Overview
- Slowly pour Mercury power trim fluid into the funnel until the fluid level reaches the “max” mark on the sight glass.
- If the fluid level is consistently low, there may be a leak in the system.
- Regular maintenance and fluid replacement will extend the life of your trim system and provide you with a reliable and efficient way to adjust your boat’s trim.
Maintaining the hydraulic fluid levels in your Mercury power trim system is crucial for its optimal performance and longevity. This guide will provide you with a step-by-step process on how to safely and effectively add hydraulic fluid to your Mercury power trim system.
Materials You’ll Need:
- Mercury power trim fluid
- Funnel
- Wrench or pliers
- Clean rags
Safety Precautions:
- Always wear gloves and safety glasses when handling hydraulic fluid.
- Do not smoke or use open flames near hydraulic fluid.
- Hydraulic fluid is flammable and should be stored away from heat sources.
Step-by-Step Instructions:
1. Check Fluid Level:
Locate the trim fluid reservoir, which is typically found on the side of the engine. Inspect the fluid level through the sight glass on the reservoir. The fluid level should be between the “min” and “max” marks.
2. Locate Fill Port:
Find the fill port on the reservoir. It is usually a small cap or plug located on top or side of the reservoir.
3. Remove Fill Cap:
Using a wrench or pliers, loosen and remove the fill cap. Be careful not to spill any fluid.
4. Insert Funnel:
Insert a funnel into the fill port. This will help prevent spills and make it easier to add fluid.
5. Add Fluid:
Slowly pour Mercury power trim fluid into the funnel until the fluid level reaches the “max” mark on the sight glass. Use a clean rag to wipe up any spills.
6. Reinstall Fill Cap:
Tighten the fill cap securely.
7. Cycle Trim System:
Start the engine and cycle the trim system up and down several times. This will circulate the new fluid throughout the system and remove any air bubbles.
8. Recheck Fluid Level:
After cycling the trim system, stop the engine and recheck the fluid level. If the fluid level has dropped below the “max” mark, add more fluid as needed.
Troubleshooting:
1. Overfilled Reservoir:
If you have overfilled the reservoir, drain the excess fluid using a syringe or turkey baster.
2. Low Fluid Level:
If the fluid level is consistently low, there may be a leak in the system. Inspect the hoses, fittings, and trim unit for any signs of fluid leakage.
3. Foaming or Discolored Fluid:
If the fluid is foaming or discolored, it may be contaminated and should be replaced.
Maintenance Tips:
- Check the fluid level regularly, especially before each outing.
- Change the fluid every 1-2 years or as recommended by the manufacturer.
- Use only Mercury power trim fluid or an equivalent approved by Mercury Marine.
- Keep the trim system clean and free of debris.
Wrapping Up:
By following these steps, you can ensure that your Mercury power trim system has the proper amount of hydraulic fluid for optimal performance. Regular maintenance and fluid replacement will extend the life of your trim system and provide you with a reliable and efficient way to adjust your boat’s trim.
