Autopilot Pump, 12 VDC, 1.7 Cubic Inches Per Second (For Ram Sizes of 14 Cubic Inches to 25 Cubic Inches in Volume)
The PUMPHRP17-12 is a reversing pumpset designed to interface the NavPilot series autopilot with a hydraulic steering system. The pump assembly incorporates a reversible gerotor gear pump, a two-piece gear housed in an eccentric ring. This allows for incredibly quiet, reliable and precise operation.
A hydraulic steering system consists of a hydraulic actuator and one or more steering wheel pumps, or helm pumps. As the steering wheel (helm pump) is turned in the port direction, hydraulic oil is pumped into the port hydraulic steering line. This oil is directed into the port side of the steering cylinder. As the cylinder moves to port, oil from the starboard side of the cylinder returns to the helm pump through the starboard hydraulic lines.
One end of the cylinder is fixed and the other is connected to a tiller arm, which is connected to a rudder shaft. With this connection to the tiller arm the linear movement of the cylinder to port is changed to rotary movement, which turns the rudder and steers the vessel to port. Moving the steering wheel to starboard produces the same reaction with oil being pumped out of the starboard line and returning through the port line.
If more than one helm pump is used, a return/fill line must be installed to connect the cases of all helm pumps together.
The output flow rate of the pumpset determines the speed of the steering cylinder. The PUMPHRP17-12 outputs 1.6 cu. in. of oil per second and requires a 12VDC input.

Where Have You Been All My Boating Life?
What a great little piece of tech - I don't know how we got by without it in the past. No more guessing how full the holding tank is or having to clean icky tank senders. This little bluetooth RADAR sending unit mounts on top of the tank and connects wirelessly to our Victron Cerbo.
Setup is super easy, push the button on the unit so it can calibrate to the tank then enable bluetooth and set up your rank dimensions on your Cerbo. It's as easy as that.
We've had it installed and running for about two weeks now and couldn't be more pleased (We like it enough that I ordered a second one for our water tank.)
Lots of wiring - no leaks! Be sure to run ALL the wires through BEFORE completing the run!

"Currently" super happy.
Installed on Yanmar 4JH57 engines with Zeus Controllers - HOLY WOW power. Losing some power at top end but overall very satisfied. Will do a long term review later. Talk about power - hope to never need my generator again!
