Overview

The Raymarine T70330HK is an EV-150 Power Pilot package for small to medium powerboats with hydraulic steering, supplied with a 12 V Type 1 hydraulic pump and hose kit. It is made for single-engine outboard and single inboard steering systems with hydraulic cylinder capacities from 80 cc to 230 cc, or 4.9 cu. in. to 14.0 cu. in.

This below-decks autopilot system brings together the EV-1 sensor core, ACU-150 actuator control unit, p70Rs control head, pump, cabling, and hydraulic hose kit needed for a clean autopilot installation on compatible boats. The EV-1 uses a 9-axis sensor platform to read vessel movement, while the ACU-150 manages drive output to the hydraulic pump.

It is a practical fit for owners adding autopilot control to a hydraulically steered fishing boat, cruiser, or coastal powerboat where reduced helm workload and consistent course keeping matter during longer runs.

Key features

• Complete EV-150 hydraulic autopilot bundle with p70Rs control head, ACU-150 actuator control unit, EV-1 sensor core, Type 1 12 V hydraulic pump, EV1 cabling kit, and OC17SUK42 hose kit.
• For 12 V DC electrical systems only, with an operating voltage range of 10.8 V DC to 15.6 V DC.
• Matches hydraulic steering cylinders from 80 cc to 230 cc, or 4.9 cu. in. to 14.0 cu. in., covering many small to medium single-engine outboard and inboard powerboats.
• EV-1 sensor core uses 9-axis sensing to track vessel motion and help the pilot adapt to changing sea conditions.
• Hydro-Balance technology compensates for elasticity in hydraulic steering systems to reduce steering oscillation and drive-unit hunting.
• Evolution TrackIQ algorithms support tighter track keeping and faster track acquisition when following routes.
• ACU-150 drive output is rated for a maximum continuous 7 A at supply voltage.
• SeaTalkng and NMEA 2000 integration support with a Load Equivalency Number of 1.

Installation and setup

The EV-150 system is intended for below-decks installation with the hydraulic pump connected into the boat’s steering hydraulics and the control components integrated into the vessel’s electronics network. The included hose kit helps with the hydraulic side of the installation, while the EV1 cabling kit supports connection of the sensor, control head, and ACU-150.

Autopilot installation should be matched carefully to the boat’s steering cylinder volume, 12 V power supply, and available mounting locations. The ACU-150 should be mounted where it is protected and accessible for service, and the EV-1 sensor core should be positioned away from magnetic interference so it can read heading and vessel movement accurately.

Compatibility and fit

This package is for hydraulically steered boats within the 80 cc to 230 cc cylinder capacity range. It is not the right match for mechanical cable steering, 24 V-only installations, or hydraulic steering systems outside the stated cylinder volume range.

The system suits owners who want an integrated Raymarine autopilot for trolling runs, cruising legs, and offshore or nearshore passages where the boat spends meaningful time holding a heading or following a route.

Electrical and environmental details

The ACU-150 uses a nominal 12 V DC supply and has a standby power consumption of 300 mA at 12 V. Its listed dimensions are 180 mm wide, 140 mm high, and 52 mm deep, with a weight of 0.6 kg.

The ACU-150 is rated for operation from -20 °C to +55 °C and storage from -30 °C to +70 °C. The connector panel carries an IPx2 waterproof rating, while the drive electronics are rated IPx6, which is useful when planning protected mounting locations in a marine environment.
