LED Indicators, Auto Retract and All Up/All Down Preset – Suits Most Trailer Boats 15′-20′ – 12 Volt
Suits Most Trailerboats 15′-20′ – 12 Volt
Overview:
Bolt Electric Trims tabs are best suited for boats that are kept out of the water when not in use. A good rule of thumb is if your boat requires antifouling paint you should install a hydraulic system. They are ideally suited to small craft such as flats boats, bass boats and bay boats. Open skiffs and other small boats are perfect candidates since there is no hydraulic pump to locate in the boat. Electric motors in the actuators cannot be precisely synchronised so they are limited to one actuator per Trim Tab.
An attractive and user-friendly, stand-alone helm control without the need for an external control unit. The functionality and “brains” of the control unit are engineered directly into a single, space-saving, and simple-to-install keypad. Reduce bow rise, plane faster, and correct listing.

Why Have Trim Tabs? As your boat slows from maximum speed, it begins to settle at the stern or “squat,” creating an inefficient, untrimmed condition. At this attitude you use more fuel to drive the boat. As the boat pushes forward, it creates a “hill of water.” In this bow-high position, visibility is limited and the hull bottom is pounded. Also because of significant hull drag and extreme prop angle, fuel economy is poor. Uneven weight distribution makes your boat harder to handle, even harder to get up on plane, and it causes your boat to list to one side. Your passengers complain when you tell them to move from one side to the other.

Note: The Bolt Trim Tab kits are available in sizes 12 x 9 or 9 x 12 or 12 x 12 inch.
There is also a choice of three different Control Switches:- the Bolt Euro Standard Control switch (this has no trim tab position indicator and no auto retract), the Bolt OBI9000E Control Switch with LED Indicators and Auto Tab Retract, or the Bolt Indicator Control Switch with Auto Tab Retract. The Auto Trim Tab Retract feature automatically retracts the trim tabs when the ignition is turned off. Ideal for trailer boats, rack and stack boats being fork-lifted at the marina or when beaching in shallow water.Other Trim Tab Kits:

How to Choose Between Bolt Trim Tabs or Hydraulic Trim Tabs?
You’ve decided to install Trim Tabs on your boat and have begun researching which ones will be the best choice.
After you have made the choice of size (our website gives size recommendations for each tab kit) , you will need to choose between the Hydraulic Trim Tab Kits or the Bolt Electric Trim Tab Kits.
To help you decide let’s take a look at the features and benefits of both systems.
- Bennett Hydraulic Trim Tab Systems:- have set the standard for durability for decades. Hydraulic systems are robust and will last for many years. With the electric pump safely mounted inside the boat in a dry location they are the best choice for boats kept in the water.
Since the nature of hydraulics permits precise synchronisation of multiple actuators per Trim Tab, they are well suited for high speed and rough water applications.
The construction of the system also allows many components to be replaced if damaged, meaning the system can easily be repaired in the field at low cost by the boat owner.
It is true that hydraulic systems take more time to install than electric ones, but it is not difficult and easily within the skills of the average boat owner.
- Electric Trims Tabs Systems:– are best suited for boats that are kept out of the water when not in use. A good rule of thumb is if your boat requires antifouling paint you should install a hydraulic system.
They are ideally suited to small craft such as flats boats, bass boats and bay boats. Open skiffs and other small boats are perfect candidates since there is no hydraulic pump to locate in the boat.
Electric motors in the actuators cannot be precisely synchronised so they are limited to one actuator per Trim Tab.
Installation is a breeze you can start in the morning and be out running the boat before lunch. Their exclusive upper hinge design means no exposed wires and eliminates the need to reassemble them during installation.
Now that you have decided on the right system for your boat it’s time to consider which control and indicators you wish to choose.
