Frequently Asked Questions
What is the difference between Type 0.5 and other Raymarine hydraulic pumps?
The Type 0.5 pump is designed for smaller hydraulic steering systems with cylinder capacities between 50cc-150cc. It provides 750 PSI maximum pressure and is specifically optimized for Volvo D4/D6 sterndrive applications and boats requiring moderate steering assistance.
Can this pump replace an EV100 Powerpilot system?
Yes, the E12139 Type 0.5 pump is specifically designed as a replacement component for EV100 Powerpilot systems, providing enhanced reliability and performance when paired with the ACU-100 control unit.
What size hydraulic steering system is compatible with this pump?
This pump is compatible with hydraulic steering cylinders ranging from 50cc to 150cc (3.1 to 9 cubic inches). It's essential to match the pump capacity to your specific hydraulic steering system for optimal performance.
What additional components are needed for installation?
You'll need an ACU-100 Actuator Control Unit, an Evolution autopilot display unit, appropriate hydraulic fittings, 12V power supply with proper circuit protection, and professional installation is recommended for system integration and calibration.
Is this pump suitable for both inboard and sterndrive applications?
While the Type 0.5 pump can work with various hydraulic steering systems, it's specifically optimized for Volvo D4/D6 sterndrive applications. For other engine configurations, consult with a qualified marine electronics installer to ensure proper compatibility.
