I have a Raymarine type 2 Electro-Hydraulic reversing pump-set.

The spec. says 24A Typical:

Can you support this ?

I also have a smaller Type 1 pump-set that is rated 19A as a backup; Possibly I could plumb this in in parallel.

Cheers,
JM.

I am in the progress of building a higher current controller which will be able to support this, but at this time, my current controller is big enough.

The autopilot computer would remain the same.

Not sure I understand?

What happens if the current controller encounters an over current condition ?

Thanks,
JM.
If over current is detected, the controller will not move in that direction any more. The max current possible in bursts is 20 amps for this controller, and 60 for the new controller.

This is from the drive stalling, typically.

It is different from over-temperature which will occur if the average current is too high and the components heat up. This controller can handle few amps average, the new controller should be able to average 20. In this case, the motor will stop until the controller cools sufficiently.

So, maybe the smaller controller will work, in some conditions with a hydraulic pump (provided it doesn't surge above 20 amps). For example, I average 1/4th watt (makes small adjustment every 15-20 seconds) for in light air and protected waters, vs 4 watts running down wind, with swells.
