  • Hydralic Steering

    I've got a Teleflex steering unit on my boat and I noticed it leaking fluid from under the steering wheel. Do I need to replace the entire unit under the steering wheel or do they make a rebuild kit?

    Double D,

    I found the seals for my steering cylinder here. They were the best price I could locate. If your unit is a SeaStar go to www.surplusunlimited.com. They have a listing for Hydraulic steering. I copied the SeaStar Helm Pump page. They also have listings for other units.

      is it leaking from the front of the helm? more often than not, it is a oring that is on the shaft that leaks. this is usually the first thing to go. the cause is usually from hanging on to the wheel in rough water etc.. really a poor desing imho, should be a bearing there instead with an oring.

        Ditto that. Its a $1.10 oring that sits under a flange thats held down with three screws. If you have a wheelpuller, phillips driver and an icepick, its a 5 min fix tops. Very common.

          My ex-marina says replacing the seals does nothing....they wanted to fix it for 360.00$$, it was the fastest 2.00$ repair i have ever done,about 5 minutes

          with the seal kit..and hasnt given me any trouble since!![:x)]

            You want to be sure that you use the proper Teleflex/Sea Star hydraulic fluid. Car-based steering fluid may kill your "O" rings faster. At least the car-based fluid is easier to see when it leaks out.

              Thanks for the help. Do I need to order a seal kit or can I get away with an o-ring from an auto parts store?

                dang!!!! $360 for fix it? They must of meant replace it right? for that kind of money, you can almost buy a new helm.

                  When you call teleflex they will send you an assortment of o-rings to use ..comes in a mini kit..I have even heard of them sending the little o-ring for free.

                    You need a special O-ring from sea-star/teleflex, it has a groove in the side, its not a straight o-ring. You dont need the whole seal kit. There are two types, and I couldnt figure out which exactly I needed, so I ordered both from the nearby boat/us. Its not, or at least wasnt here, a stocked item, had to special order. Damn shipping was more than the o-rings at $1.10 each.
