    Time for hydraulic steering!

    My boat just had its 30th birthday, so it is time to give her some serious TLC.

    First on my list is to pull the engine and OD so I can replace all the seals, then completely reorganize the engine space. New paint, bilge pumps and float switches, wiring harness, etc. I've always wanted all the gauges to work: only the oil and temp work, but that's another story for a different thread.

    I am also changing the cable steering to hydraulic. No more oil cooler, pump, and big hoses taking up valuable space. Then I want to move my alternator to where it is so I can finally have some belt adjustment.

    Anyone know which SeaStar system I need for my Cobra? I've been searching and reading and comparing and have finally glazed over. Not committed to any one system, just want one that works. I've had a SeaStar system before, and was happy with it. I just can't seem to figure out which one I need.

    I'm not sure why you'd want to change from the standard power steering set up that worked well for so long. I think the actuator that OMC used was better quality than the later Volvo SX actuators because you rarely hear of an OMC Cobra actuator going bad, but it is fairly common on the later units (SX). What other advantages would it give for the cost involved?

      Advantages:

      No more hydraulic pump.
      No more steering fluid cooler.
      More space created with the removal of the PA system.
      Assisted steering is not dependent on engine operation.
      No more pump drag on engine.
      Less heat producing components in engine bay.
      No future issues with cable actuated slave valve.
      No future issues with steering cable.
      No future issues with cable helm system.

      I would want what we call a "Balanced" system, whereby the hydraulic cylinder has equal hydraulic oil volume on each side of the piston.
      Same helm wheel revolutions for either Port or Stbd lock-to-lock turning.


      I think that you will enjoy having Hydraulic Steering over that of Power Assist.

        Ratios, mostly. We run out about an hour to fish, then troll on the kicker for 6 or 7 hours, then run back. We are constantly fighting the wheel. I'm with Bounty on this.

          OK well now I leaned something new! Sounds good
          PS
          how is your rebuilt Quadrajet working out?
          I redid mine in August and I found it was not the hard job some make it out to be. A little tricky to remove the air horn and then work the metering rods and choke linkage back in but only took me 2 hrs. I had tried a Holley and could not get it to run right so I pulled the old Q-Jet out of the garage and went to town on it with the carb cleaner and my air compressor.

            I failed to mention the ease of installing an Auto-Pilot with hydraulic steering.

              Adapters, this cylinder for this, and that one for that, ...this is very confusing. I just sent an email to SeaStar. Should hear back on Monday.

                  Start here. looks like the OMC cylinder for non power assist is BA150-7EM

                  I recommend you give them a call to verify you order all the correct parts.
                  here are the manuals.

                      Quadra-jet works great. Glad I kept it. Many thanks to Chuck at Olympic Marine in Port Angeles for looking after it for me.

                        Yeah, but I'd never use it in the Strait; too much debris, boat and ship traffic, and crab and shrimp pots. I also really enjoy being on the helm.

                            The trick is getting the emulsion tubes cleaned out, this is what often causes bad idling and low speed performance on Q-jets.
