Bennett Hydraulic Trim Tab Actuator Assembly | 13.75" Closed Length (A1101A)

The Bennett A1101A is the standard replacement hydraulic actuator (ram) for most Bennett Classic trim tab systems. Known for its legendary reliability and simple, leak-proof design, this actuator has been the industry standard for decades. It is a "through-transom" design, meaning the hydraulic fluid line is concealed behind the mounting hinge, protected from the elements and potential damage.

Durable Engineering for the Marine Environment

Constructed from high-strength, fiberglass-reinforced nylon, the A1101A is entirely impervious to corrosion and electrolysis. Its "closed-loop" hydraulic system ensures that the piston is moved by fluid pressure provided by the Hydraulic Power Unit (HPU), offering incredible holding power even in rough seas.

Key Features:

• Through-Transom Hydraulics: The hydraulic hose connects to the back of the upper hinge, allowing the tubing to pass directly through the transom. This eliminates exposed hoses on the exterior of the boat.

• Fiberglass-Reinforced Nylon: Extremely tough construction that will not rust, pit, or corrode, regardless of saltwater exposure.

• Standard 13.75" Length: This is the universal size used in the vast majority of Bennett "Classic" kits found on boats from 15 to 40 feet.

• Simple Maintenance: Features an internal spring-return mechanism and a heavy-duty piston seal designed to last for years without service.

• Easy Retrofit: Designed to be a direct replacement for any standard Bennett hydraulic actuator with no new drilling required in most cases.

Technical Specifications:

• Model Number: A1101A

• Closed Length: 13.75" (Center of pin to top of mounting hinge)

• Type: Hydraulic

• Material: Reinforced Nylon

• Compatibility: All Bennett Hydraulic Power Units (HPU)

• Mounting: Standard 4-hole upper hinge pattern

Installation & Maintenance Tip:

When replacing an older actuator, ensure that the hydraulic tubing is cut cleanly with a sharp blade (not side cutters) to ensure a leak-free "push-to-connect" fit into the new actuator. It is also recommended to apply a small amount of marine sealant around the screw holes and the hydraulic nipple during installation to maintain a watertight transom.

Pro Tip:

If your actuator is leaking fluid or failing to retract, the A1101A is the complete assembly needed for a total fix. While seal kits are available, replacing the entire assembly is often the most cost-effective way to ensure another decade of trouble-free operation.
