It is part of the Uflex UP-BB series, engineered for the high horsepower, high torque outboards found on fast bass boats with very shallow deadrise hulls. Uflex describes this line as the racecar of helms, built to feel tight and responsive under load.\u003c\/p\u003e\u003cp\u003eThe UP28FM has a 1.7 cubic inch displacement and features a 1500 psi (105 bar) pressure relief valve, letting it deliver precise steering even at high torque loads. Internally, a ball bearing piston race keeps the steering feel smooth, while a built-in lock valve holds the rudder in position when the helm is not being turned. An integrated relief valve protects the system from over-pressure damage at 105 bar (1500 psi). The pump uses a 3\/4 inch tapered stainless steel shaft for long-term durability and 90 degree adjustable nickel-plated brass fittings that make hose routing easier in tight helm installations.\u003c\/p\u003e\u003cp\u003eFor correct high-torque performance, the UP28FM must be paired with the Uflex UC128-SVS hydraulic cylinder and the Uflex Kit OB-SVS hose kit, both purpose-built for this same high-torque application. This helm pump is intended for bass boat steering systems and similar fast, shallow-deadrise vessels running high horsepower motors.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Uflex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e UP28FM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Helm Pump, Front Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 1.7 cubic inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure:\u003c\/strong\u003e 1500 psi (105 bar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft:\u003c\/strong\u003e 3\/4 inch tapered stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFittings:\u003c\/strong\u003e 90 degree adjustable, nickel-plated brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Race:\u003c\/strong\u003e Ball bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Valve:\u003c\/strong\u003e Built-in, for positive rudder lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Valve:\u003c\/strong\u003e Integrated, over-pressure protection to 105 bar (1500 psi)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Cylinder:\u003c\/strong\u003e Uflex UC128-SVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Hose Kit:\u003c\/strong\u003e Uflex Kit OB-SVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 11.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 702755021612\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for bass boats and similar fast, shallow-deadrise vessels equipped with high horsepower, high torque outboard motors that require a quick-response front mount helm.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eThe UP28FM is a Uflex helm pump in its own product line;
