Uflex UP33FSVS SilverSteer™ Front Mount Hydraulic Steering Helm – 2.0 cu.in., High-Torque

Uflex UP33FSVS SilverSteer™ Front Mount Hydraulic Steering Helm – 2.0 cu.in., High-Torque

The Uflex UP33FSVS is the larger of the two SilverSteer™ front-mount hydraulic steering helms — delivering 2.0 cu.in. of displacement per stroke, compared to 1.5 cu.in. on the UP25FSVS. Designed specifically for high-torque outboard applications including bass boats, flats boats, and high-horsepower boats with shallow deadrise, the UP33FSVS provides the most responsive, direct steering feel of any standard Uflex hydraulic helm.

With a ball bearing piston race, cast iron rotor, and 1,500 PSI integral relief valve, the UP33FSVS is built to handle sustained high-load steering conditions that would stress a standard hydraulic helm.

Key Features

• 2.0 cu.in. Displacement — The highest fluid output in the standard Uflex SilverSteer™ helm lineup; more responsive steering feel under high-torque loads
• 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: UP33FSVS | SKU: 216-UP33FSVS

Compatible Applications

• High-torque outboard applications — bass boats, flats boats, and tournament offshore fishing boats
• High-horsepower boats with shallow deadrise where maximum steering responsiveness is required
• Applications where the UP25FSVS (1.5 cu.in.) provides insufficient output for the cylinder and system size
• Compatible with Uflex Kit OBSVS hose kits and SeaStar-compatible hoses
• Pairs with the Uflex UC130SVS1 SilverSteer™ cylinder for a complete high-performance hydraulic steering system
• For standard-output front-mount helm applications, see the Uflex UP25FM or UP28FM

Parts Desk Insights

Best Use Case: The UP33FSVS is the top of the standard Uflex hydraulic helm lineup in terms of displacement — choose it when the UP25FSVS (1.5 cu.in.) still doesn’t deliver the steering responsiveness you need, typically on the largest high-horsepower bass boats, offshore tournament rigs, and multi-engine performance applications where maximum fluid output per stroke translates directly to faster, more precise steering response. The 2.0 cu.in. displacement means fewer turns lock-to-lock and more immediate response under load compared to the 1.5 cu.in. UP25FSVS. Like the UP25FSVS, it’s 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. If the UP33FSVS is more helm than your application needs, the UP25FSVS is the more cost-effective SilverSteer™ option.
