hello, i have a 422 and the PO had already started the install of a raymarine auto pilot, because we use cable steering it needed a bypass valve, part no.M81167, to allow the movement of fluid while in manual mode. i need to know the routing of the hoses from the pump to the ram thru the bypass valve. it is not in the pump install guide or anywhere on the raymarine website. thanks.

Howard:
See page 26/55 of attached manual:
Speaking of hydraulic autopilots, I have one to install as well. Rather than
going the by-pass valve route to tie into the mechanical steering, I was
thinking of converting the whole system over to hydraulic steering. Since
the ram is already in place, the additional cost isn’t that great.Has anyone converted to hydraulic steering on their boat.
Thanks,
Paul

Paul,
I'm familiar with hydraulic steering on a few friends' boats, none a p424. All of the sailboat owners hate it. The only advantage is the ability to install multiple steering stations (all of these friends have either pilot house sailboats or trawlers). The sailboat owners consider it a maintenance headache with no helm feedback when sailing. Of course they won't give up that inside steering station so they just live with the issues.Not sure what advantage it will give you on the P424.

Paul,
Forgot to mention:IMO the advantage you have with an autopilot that it is independent of the steering system (except for the rudder) is it provides a backup in case either the wheel system fails. I assume you could configure a system with independent hydraulics for the autopilot and the wheel, but then you lose the savings of a single Ram. I would not want a system that if either the wheel steering or the autopilot failed it would take out the other.
It sounds to me that with the system you are considering if the hydraulic lines spring a leak you are immediately down to the emergency tiller (something I never want to happen).
Then again I know very little about hydraulic steering systems.

All the autopilots I’ve seen that were fitted to cable steered boats were either mechanical or were hydralic ram designed to operate independently of the cable system. Good ones have an independent tiller, the others bolt directly to the quadrant. If you have a pump without a solinoid valve to disengage the autopilot, then chances are it was intended to be part of a hydralic steering system. We chartered a big Morgan years ago with a hydralic steering, and it was terrible, John is right.
For anyone contemplating a Nexus A/P, Defender has several hydralic ram drives in their clearance stuff for $500, a steal.
