    Help identifying part - picture attached-gctid405743

    Can someone help me identify this part?Hydraulic cylinder with water cooling through middle.1988 Bayliner Capri 190 BowriderChevy 305/5LIt has a crack near one end that is spewing water. Looks like previous owner repaired it with JB weld or something similar.Appreciate any insight.


    Cooler for power steering?
    Boatless at this time

      Ahhh... that makes sense. I appreciate the quick reply. Hopefully I can dig one up.

      Thanks again


        Yes, a power streering/transmission or other type of cooler. Follow the hydraulic lines to find what it cools. Water in/out on the ends; power/hydraulic fluid enters through the side ports. I also see a plug on one end and that is for a sacrificial zinc. For replacement, getting the exact same unit could be expensive. You can also install a generic one that could be a lot more inexpensive. I've seen them on ebay. Just make sure the in/out fittings are the same size and be sure to adequately mount the cooler..

        There ya go!

          Power steering cooler. I had my mechanic weld mine, much cheaper than replacing it and it has worked fine since.
