Uflex UP25FM Front Mount Hydraulic Steering Helm – SeaStar Compatible, 3/4" Tapered Shaft
The Uflex UP25FM is a front-mount hydraulic steering helm engineered as a direct drop-in replacement for SeaStar® helms — same mounting footprint, same shaft, same hose compatibility. With a compact design, built-in lock valve for positive rudder lock, and an integral relief valve for over-pressure protection, the UP25FM delivers reliable, precise hydraulic steering for outboard and sterndrive applications without requiring system-wide replacement.
The UP25FM is compatible with Teleflex/SeaStar cylinders, hoses, and oil, and works with Uflex Kit OB and Kit OBSVS hose kits — making it a straightforward upgrade or replacement for existing SeaStar hydraulic steering systems.

Parts Desk Insights
Best Use Case: The UP25FM is the right helm when you need to replace a failed SeaStar front-mount helm without replacing your entire hydraulic steering system. The direct drop-in compatibility means you keep your existing cylinders, hoses, and oil — only the helm changes. The front-of-dash fill is a practical advantage over older helm designs that require helm removal for fluid service. The built-in lock valve is standard on this helm and provides positive rudder lock, which is important for boats that sit at anchor or in current where you want the steering to hold position without drifting. If you’re building a complete hydraulic steering system from scratch rather than replacing a helm, consider one of the Uflex PROTECH complete system kits which bundle the helm, cylinder, and oil together. For tilt helm configurations, see the PROTECH21T.
