High-Speed Hydraulic Steering for Performance Outboard Boats
The SeaStar Pro HH57704 is a front-mount hydraulic helm engineered for high-performance outboard applications — bass boats, flats boats, and other performance craft capable of speeds exceeding 60 MPH. Where standard hydraulic helms can feel vague or chattery at speed, the SeaStar Pro delivers precise, locked-in control that inspires confidence at the wheel.
The 2.0 cubic inch displacement provides more fluid volume per turn, reducing the number of lock-to-lock turns and giving the driver a more direct, connected feel. The long stud configuration accommodates thicker dash panels common in performance boat builds. The ORB (O-Ring Boss) port ensures a leak-free, secure hose connection.

Parts Desk Insights
Best Use Case: This is the helm to recommend for customers running high-performance bass boats, flats boats, or any performance outboard setup where speed exceeds 60 MPH. The 2.0 cu. in. displacement and long stud are specifically designed for this segment — customers who have experienced vague or chattery steering at speed will notice an immediate improvement.
Fitment Note: The long stud version is required for thicker dash panels — confirm dash thickness before ordering. For standard dash thickness, a short stud version may be available. Always verify cylinder compatibility with the helm displacement when building out a complete system.
Upsell Opportunity: Customers purchasing this helm are strong candidates for the full SeaStar Pro HK7500A3 Kit if they’re doing a full system build or replacement.
