Get the most from your boat, no matter what the load, speed or sea conditions, with Bennett trim tabs.
A trim tab system gives you fingertip control of your boats ride. Using the helm control, you can adjust the trim tabs individually or together to create the perfect cruising attitude and smooth a rough ride. Trim tabs can help your boat get on plane faster, increase speed and improve fuel economy. Bennett hydraulic trim tabs are known for power, precision and durability and are available for boats large and small. To make installation a little easier, Bennett assembles trim tab kits to fit a variety of boats. Each kit includes 304 stainless steel trim plane assemblies, hydraulic power unit, actuators, a control switch, hydraulic tubing, wiring and hardware; installation requires normal household tools plus marine sealant, epoxy and automatic transmission fluid (ATF). Hydraulic hoses are run internally through the mounting flange of the actuators to eliminate exposed tubing. Use the guide below to determine the right Bennett kit for your boat and take control of your boat’s ride by installing trim tabs.

Trim Tab Guide:
As a starting point use the general rule that for every foot of boat length the trim tab should have an inch of width or cord. Meaning if your boat is 25 feet long, the trim tab should have a cord of 25 inches or more. Generally a trim tab with a larger cord—that is wider—is generally better. Next select a span or distance from the transom. Most applications do well with a 9" span and will not benefit greatly from a larger span—the cord has a greater effect on trim. A larger span is can be used successfully for applications with limited space such as boats with two or more outboards or outdrives. Below is a table to give you a quick reference for the suggested trim tab size for your boat. When using the table consider that the ideal installation will position the trim tab at least 8" from the center of the outboard or drive unit and at least 4" from the chine. If the tab recommended in the table below will not fit within these parameters, you may consider a trim tab with a longer span.
