Seastar 2.4 Helm HH5272-3

Seastar 2.4 Helm HH5272-3 the worlds most popular hydraulic steering systems.  The Seastar helms are the smoothest and most efficient hydraulic steering available. Manufactured by Seastar Solutions formerly known as Teleflex Marine.

Specifically designed the helm pump is an axial piston pump for manual steering. It has a built-in lock valve to prevent the steering load from feeding back to the driver. And the lock valve will not allow the rudder or drive unit to move until you move it with the steering wheel. Whilst the lock valve section of the helm also includes a relief valve. This relief valve provides over-pressure protection for mechanical components and hydraulic hoses and fittings.

Note on Steering Response versus Steering Effort.
Steering wheel effort is directly proportional to the number of wheel turns lock-to-lock. Lock-to-lock is dependent on two things.
Volume of cylinder.  more volume = more wheel turns with less effort
Displacement of the helm pump. higher displacement = less wheel turns/faster response with more effort.

As a result 3 turns from lock-to-lock (single cylinder) when using 2.4 helms. The reason why dive and fishing operators launching thru the surf, opt for this helm for the quick response.
