Maintaining your Evinrude E-TEC outboard engine, particularly the trim and tilt systems, is crucial for ensuring optimal performance and longevity. This guide covers the essential steps for routine inspections and maintenance for 2012 models with 40, 50, 60, 75, and 90 horsepower engines.
Routine Inspections
Performing regular inspections on your outboard engine is the first step to preventing issues and ensuring smooth operation. Here are the key areas to focus on:
- External Fluid Leakage: Regularly inspect the engine for any signs of fluid leakage. If any leaks are found, identify and correct the cause immediately to prevent further damage.
- Battery Condition: Ensure the battery is in good working condition. A reliable battery is essential for the operation of the trim and tilt system and the overall performance of your outboard engine.
Reservoir Fluid Check
It's important to check the hydraulic fluid levels in the reservoir every three years or every 300 operating hours, whichever comes first. Here are the specifics for different engine capacities:
- 40-60 HP Models: The system capacity is approximately 15.2 fluid ounces (450 ml).
TRIM AND TILT SERVICE CHART 40 - 60 HP MODELS / A - Tripple-Guard Grease, W - Biodegradable TNT Fluid
- 75-90 HP Models: The system capacity is approximately 21 fluid ounces (620 ml).

IMPORTANT: Use only Evinrude/Johnson Biodegradable TNT Fluid for the hydraulic system. For detailed instructions on filling the system, refer to the "Trim and Tilt" section on page 41 of your owner's manual.
Manual Release Valve Inspection
The manual release valve should be checked with a wrench to ensure it is securely fastened.
IMPORTANT: Tighten the valve to a torque specification of 45 to 55 inch-pounds (5 to 6 N·m). Proper torque is essential to prevent leaks and ensure reliable operation of the trim and tilt system.
Stern Brackets Inspection
The stern brackets should be inspected for any signs of binding or wear. The starboard tilt tube nut must be checked and tightened if necessary.
IMPORTANT: Tighten the starboard tilt tube nut to a torque of 45 to 50 foot-pounds (61 to 68 N·m). This ensures the stability and proper functioning of the trim and tilt mechanism.
By adhering to these routine inspections and maintenance steps, you can help ensure your Evinrude E-TEC outboard engine operates efficiently and reliably. Regular maintenance not only extends the life of your engine but also enhances its performance, allowing for smooth and trouble-free boating experiences. Remember, consistent care and attention to detail are key to keeping your outboard in top condition.
