need help identifying a water

need help identifying a water cooled hydraulic pump on a 1967 Jeffboat Sunliner Houseboat. The housing has 1/4 copper tubing coiled inside with fresh water being pumped through it from the water pump. The hydraulics go to a servo or piston of some kind on the back of the motor... not sure if its power assist steering or shifting. The copper coil burst from freezing over the winter and we're replacing it.
