1. **Can I use my existing mechanical drive or hydraulic pump?**
Yes, you can use your mechanical drive or hydraulic pump as long as they are compatible with the system.any type of 12/24 volt reversing drives up to 30 amps are supported. You can test the drive by applying power directly to it and ensure the rudder moves in both directions by switching the wires (polarity). Some systems have separate (smaller) wires for a clutch output which may need power to engage the drive.

2. **What kind of mechanical drive do I need?**
typically drives a brushed dc motor that moves the rudder from -30 to +30 degrees in 6-8 seconds, however faster is usually better and slower is usually worse. You can find a variety of actuators online and suggestions on the the web.

3. **Can I mount the MCU32 anywhere in the boat?**
For best performance, you want to minimize acceleration and compass distortions. This means mounting closer to the center of the boat rather than the ends, however the exact location is not really critical. What is more important is to avoid magnetic interference such as: large pieces of ferromagnetic metal, magnets, floating compasses, speaker, wires carrying current (especially transient power like solar panel wires) and anywhere that objects are placed or moved to. You can easily experiment with this by looking at the heading reading on the MFD display and checking to see how it changes. The MCU32  can be mounted in any orientation but must be leveled once fixed to the boat.

4.  **Can I use an existing rudder feedback sensor?**
Yes, as long as the existing rudder feedback sensor is typically potentiometer based        1K-100K Ohm.
For NaviNet Autopilot the rudder feedback sensor is optional, however if you have a unit with a changing voltage with rudder angle, it will work with NaviNet Autopilot . 
 
5. **Can I use existing wind sensors?**
yes, NaviNet Autopilot can receive signalk and nmea0183 directly, for other types of N2K sensors it is possible by using KC2W NaviNet protocol converter.
 
6. **Can I use any 433MHz remote control I find online?**
You can use any 433MHz remote control, but ensure it meets the required specifications for compatibility.   Many (but not all) 433mhz remote controls will work. You can program them with the web APP.

7. **What is the typical power consumption?**
There is no definite answer because it depends on the boat, rudder, sea state, and conditions. Typical values for tiller-steered boats range from 1-3 watts (average) in light conditions to 5-6 watts in larger waves. For larger boats (50ft) with hydraulics, the power ranges from 10-15 watts up to 50-60 watts in stronger conditions.
