Showcased at the Miami International Boat Show, which opened this morning, Mercury Racing’s new HD power steering-pump and High-Flow Helm deliver “a new level of high-performance steering for boats powered by multiple outboard motors,” including the Mercury Racing 450R outboard engine. According to press materials from the Fond du Lac, Wis., high-performance marine engine and accessories, the pump enables high-performance boat builders to assemble a complete, validated steering system for almost any application using components from Mercury Racing.

The HD power steering pump delivers 1,800 psi of pressure and a flow rate of 7.5 liters per minute, capacity designed to address the demands of high-speed, dual-engine catamarans executing extreme maneuvers. The new 80cc High Flow helm reduces lock-to-lock steering input on dual-engine catamarans for more-responsive handling, and reduces the ratio on boats powered by triple, quad, and more outboards that use more steering cylinders.
The HD pump also can be used with Mercury 40cc and 50cc helms, but the 80cc helm requires the HD pump to meet its flow requirement. The increased pressure and flow of the HD pump can also improve the power assist function on boats running multiple non-surfacing engines, including multi-engine pontoons.
“The HD steering pump fits in the same mounting space as the Generation B pump, and retrofit hose adapters will be available for use when replacing a Generation B pump with the new HD pump,” the release stated. “Mercury Racing steering components are engineered to work as a system, and feature quieter operation than competing systems.
