Power trim is a feature on modern boats that allows the operator to adjust the angle of the motor’s propellers to optimize performance in different water conditions. It is an essential aspect of boating, as it can significantly impact a vessel’s speed, fuel efficiency, and handling. However, if you notice that the power trim slowly goes down, it could be a sign of a more severe problem that requires prompt attention.
In this article, we will explore the possible causes of this issue and provide some helpful tips on how to diagnose and repair it.
Why is the Power Trim Slowly Goes Down: Quick Overview
Like I added a quick view table for Blue Wave Boat problem, and I’ve added a quick table for the power trim slowly going down the issue. Let’s check it out.
Reasons for Power trim slowly goes down | Repairing the Problem |
Low hydraulic fluid levels | Regularly checking and maintaining hydraulic fluid levels |
Worn or damaged hydraulic seals | Inspecting and replacing worn or damaged seals |
Faulty hydraulic pump | Regularly servicing the hydraulic system |
Malfunctioning trim motor | Properly storing and maintaining the boat and its components |
Clogged hydraulic lines or filters | Regularly servicing the hydraulic system |
Possible Causes of the Problem

Several factors could contribute to the power trim slowly going down, including:
Reason 1: Low hydraulic fluid levels
The hydraulic system that powers the trim relies on hydraulic fluid to function correctly. If the fluid level is low, it can cause the trim to move slowly or not move at all.
Worn or damaged hydraulic seals: Seals are critical components of hydraulic systems that prevent fluid leaks and maintain pressure. If they are worn or damaged, they can cause the hydraulic system to malfunction.
Reason 2: Faulty hydraulic pump
The hydraulic pump generates the pressure needed to move the trim. If the pump is not working correctly, it can cause the trim to move slowly or not move at all.
Reason 3: Malfunctioning trim motor
The trim motor powers the hydraulic pump and controls the direction of the trim. If the motor is not working correctly, it can cause the trim to move slowly or not move at all.
Reason 4: Clogged hydraulic lines or filters
Hydraulic lines and filters can become clogged over time, restricting fluid flow and causing the trim to move slowly or not move at all.
When talking about this reason let me share another piece of info. Due to clogged fuel filters the Evinrude intruder 150hp may face difficulties.
Diagnosing the Issue Power Trim Slowly Goes Down

To diagnose the issue, you should perform the following steps:
- Check the hydraulic fluid level: Make sure that the fluid level is sufficient and that there are no leaks in the system.
- Inspect the hydraulic system for leaks: Look for signs of fluid leakages, such as puddles or wet spots near the hydraulic components.
- Test the hydraulic pump and trim motor: Use a multimeter to check the voltage and amperage output of the pump and motor to determine if they are working correctly.
- Examine the hydraulic lines and filters: Check for any signs of blockages or damage in the hydraulic lines and filters that could cause the system to malfunction.
Fixing Power Trim Slowly Goes Down Problem
Once you have identified the cause of the problem, you can take the following steps to repair it:
Fix 1: Add hydraulic fluid if necessary
If the fluid level is low, add more fluid to the system to restore the proper level.
Fix 2: Replace worn or damaged seals
If the seals are worn or damaged, they will need to be replaced to prevent further fluid leaks.
Fix 3:Repair or replace the hydraulic pump or trim motor
If the pump or motor is faulty, you may need to repair or replace it to restore proper function to the hydraulic system.
Fix 4: Clean or replace clogged hydraulic lines or filters
If the lines or filters are clogged, clean or replace them to restore proper fluid flow.
Preventive Maintenance
To prevent similar issues from occurring in the future, you should:
- Regularly check and maintain hydraulic fluid levels: Check the fluid level regularly and add more fluid as necessary.
- Inspect and replace worn or damaged seals: Check the seals regularly and replace them as necessary to prevent fluid leaks.
- Regularly service the hydraulic system: Have the hydraulic system serviced regularly by a professional to keep it in optimal condition.
- Properly store and maintain the boat and its components: Store the boat and its components in a dry, clean, and secure location when not in use to prevent damage or wear and tear.
That’s everything on the power trim slowly goes down the issue. This issue generally appears on Yahama, Mercury, and Evinrude boats. No matter what’s your boat, you should be able to fix it following this guide.
