Replacement Actuator – Bennett A1101A Standard Trim Tabs

The Bennett A1101A actuator assembly is the hydraulic cylinder used with Bennett standard trim tabs, making it a focused replacement part rather than a full kit.

How We Picked Bennett Hydraulic Trim Tab Kits

We focused on compatibility, kit completeness, control options, and the types of boats each setup is best suited for. Because Bennett Hydraulic Trim Tab Kits range from full systems to replacement parts and conversion hardware, we also considered whether a product is a true all-in-one solution or a component for an existing system.

We gave extra weight to real-world usability: easier installation paths, clear indicator or control options, and sizes that match common hull layouts. That matters because the right tabs can improve hole shot, reduce porpoising, and help correct side-to-side list.

Quick Comparison

Start by separating full trim tab kits from parts. Complete systems are best if you’re upgrading from scratch, while actuators, controls, and conversion kits make more sense if you’re repairing or modernizing an existing setup. Tab size also matters: larger plates generally provide more lift and correction authority, while smaller plates can be a better fit for compact boats.

Key Buying Factors for Bennett Hydraulic Trim Tab Kits

Boat Size and Hull Shape

Choose tab dimensions that suit your transom width, hull length, and typical load. Oversized tabs can be unnecessary on smaller boats, while undersized tabs may struggle to level a heavy stern.

Controls and Feedback

Some boaters prefer basic hydraulic control, while others want indicator lights or auto-trim features for more precise adjustment. If you want easy visual confirmation, look for control systems with indication units or integrated feedback.

New Install Vs. Replacement

If you already have Bennett hardware, buying a matching actuator or conversion kit may be the most practical route. If you’re starting fresh, a complete hydraulic trim tab set is usually the simplest path.

Compatibility and Mounting

Check actuator length, mounting style, and system type before buying. Even within Bennett Hydraulic Trim Tab Kits, part compatibility can vary by classic system layout, control package, and tab size.

Who Should Buy Which Bennett Hydraulic Trim Tab Kits?

Choose a complete trim tab set if you want the easiest all-in-one upgrade. Pick a control or indicator unit if your current tabs work but the helm interface needs improvement. Select an actuator or piston replacement if you’re fixing a worn component. And consider a hydraulic-to-electric conversion kit if you want to modernize an existing hydraulic setup without changing the whole boat-side layout.

For most buyers, the best choice is the kit that matches both the boat’s size and the job you need it to do: full performance upgrade, targeted repair, or control-system refresh.
