Uflex UC133IOB Sterndrive Hydraulic Steering Cylinder – Universal Transom Mount
The Uflex UC133IOB is a universal hydraulic steering cylinder designed for sterndrive applications — attaching directly to the transom shield at the same location where a mechanical steering cable would otherwise connect. Built from anodized aluminum and stainless steel, it provides a clean, durable hydraulic steering solution for most sterndrive-powered boats without requiring custom fabrication or bracket modifications.
The UC133IOB is the larger of the two Uflex sterndrive cylinder options, offering greater displacement than the UC132OBS for applications that demand more fluid volume and steering authority.
Key Features
- Universal Sterndrive Design — Fits most sterndrive applications; attaches to the transom shield at the standard steering cable connection point
- Anodized Aluminum and Stainless Steel Construction — Corrosion-resistant materials for long-term marine durability
- Transom Shield Mount — Replaces the mechanical steering cable connection for a clean hydraulic conversion
- Larger Displacement — Greater fluid volume per stroke than the UC132OBS for higher-demand sterndrive applications
- Compatible with Uflex UP25, UP28FM, and UP28T Hydraulic Helms — Designed for use with these specific Uflex helm models
- Part Number: UC133IOB | SKU: 216-UC133IOB
Compatible Applications
- Most sterndrive-powered boats requiring a hydraulic steering cylinder at the transom shield
- Higher-demand sterndrive applications where the UC132OBS cylinder is insufficient
- Hydraulic steering conversions from mechanical cable systems on sterndrive applications
- Recommended for use with Uflex UP25, UP28FM, or UP28T hydraulic helms
- Verify fitment against your specific sterndrive model and transom shield configuration before ordering
- For lighter-duty sterndrive applications, see the Uflex UC132OBS Sterndrive Cylinder
- For outboard front-mount hydraulic cylinder applications, see the Uflex UC128TS1 Protech cylinder or UC130SVS1 SilverSteer cylinder
Parts Desk Insights
Best Use Case: The UC133IOB is the right sterndrive cylinder when your application demands more than the UC132OBS can provide — typically on larger sterndrive engines or boats where the smaller cylinder doesn’t deliver enough steering authority or feels vague under load. Like the UC132OBS, it mounts at the transom shield where the mechanical steering cable would otherwise attach, making it a clean conversion option for most sterndrive boats without additional fabrication. It’s matched to Uflex UP25, UP28FM, and UP28T helms; pair this cylinder with one of those helms and the appropriate hose kit when building a complete sterndrive hydraulic system. If you’re unsure whether your application needs the UC132OBS or UC133IOB, the UC133IOB is the safer choice for larger engines and higher-horsepower sterndrives. Always verify fitment against your specific sterndrive model before ordering.
