ACU. The key fit check is the steering cylinder capacity: the included pump is sized for 50 cc to 110 cc cylinders and should not be treated as a universal hydraulic pump for every outboard installation.

The ACU-100 is a 12 V DC unit with an operating voltage range of 10.8 V DC to 15.6 V DC. Mount the electronics in a location that suits the boat’s wiring layout and exposure limits, keeping service access in mind for future checks and cable routing.

System integration

The EV-100 Power Pilot works as part of Raymarine’s Evolution autopilot system. The p70Rs control head handles direct autopilot control at the helm, while compatible Raymarine Axiom chartplotters can also be used for autopilot control when the system is set up on the network.

This pack is a practical match for owners of smaller hydraulic-steered outboard boats who want steady course holding without piecing together the major autopilot components separately. It is especially relevant for coastal cruising, fishing, and longer runs where reducing hand steering can make the helm workload much lighter.
