diad,
Can you please provide more detailed information regarding:
1. What is the vessel type and length..?
2. What is the Model of the Drive Unit that is currently installed..?
3. What is the type and size of the cylinder displacement of hydraulic rams..?
4. When the Drive Error is given, what is the speed of the vessel at that time..?

Hi Deep Blue Sea,
The boat is a 31' Center Console
The hydraulic pump is the Furuno FRP17-12
Not sure of the displacement of the cylinders. It may be about 12cu in. They are Sea Star HC5345-3 rams.
The error occurs at all speeds. Including 30kts down to trolling speeds.
Thank you,

Here is a couple of things that you can try:
You might perform another full factory reset and re-calibration of the NAVPILOT300. Somehow the Rudder diagnostics passed, but there might be a setting that is causing these "Rudder Drive Errors".
Check to see what the gauge and the length of power wires is supplying voltage to the pilot. If it’s not heavy enough gauge or if they are corroded, this could be causing power loss, and drawing way too much amperage. :noway
The Sea Star rates the HC5345-3 steering cylinders at 8.34 cubic inch. If you have these cylinders, then the HRP11-12 pump would be more appropriate. The HRP17-12 is rated at 14-25 cubic inches and could be too big of a pump set for this particular steering system.
Hope this helps.

If the cylinder is 8 cu and there are two of them wouldn't that be 16cu for the larger pump? We have tried the factory reset and that did not work.
Any opinions on if a power pack or regulator would solve the issue? These are expensive components and I would hate to just buy things to try. If these would solve the problem it would be nice if Furuno let this be known that there are added expenses.

Earlier you said 12cu and now it is 16cu. When the values change the answers will also. It would be best to have a dealer get involved to ensure you are getting a suitable pump for your steering system.
Johnny,
I said that it may be 12" but I went on to say the Seastar part number. It was then determined that the ram was 8" and that there were 2 of them, therefore 16" total. That was my question, do you size the pump by one ram or if there are more than 1 do you add them together?
There is a dealer involved including a professional installer. This is the first install that this dealer/installer have had for the navpilot300. I'm just trying to help and also to understand.
My apologies if the questions weren't asked in the proper format.

Pumps are sized by the Cubic Inches of volume they are pushing. If you have two or more cylinders you must add them together to get the total volume you are pushing to rate the pump.
