Understanding the functionality and maintenance of your 2012 Evinrude E-TEC 40, 50, 60, 75, and 90 horsepower outboard engines’ power trim and tilt system is essential for achieving optimal performance and ensuring the longevity of your equipment. This guide provides a detailed overview of the hydraulic components, proper adjustment techniques, and specific instructions for utilizing the trailering bracket and tilt support for these specific horsepower models.
System Description
The power trim and tilt hydraulic system is fully integrated within the outboard motor's stern brackets. Key components of this system include the electric motor, oil reservoir, pump manifold assembly, and cylinder body assembly. Proper adjustment, or trimming, of the outboard propeller thrust angle is vital for optimal boat performance. The initial 15 degrees of movement is known as the trim range, while any movement beyond this is referred to as tilting. Tilting is useful for shallow water navigation and for trailering or storing the outboard. It is important to ensure water is available to the gearcase water pickups during tilt operations.
Manual Adjustment
1. Manual release valve, 75-90 HP
To manually adjust the outboard within its full trim and tilt range, open the manual release valve by at least three turns. After adjustment, close and tighten the valve to a torque of 45 to 55 in. lbs. (5 to 6 N·m) before resuming normal operations.

Trailering Bracket and Tilt Support
40 – 60 HP Models
1. Tilt support bracket, 40-60 HP
These outboards feature a combined tilt support and trailering bracket. To engage the bracket, fully tilt the outboard up, engage the bracket, and then tilt the outboard down until the bracket is firmly in position.
75 – 90 HP Models
1. Trailering Bracket
For these models, the trailering bracket should be used to support the outboard in the tilted position while trailering, protecting the hydraulic system from damage. To engage the trailering bracket, fully tilt the outboard up, engage the bracket, and tilt the outboard down until it is securely in place. When moving or storing the outboard, use the tilt support. Do not use the tilt support for trailering purposes.

Summary
Proper understanding and maintenance of the power trim and tilt system are crucial for the effective and safe operation of outboard motors. This guide covers the system's components, adjustment procedures, and the correct usage of trailering brackets and tilt supports for various horsepower models. Following these guidelines ensures optimal performance and extends the lifespan of your outboard motor.
