There are a few different ways to bleed trim and tilt mercruiser. The most common way is to use the manual override valve. This is usually located on the side of the power steering pump.
Other ways include using a vacuum bleeder or pressure bleeder. Whichever method you use, be sure to follow the instructions carefully so that you do not damage your engine.
- There are two ways to bleed the trim and tilt system on a Mercruiser
- The first is to use the bleeder screws located on the cylinders
- The second is to use a power bleeder
- If you are using the bleeder screws, start by opening them up about a quarter turn
- Then, have someone operate the trim or tilt switch while you watch for any air bubbles in the fluid
- Once you see fluid coming out without any bubbles, close the bleeder screw and check for leaks
- If you are using a power bleeder, connect it to the pressure side of the hydraulic line (the side that goes to the cylinder) and open up the valve
- Then, have someone operate the trim or tilt switch while you watch for any air bubbles in the fluid
- Once you see fluid coming out without any bubbles, close the valve and check for leaks

Mercruiser Trim Fluid Reservoir
As anyone who owns a boat knows, keeping it in good working order is important. One system that needs regular maintenance is the Mercruiser trim fluid reservoir. This holds the hydraulic fluid that helps move the boat’s outboard motors up and down.
Over time, this fluid can become dirty or low, which can lead to problems with the trim system.
To check your Mercruiser trim fluid reservoir, first make sure that the boat is turned off and in neutral gear. Then open the engine compartment and locate the reservoir.
It will be located near the stern of the boat, on either side of the engine. Once you’ve found it, remove the cap and check the level of fluid inside. If it’s low, add more until it reaches the fill line.
If it’s dirty, flush it out with clean water and refill with fresh mercruiser trim fluid.
It’s important to check your Mercruiser trim fluid reservoir regularly and keep it filled with fresh fluid. This will help ensure that your boat’s outboard motors are able to move up and down smoothly, making for a better ride overall!

How Do You Bleed Mercury Tilt And Trim?
If your outboard motor has a mercury tilt and trim system, you may need to bleed the lines if air has become trapped in them. This can happen if you run the engine out of water, or if you change the oil in the tilt and trim system without first draining all of the old oil out. When air gets into the lines, it can cause problems with how the system works.
To bleed the lines, you’ll need to have someone help you so that one person can operate the tilt and trim while the other bleeds the line.
1. Start by attaching a clear hose to the bleed screw on top of the power steering cylinder.
2. Have your helper slowly operate the tilt and trim until fluid starts coming out of the hose into a container.
3. Once fluid is coming out steadily, have your helper hold down on the button or lever to keep tilting or trimming while you loosen up onthe bleed screw so that air can escape along with some fluid. You may need to do this several times before all ofthe air is bled fromthe systemand only fluid is coming outof boththe hose and power steering cylinder filler hole..
How Do You Fill Mercury Trim And Tilt Fluid?
If your outboard motor is a Mercury Marine engine with power tilt and trim, it uses hydraulic fluid to move the components up and down. The amount of oil used in the system is small, so any leaks can quickly lead to big problems. Check the level of fluid in your reservoir regularly and top it off when necessary using only fluids that are specifically designed for use in Mercury power tilt and trim systems.
To check the level of fluid, locate the fill/drain plug on the side of the reservoir. Remove the plug and insert a finger into the opening. If your finger comes out clean, then there’s enough fluid; if it comes out covered in fluid, then you’ll need to add some.
When adding fluid, always use a product that’s been specifically designed for use in Mercury power tilts and trims. Other fluids may not provide adequate lubrication or protection against corrosion. To add fluid, remove the fill/drain plug again and slowly pour new fluid into the reservoir until it reaches the level of the opening.
Replace the plug securely when finished.
Why is My Tilt And Trim Not Working?
If your boat’s tilt and trim isn’t working, there could be a few different reasons why. First, you’ll want to check that the boat is properly plugged into the mains power – if it’s not, then the tilt and trim won’t work. Next, check the fuse box to see if any of the fuses have blown; if so, replace them with new ones.
Finally, if all of that is in working order, then it’s likely that the problem lies with the tilt and trim motor itself.
If your boat has an outboard motor, then the tilt and trim is controlled by a hydraulic system. The fluid levels in this system need to be checked regularly to ensure they’re at the correct level; if they’re not, then it could cause problems with the tilt and trim.
Similarly, if there are any leaks in the hydraulic system, this will also prevent the tilt and trim from working correctly.
In some cases, it might just be a case of replacing a worn-out part in the tilt and trim system. The most common parts that need replacing are the bearings or seals; however, depending on how old your boat is, it might be worth considering replacing the entire unit.
If you’re still having trouble figuring out why your tilt and trim isn’t working correctly, then it’s best to consult with a qualified marine mechanic who can diagnose and fix the problem for you.
What Fluid Goes in Mercruiser Trim Pump?
If you have a Mercruiser trim pump, the fluid you’ll need to use is mercuric chloride. This type of fluid is specifically designed for use in Mercruiser trim pumps, and will ensure that your pump operates properly.
Conclusion
If you have a Mercruiser trim and tilt system that isn’t working properly, you may need to bleed the system. This process is relatively simple, but it’s important to follow the steps carefully.
1. Start by locating the power steering reservoir.
This is usually located near the engine, so refer to your owner’s manual if you’re unsure.
2. Once you’ve found the reservoir, remove the cap and fill it with fresh power steering fluid until it reaches the “full” line on the side of the reservoir.
3. Next, locate the bleeder screws on each cylinder of the trim and tilt system.
There will be one bleeder screw on each cylinder- typically they are located near the top of each cylinder.
4. Using a wrench, loosen each bleeder screw about a quarter turn or until you see fluid start to seep out of each screw. It’s important not to loosen them too much, as this can cause fluid to spray out and make a mess!
5. With the bleeder screws still slightly loosened, start your engine and let it run for a few minutes while monitoring the level of fluid in your power steering reservoir. If necessary, add more fluid to keep it at the “full” line throughout this process.
6. While your engine is running, slowly tighten each bleeder screw until no more fluid seeps out- again being careful not to overtighten them!
Once all four screws are tightened back up, put your boat in gear (if possible) and check that your trim and tilt system is working properly- if not repeat these steps until it does!
