Rated for outboards up to 150 horsepower, this front mount hydraulic cylinder replaces cable steering on a runabout, a center console or a pontoon and removes the feedback that tires an arm over a long day. The bore measures 32 mm with a 16 mm rod and a stroke of 197.3 mm, producing 409.7 kgf of output force at the tiller arm. Displacement runs 117 cc per side, which is the figure to match against a helm pump when specifying a complete system. Front mounting suits transoms where a side mount would interfere with a jack plate or a bracket. Hydraulic steering holds a heading with far less correction than a cable system, and it isolates prop torque from the wheel so a boat tracks straight at cruising speed. The cylinder installs with standard marine hardware onto the engine tiller. The cylinder carries the HC4645H reference for cross-checking a replacement.
Suits engines to 150 hp: The cylinder is sized for the torque a 150 horsepower outboard puts through the tiller, where a lighter unit would flex under load.
Output force of 409.7 kgf: A 32 mm bore and 16 mm rod develop enough force to turn the engine at speed without the effort a cable system transmits back to the wheel.
Displacement of 117 cc: The per-side volume is the figure to match against a helm pump so the number of turns lock to lock lands where a captain expects it.
Front mount configuration: Mounting ahead of the engine clears jack plates and brackets that block a side mount cylinder on many transoms.
Installation and care: The cylinder fits standard marine tiller hardware with a 197.3 mm stroke, surfaces wipe clean after saltwater exposure, and it is imported.
