The Raymarine EV-100 Power Pilot T70154 is a complete autopilot package for smaller powerboats with hydraulic steering. It is aimed primarily at single-outboard installations with a compatible steering-cylinder volume. Before buying, the decisive check is the hydraulic system, not the boat length alone.

Raymarine EV-100 Power Pilot Complete System T70154
Best suited to: Owners of smaller hydraulic-steered powerboats whose cylinder volume and 12-volt system match Raymarine's requirements, with professional installation available when needed.
Main limitation: The included Type 0.5 pump is specified for 50 to 110 cc hydraulic steering cylinders. Boats outside that range, mechanical steering systems and more complex engine installations need a different pilot or a qualified system design.

Who it fits and who should choose something else
Good fit
- Compatible 50 to 110 cc hydraulic steering cylinder
- Smaller powerboat with a single outboard
- 12-volt electrical system with proper circuit protection
- Owner who understands that an autopilot does not replace watchkeeping
Choose another option when
- Mechanical or cable steering
- Cylinder volume outside Raymarine's listed range
- Twin or more complex steering system without a verified design
- Installation where steering or electrical work cannot be completed safely
What the important features mean
EV-1 sensor core
Raymarine's EV-1 is a nine-axis heading sensor that supplies vessel-motion data to the pilot. It reduces the amount of manual calibration, but correct mounting, power and steering setup still matter.
ACU-100 control unit
The ACU powers and controls the hydraulic drive. Raymarine lists a maximum continuous drive output of 7 A at supply voltage, so cable sizing, circuit protection and connection quality must follow the installation documentation.
Type 0.5 hydraulic pump
The included pump is the key compatibility limit. Confirm the steering cylinder's actual volume from the cylinder label or steering manufacturer documentation before ordering.
p70Rs control head
The T70154 package includes the rotary p70Rs control head. Raymarine also sells another package without the control head, so the SKU matters when comparing listings.
Setup, use and care
- Identify the steering cylinder and verify its volume from primary documentation.
- Plan EV-1, control-head, ACU and pump locations before drilling or wiring.
- Use the required marine cable, fusing and hydraulic fittings, and keep connections accessible for inspection.
- Commission and test the pilot at low speed in open water before relying on route or track functions.

Frequently asked questions
Does T70154 include the p70Rs control head?
Yes. Raymarine lists the p70Rs, ACU-100 and Type 0.5 hydraulic pump in the complete T70154 system.
What hydraulic cylinder size works with the included pump?
Raymarine specifies 50 to 110 cc, equal to 3.1 to 6.7 cubic inches, for the Type 0.5 pump.
Will it work with cable steering?
No. This package is for compatible hydraulic steering. A cable-steered boat needs a different drive approach.
Can an autopilot replace the person at the helm?
No. The operator remains responsible for lookout, safe speed and immediate control of the vessel. Autopilot is steering assistance, not unattended operation.
