Hynautic H-52 Hydraulic Helm Pump - SeaStar Replacement Kit

Hynautic H-52 Hydraulic Helm Pump - SeaStar Replacement Kit

The Hynautic H52 compact hydraulic boat steering helm was discontinued by SeaStar but you can purchase this direct replacement kit. This is a kit arranged by Seatech Marine Products with SeaStar parts, it is not a SeaStar part number.

What is included in this kit:

1. 1x HH5217-4 - 1.7 Cu.In Displacement - 3/4" Taper Shaft
2. 1x HA5418 - Back Mount Kit
3. 1x HA5432 - Non-vent plug
4. 1x HF6012 - -5 ORB Male x 1/4" Female NPT (1 kit, x3 fittings) 

How it Works:

• The Hynautic H-52 is a hydraulic steering helm that displaces 1.7 cubic inches of steering fluid.
• The Seastar helm pump HH5217-4 also displaces 1.7 cubic inches of fluid but you need other parts to make sure it fits the same hole in your dash and functions the same.
• The HA5418 back mount allows the SeaStar helm pump to take the same space as the H-50.
• The H-50 is usually used in a pressurized system, we need 1 of the HA5432 SeaStar non vented plugs to make sure we don't have oil leaking out of a vented cap of the SeaStar HH5217-4.
• Lastly, the HF6012 adapter fittings will allow you to use your current fittings that connect your your hydraulic hoses.

Other items you may need to purchase:

• SeaStar Steering Fluid
  
• SeaStar Steering Hose
