Built-in lock valve, cast iron rotor, and adjustable nickel-plated brass fittings. It's the part that turns your wheel into smooth, fingertip control at the helm.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Uflex UP25T-SVS is the helm pump, the part that lives behind your dash and turns wheel motion into hydraulic pressure. Spin the wheel, the rotor pushes fluid down one hose to the steering cylinder, and the cylinder swings your outboard. Center the wheel and it holds. That's hydraulic steering in a nutshell, and this is the pump that drives it on a single-engine rig.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003etilt mount\u003c\/strong\u003e is the headline feature here. Instead of a fixed angle, the helm pivots so you can set the wheel where it actually feels right for how you sit or stand at the console. Anyone who's run a boat for hours with the wheel canted at the wrong angle knows how much that matters. You dial it in once at install and forget about it.\u003c\/p\u003e\n\u003cp\u003eDisplacement is \u003cstrong\u003e1.5 cubic inches per revolution\u003c\/strong\u003e. That number is what you match to your cylinder, and it's the spec that decides how the boat feels. A 1.5 pump is a common sizing for single outboards paired with an appropriately sized Uflex steering cylinder. Match the pump to the cylinder the way the fitment chart calls for and you get a steering ratio that's quick enough to be responsive without being twitchy at speed. Go look at your cylinder's displacement before you order anything, because that pairing is the whole game.\u003c\/p\u003e\n\u003cp\u003eInside, there's a \u003cstrong\u003ecast iron rotor\u003c\/strong\u003e doing the pumping and a shaft seal keeping the fluid where it belongs. The pump is rated to \u003cstrong\u003e1500 PSI\u003c\/strong\u003e working pressure, which is plenty of muscle for the loads a single outboard puts back through the system. One thing worth knowing from the field: cast iron holds up well, but if you ever see the shaft seal start to weep, deal with it. A weeping seal lets moisture at the rotor, and saltwater plus cast iron is a slow problem you'd rather not have. Replace the seal at the first sign of moisture and this pump will run for years.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ebuilt-in lock valve\u003c\/strong\u003e is the other piece that earns its keep. It holds the rudder steady and cuts the feedback that would otherwise come back up the column when a wave slaps the lower unit. Set your course, ease off the wheel, and the boat tracks. On a long offshore run that's the difference between a relaxed hand on the wheel and constantly correcting.\u003c\/p\u003e\n\u003cp\u003ePlumbing is straightforward. The pump comes with \u003cstrong\u003e90 degree adjustable nickel-plated brass fittings\u003c\/strong\u003e sized for \u003cstrong\u003e3\/8 inch hydraulic steering hose\u003c\/strong\u003e. The adjustable angle is a real help behind a tight dash, because you can rotate the fitting to line up with however your hose has to route. Give yourself extra hose length and gentle bends so nothing kinks when the helm tilts through its full range. A kinked line at full lock is a headache you can avoid at install.\u003c\/p\u003e\n\u003cp\u003eA word on the install itself. This is a job a handy boater can do, but respect the details. Cut your dash opening with enough clearance that the pump body doesn't bind when it tilts. Double-wrench those brass fittings and use the right thread sealant so they don't weep at the hose ends. And then bleed the system properly. Most stiff-steering complaints after a fresh install come down to air still trapped in the loop, not the pump. Fill, then cycle the wheel lock-to-lock a couple dozen times, tilt the helm to its extremes while you do it, and keep topping off the reservoir until the wheel turns smooth and firm with no sponginess.\u003c\/p\u003e\n\u003cp\u003eBottom line: the UP25T-SVS is a solid, serviceable tilt helm for a single-outboard hydraulic setup. Match it to the right cylinder, plumb it clean, bleed it fully, and you'll have steering that feels the way hydraulic is supposed to feel. Effortless.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e1.5 cubic inch per revolution displacement, sized for single-outboard hydraulic steering when matched to an appropriately sized cylinder\u003c\/li\u003e\n  \u003cli\u003eTilt mount lets you set the wheel angle for a comfortable helm position\u003c\/li\u003e\n  \u003cli\u003eBuilt-in lock valve holds course and cuts rudder feedback at the wheel\u003c\/li\u003e\n  \u003cli\u003eRated to 1500 PSI working pressure for single-engine steering loads\u003c\/li\u003e\n  \u003cli\u003eCast iron rotor for durability under load, with a serviceable shaft seal\u003c\/li\u003e\n  \u003cli\u003e90 degree adjustable nickel-plated brass fittings for easy hose routing behind the dash\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8 inch hydraulic steering hose\u003c\/li\u003e\n  \u003cli\u003eFront-mount hydraulic helm design for a clean dash install\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Uflex USA reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size boat or engine is this pump for?\u003c\/summary\u003e\n    \u003cp\u003eThe 1.5 cubic inch displacement is a common sizing for single-outboard hydraulic steering.
