Even the products from the most reliable brands like Mercury often run into this issue with the outboard motor. It can be quite annoying when you can’t properly adjust the angle of your unit to get optimal performance out of your unit.

If you’re also in a situation where outboard motor trim will not stay up, then the following list of troubleshooting methods will help you maneuver this problem.

Outboard Motor Trim Will Not Stay Up

1. Tighten Release Valve

Among other factors, issues with the manual release valve are most common for users struggling with outboard motor trim not staying up. So, if you’re having no issues with elevating the engine but it comes down after a while, then there is a good chance that the manual release valve is not tight. That is why your motor will come down after staying in up position for a few moments.

In most situations, you won’t have to do anything more than tighten up the release valve. So, access the manual release valve and make sure it is tightened properly in the close position. Now, you can try to use the trim to see if it will stay up. Hopefully, the issue will be fixed at this stage.

2. Replace O Rings

If you’re sure that the release valve is tightened properly, there is a good chance that you’re dealing with an O ring problem. These rings can get loose or damaged over time if you put your unit through rough use. So, even if the valve is tightened properly, replacing the O rings is a good option for you.

You won’t have to spend an extended amount of budget on this unit, and the issue will be fixed in no time. So, just go to your nearest hardware store and grab yourself an O ring replacement for your release valve. Install it in the unit and then test the trim feature again. The issue will most likely be fixed at this stage.

3. Check Hydraulic Fluid

Another factor that you have to keep in mind while dealing with this issue is the hydraulic fluid. Most anglers that are running into this issue mention that the hydraulic fluid levels on their unit were not sufficient.  So, if you’ve not checked the hydraulic fluid levels on your unit for a long time, now might be a good idea to do so.

Most often than not, you will find that the hydraulic fluids are low. You can easily get around this issue by adding more fluid to the reservoir. It won’t take any more than a few minutes, and your trim will stay up without further issues. However, if you’re still stuck in the same problem, make sure to seek help from local experts.
