Uflex UP25FSVS SilverSteer™ Front Mount Hydraulic Steering Helm – 1.5 cu.in., High-Torque

Uflex UP25FSVS SilverSteer™ Front Mount Hydraulic Steering Helm – 1.5 cu.in., High-Torque

The Uflex UP25FSVS is the SilverSteer™ front-mount hydraulic steering helm — purpose-built for high-torque outboard applications where a standard hydraulic helm isn’t enough. Designed specifically for bass boats, flats boats, and high-horsepower boats with shallow deadrise, the UP25FSVS delivers the precise, responsive steering control that performance fishing and tournament boats demand.

At 1.5 cu.in. displacement with a ball bearing piston race and cast iron rotor, the UP25FSVS moves more fluid per stroke and handles higher sustained loads than standard helms — resulting in more direct, confident steering feel under power. The 1,500 PSI integral relief valve provides robust over-pressure protection for demanding applications.

Key Features

• 1.5 cu.in. Displacement — Higher fluid volume per stroke for more responsive steering in high-torque applications
• Ball Bearing Piston Race — Reduces internal friction for smoother, more consistent steering effort
• Cast Iron Rotor — Greater durability and longer service life under sustained high-load conditions
• Built-In Lock Valve — Provides positive rudder lock to hold steering position under load
• Integral Relief Valve — Over-pressure protection rated at 1,500 PSI (105 bar)
• 3/4" Tapered Stainless Steel Shaft — Accepts most standard marine steering wheels; stainless for corrosion resistance
• Adjustable 3/8" 45° Fittings Included — Flexible hose routing for clean installations
• Part Number: UP25FSVS | SKU: 216-UP25FSVS

Compatible Applications

• High-torque outboard applications — bass boats, flats boats, and tournament offshore fishing boats
• High-horsepower boats with shallow deadrise where standard helms feel vague or imprecise
• Pairs with the Uflex UC130SVS1 SilverSteer cylinder for a complete high-performance hydraulic steering system
• Compatible with Uflex Kit OBSVS hose kits and SeaStar-compatible hoses
• For standard-duty outboard hydraulic helm applications, see the Uflex UP25FM

Parts Desk Insights

Best Use Case: The UP25FSVS is the right helm when your current hydraulic steering feels vague, slow to respond, or lacks authority — particularly on high-horsepower bass boats, flats boats, and tournament rigs where precise, immediate steering response is critical. The combination of 1.5 cu.in. displacement, ball bearing piston race, and cast iron rotor makes this helm noticeably more direct and responsive than a standard hydraulic helm under load. It’s the helm component of the SilverSteer™ system and is designed to be paired with the UC130SVS1 SilverSteer cylinder — using a standard UC128 cylinder with this helm will underperform the system’s potential. For a complete SilverSteer system, see the Uflex SILVERSTEERXP1T complete system kit. For standard-duty applications, the UP25FM is the more cost-effective choice.
