When and How To Add Tilt and Trim Hydraulic Fluid

The ability to tilt and trim your engine can be found on most modern outboard engines if you own a boat. The understanding how your tilt and trim functions as well as how to perform some basic troubleshooting on your tilt and trim such as how to add tilt and trim hydraulic fluid will be a valuable resource to you at some point.

Tilting and trimming your engine enhances your boat's performance in a broad variety of situations, from smoothing out a rough ride in large waves to lowering draft in shallower waters.

If the tilt and trim motor is functioning normally, but the engine won't rise or lower, slips down while it is in the elevated position, or won't remain trimmed, the fault is probably with the hydraulic or the valve body assembly.

Add Tilt And Trim Hydraulic Fluid

The trim-and-tilt system is hydraulic, and because of this, it occasionally requires additional fluid. This is usually indicated when the system fails to trim entirely or “slips down” after being tilted up.

On top of the hydraulic reservoir is a screw with a hex head or a slot, which serves as the fill cap. The cylinder-shaped reservoir may be found in the space that is provided by the engine mounting bracket's uprights.

Because of its position usually being directly at the water's edge, the boat needs to be on land with its bow pointing down in order to level the reservoir, which is tilted at a negative angle of 13 to 15 degrees, the same as the transom. Make the necessary adjustments by winding down the tongue jack of the .

Here is how you will add fluid to your tilt and trim unit:

  1. Raise the and install the support bracket in the appropriate location.
  2. Remove the screw from the hole.
  3. Fill it up till it is almost spilling over. Wipe excess.
  4. To release trapped air from the engine, rock it back and forth.
  5. Add additional fluid (if it will take some).
  6. If necessary, repeat steps 4 and 5 again.
  7. Reattach the screw to its location.

In the event that the tilt and trim hydraulic fluid level is satisfactory, the issue is most likely caused by the hydraulic . Both the presence of fluid all around the piston assembly and a low fluid level are indicators that there may be a leak at the seals. At this stage, repairs normally include removing the pump and either rebuilding it or replacing it at a skilled repair facility. Alternatively, the pump might be replaced.

Overview

    • Most modern engines and boats come with the ability to tilt and trim the engine.
    • You will find it helpful to know how your tilt and trim works and how to do some basic troubleshooting on it.
    • By tilting and trimming your boat's engine, you can improve its performance in a wide range of situations, from making the ride smoother in chop to lowering the boat's draft in shallower water.
    • If the tilt and trim motor is working properly, but the engine won't rise or fall, slips down while it's up, or won't stay trimmed, the problem is probably with the hydraulic pump or the valve body assembly.
    • If the tilt and trim hydraulic fluid level is good, then the problem is probably with the hydraulic pump.
    • If there is fluid all around the piston assembly and the fluid level is low, this could mean that the seals are leaking.
