DESCRIPTION The power trim unit consists of manifold that contains all valving, oil reservoir, oil pump, electric motor and hydraulic trim cylindersAttached to the manifold is the combination hydraulic tilt cylinder and shock absorberThe entire assembly is attached to and contained completely between the stern brackets while the tilt cylinder is the only component actually connected to the moving parts of the motorTrimming is accomplished by the trim cylinders pushing on the swivel bracket at the thrust padsBy operating the electric switch in the "up" direction, the electric motor drives the hydraulic pump forcing oil into the trim cylinders and the tilt cylinderBecause of mechanical and hydraulic advantage, the trim cylinders move first, trimming the motor through 15 At the end of the trim cycle, the trim cylinders are fully extended and the tilt cylinder moves the motor through the final 50 of motionThe outboard can be operated while tilted past the initial 15 for shallow water driveAbove approximately 1500 rpm, an automatic overload lowers the motor to the fully trimmed out pOSitionAttempts to tilt the motor over 1500 rpm will have no effectA trim gauge is provided with the motorA sending unit is attached to the port stern bracketIt is accessible with the motor fully tiltedSee Figure 9-2
