We put together a fully tested Simrad NAC-3 VRF autopilot system in great used condition, that is ALMOST complete. A drive and other accessories will complete the install.

We verified NMEA0183 comms with a Furuno VX2.

***NO PUMP OR DRIVE IS INCLUDED!!!***

This computer is currently setup as a VRF or “Virtual Rudder Feedback” system. Rather than using a trouble-prone rudder reference sensor to assess rudder position, the autopilot uses a set of algorithms based on vessel characteristics recorded during the commissioning procedure and fine tuned during use to accurately estimate rudder position at any given time.

If you need a feedback you can use a Simrad RF300, RF45X, RF25N, & RF70.

This is a nice system for someone who has an existing RPU160/300 pump (or similar) and is looking to upgrade.

The NAC-3 is recommended for outboard and sterndrive boats greater than 10 meters (35 feet) in length, and is suitable for use with high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.

PLEASE NOTE: Customer will have to purchase pump and other hydraulic accessories to complete the system. Or you can use your existing drive as long as it is compatible with the NAC-3. Please perform factory reset and calibration after the autopilot has been installed.

Thanks for looking.
