Accusteer Hydraulic Steering: Precision Control for Yachts and Commercial Vessels

When it comes to reliable, high-performance hydraulic steering on the water, Accusteer has built a well-earned reputation among mariners worldwide. Founded in 1993 by Bill Pulse and Paul Barber, Accu-Steer Inc. is a U.S.-based manufacturer that designs and builds a range of hydraulic power steering units for guiding and controlling motion on commercial vessels and pleasure craft. Today, Accusteer — now part of Kobelt — manufactures high-quality autopilot pump-sets, steering manifolds, power assist steering units, and hydraulic power units (HPUs).

What Sets Accusteer Apart in Hydraulic Steering

Accusteer's approach to hydraulic steering is defined by a philosophy of reliability-first engineering. Accu-Steer is dedicated to providing quality high-performance hydraulic control of steering systems for yachts and commercial vessels of all classes, with reliability as the primary design focus. That commitment is backed by a rigorous quality process: each unit is completely tested after assembly and identified by a serial number, with its test results on file at Accu-Steer, Inc.

The product line is the result of a continuing effort to offer a more reliable and serviceable product to the industry, designed to interface autopilot and electrical steering control to new or existing hydraulic steering systems — with installation simplified by the use of standard hydraulic fittings on all Accu-Steer products.

Accusteer Hydraulic Steering Product Lines

Accusteer's hydraulic steering lineup spans a wide range of vessel types and applications, from recreational boats to heavy commercial craft. Key product families include:

• Steering Manifolds (HM150 & HM450 Series): The HM150 is a single-speed manifold designed to interface hydraulic steering with autopilot and electronic control systems, available in two voltages with adjustable flow to suit both standard and custom requirements. The HM450 is a two-speed manifold designed to interface hydraulic steering to electric and autopilot control. An HM450S "Soft Shift" variant is also available for smoother engagement.
• Power Assist Units (PA-35): The PA-35 is a complete pump assembly consisting of a reversing gerotor gear pump and hydraulic lock valves, offering an accessible power assist solution for vessels looking to upgrade their existing hydraulic system.
• Hydraulic Power Units (HPU150, HPU200, HPU400): Accusteer offers autopilot steering pumps in a variety of configurations — from small single-speed reversing pumps to heavy-duty hydraulic power packs with dual speed and flow control — with pump volumes ranging from 0.4 to 4.0 gallons per minute, plus custom systems of 5.0 gallons and up, and a wide variety of motor drive voltages and solenoid voltages.
