Trim tabs help maintain optimal performance on the water. In the event that weight is distributed unevenly on the boat or water conditions are contributing to a rough ride, a reliable set of trim tabs gives the operator the lift they need to ensure a smooth, comfortable excursion.  

How to Fill a Trim Tab Pump? 

There are two power supply options with trim tabs. Some are electrically powered, which entails using a control panel to adjust trim tab actuators. These actuators move the metal planes up and down to change how the boat moves in the water.  

Hydraulic trim tabs work differently in that they use hydraulic pressure to move the planes into and out of the water. This pressure is supplied by a hydraulic power unit, which is filled with fluid. A few key steps are required to refill the power unit: 

• Check fluid levels in the power unit to determine whether a refill is needed 
• Locate the left corner of the reservoir to find the Lexan cover and filler plug 
• Remove the plug and supply fresh hydraulic fluid 
• Most power units have a line indicating full, so keep supplying fluid until you reach that line 
• Replace the plug when the reservoir is full 

Make sure the trim tab planes are in the up position when refilling the hydraulic power unit. In the event your hydraulic power unit lacks the full indication line, continue adding fluid until there’s only one inch of space between the fluid and the top of the reservoir.  

What Fluid to Use With Trim Tab Pumps? 

One of the great things about Bennett trim tab pumps is that they can be filled with a variety of automatic transmission fluids. In fact, you can mix two different fluids within the pump without concerns about improper function.  

However, some boating professionals recommend using a fluid that’s colored red, as opposed to a clear version. That’s because it’s easier to detect a leak with red transmission fluid.  

How to Replace a Trim Tab Pump 

When it comes to boating maintenance, trim tab pump replacement is likely to be on your list of chores. The continuous performance of pumps can cause them to wear down over time, but replacement components will help the equipment work like new again.  

To begin, disconnect the old pump from the wiring and put the new model in its place. Take your hydraulic line and connect it to the pump. Use hose clamps to keep the lines in place, otherwise there may be interruptions when sending hydraulic fluid from the pump to the actuators.  

Next, you’ll need to connect the wiring harness to the new pump. It’s also necessary to route the wires from the control panel to the new pump. In some cases, you may want to replace the switch when you’re replacing the trim tab pump.  

In the event you’re experiencing multiple issues with function, investing in trim tab kits from Power Boat Supply might be the best course of action.  

How Do Trim Tab Pumps Work? 

Pumps are just one of many components used to operate this helpful boating accessory, along with trim tab indicator gauges and control panels, actuators, and planes.  

Pumps are integral in the function of trim tabs, as they provide hydraulic fluid that allows actuators to move up and down, which then positions the planes into and out of the water. Hydraulic fluid remains within the pump until the trim tab controls are engaged by the operator. At this point, the pump sends fluid through the hose, which fills the cylinders.
