Where to buy
The Furuno PUMPHRP11-12 is an autopilot pump that runs on 12 VDC. Its stated pumping rate is 1.1 cubic inches per second, the flow figure to look at when judging how quickly it can move a ram. Furuno also gives a ram limit for it: ram sizes of up to 13 cubic inches in volume. If your steering ram is bigger than that, this pump is outside its stated range, so measure the ram volume first and match it to this rating.
Our take
The 1.1 cubic inches per second rate is the number that tells you how fast this 12 VDC pump moves fluid, and the 13 cubic inch ram limit tells you how big a cylinder Furuno rates it for. Measure your ram against that limit before you rely on it.
From our buying guide
Raymarine describes a typical autopilot as four parts: a heading sensor, a control unit, a drive and a control head. Bought alone, the parts don't steer, and Raymarine says the operator must stay at the helm at all times.
Check before you buy:
- The box list has the drive and control head you need, since packs can leave out a major part.
- It's rated for your boat the way the maker measures it. Raymarine sizes on fully laden displacement, often 20% above the designed figure.
- On hydraulic steering, the pump's range covers your steering cylinder's volume.
