It generates the hydraulic pressure needed to extend and retract the trim tab actuators, and uses two integrated solenoid valves to direct fluid flow to each tab independently. The solenoid valves lock the tabs securely in position when not in use. A translucent fluid reservoir allows a quick visual fluid level check without removing the cover, and the included Lexan cover provides water resistance to the electrohydraulic unit. Uses automatic transmission fluid (ATF).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Mounting bracket sold separately — see the \u003ca href=\"\/products\/bennett-h1179-mounting-bracket-hydraulic-trim-tab-power-unit\"\u003eBennett H1179 HPU Mounting Bracket\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e12V electrohydraulic power unit for Bennett Classic hydraulic trim tab systems\u003c\/li\u003e\n\u003cli\u003eTwo integrated solenoid valves — independent port and starboard tab control\u003c\/li\u003e\n\u003cli\u003eSolenoid valves lock tabs securely in position when not actuating\u003c\/li\u003e\n\u003cli\u003eSufficient output to lower and hold even large trim planes\u003c\/li\u003e\n\u003cli\u003eTranslucent reservoir — fluid level visible at a glance\u003c\/li\u003e\n\u003cli\u003eLexan cover included for water resistance\u003c\/li\u003e\n\u003cli\u003eUses automatic transmission fluid (ATF)\u003c\/li\u003e\n\u003cli\u003eIncludes: pump, solenoid valves, reservoir, and Lexan cover\u003c\/li\u003e\n\u003cli\u003eMounting bracket not included — order H1179 separately\u003c\/li\u003e\n\u003cli\u003eBennett part number: V351HPU1 | Catalog SKU: 219-V351HPU1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBennett Classic Hydraulic Trim Tab Systems (all sizes)\u003c\/li\u003e\n\u003cli\u003eBennett M120 and M80 Sport Tab Systems\u003c\/li\u003e\n\u003cli\u003eAny Bennett hydraulic trim tab installation requiring a 12V HPU replacement\u003c\/li\u003e\n\u003cli\u003eBoats with 12V DC electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe HPU is the component to replace when the trim tabs stop responding entirely, the pump runs but produces no tab movement, or the unit leaks fluid internally.
