Bennett Trim Tabs Kit 42″ x 9″ w/o Control Review

The Road Test: Bennett Trim Tabs Kit 42″ x 9″ w/o Control

For anyone who’s spent significant time on the water, especially with a vessel that’s a bit on the larger side, the quest for optimal hull attitude and performance is a constant one. My own journey led me to the Bennett Trim Tabs Kit 42″ x 9″ w/o Control, a robust hydraulic system designed to give boat owners finer command over their craft’s performance. This particular kit, from a manufacturer with a solid reputation in marine hardware, arrived as a seemingly complete solution for enhancing planing efficiency and ride comfort, minus the electronic control unit.

The impetus for this upgrade wasn’t a sudden malfunction, but a persistent desire to wring more out of my boat, particularly when cruising with a full load of gear and passengers. Dealing with a stern-heavy condition that required excessive throttle to get on plane, or resulted in a porpoising motion on calmer waters, was becoming a tiresome compromise. I’d considered other brands, even looking at simpler mechanical trim tabs, but the promise of hydraulic precision and Bennett’s established track record swayed me. My initial impression upon unboxing was one of solid engineering; the stainless steel tabs felt substantial, and the hydraulic components exuded a professional-grade feel, sparking a sense of practical satisfaction.

First Use Experience

My first real test of the Bennett Trim Tabs Kit 42″ x 9″ w/o Control occurred during a weekend excursion to a local lake, renowned for its variable chop and tendency to get crowded, making smooth handling a priority. Installation, while requiring a bit of careful planning for hydraulic line routing and wiring, was straightforward enough for someone with basic marine maintenance experience. Once installed and primed, the initial deployment of the tabs produced an immediate, noticeable difference in how the boat responded to throttle adjustments.

The tabs performed admirably in the moderate chop, allowing me to dial in a much flatter running angle, which significantly improved visibility and reduced the jarring impact of waves. Adjusting the trim tabs gradually with the manual valve (as this kit doesn’t include an electronic control) provided nuanced adjustments to the boat’s attitude. There was a slight learning curve in coordinating manual tab adjustments with throttle and steering inputs, but it felt intuitive after about thirty minutes of practice.

Extended Use & Reliability

After several months of regular use across various water conditions – from glassy calm mornings to breezy afternoons with building waves – this kit has proven its worth. The hydraulic system has remained consistent, with no signs of leaks or pressure loss. The stainless steel construction shows no indication of corrosion, even with regular exposure to saltwater spray and periods of inactivity.

Compared to the rudimentary trim provided by just engine trim alone, these tabs offer a far more effective and precise method of hull management. Maintenance has been minimal, primarily consisting of occasional visual checks of the hydraulic lines and ensuring the actuators are free of debris. The only “wear” I’ve noticed is the slight accumulation of salt residue, easily wiped clean.

Specifications

The Bennett Trim Tabs Kit 42″ x 9″ w/o Control includes two 42″ x 9″ stainless steel trim tabs, each designed to mount flush against the transom. These tabs are actuated by a powerful hydraulic pump and two hydraulic cylinders, which are the heart of the system. The kit also includes all the necessary hydraulic tubing, a fluid reservoir to maintain system integrity and prevent corrosion, and the basic hardware for mounting the tabs and cylinders.

The generous size of these tabs, measuring 42 inches wide by 9 inches deep, is crucial for effectively lifting the stern of larger boats, enhancing planing performance. The high-quality stainless steel construction is not just for aesthetics; it ensures corrosion resistance and longevity, which is paramount for marine equipment that faces constant exposure to the elements. The hydraulic system provides the necessary force to overcome water resistance and adjust the boat’s trim effectively.

Performance & Functionality

The primary function of this trim tab kit is to provide a dynamic means of controlling a boat’s running attitude, and in this regard, it excels. By deploying the tabs, you can force the stern down, lifting the bow and achieving a flatter planing angle. This significantly improves fuel efficiency at cruising speeds and enhances passenger comfort by smoothing out the ride in choppy conditions.

The performance is remarkably responsive, especially when compared to relying solely on engine trim. The ability to make fine adjustments allows for optimal hull positioning across a wide range of speeds and load conditions. Its main strength lies in its ability to transform a boat’s handling characteristics, making it feel more stable and efficient.

Design & Ergonomics

The design of the Bennett Trim Tabs Kit 42″ x 9″ w/o Control is a testament to functional simplicity and robust engineering. The stainless steel tabs are precisely formed with a slight upward bend on the trailing edge, designed for optimal hydrodynamic effect. The hydraulic cylinders are compact yet powerful, designed for easy mounting and direct connection to the tabs.

While this kit omits the control unit, the components themselves feel well-built and durable. The finish on the stainless steel is smooth, and the hydraulic lines are made from a flexible yet tough material. The overall feel is one of quality craftsmanship, suggesting it’s built for the rigors of marine use.

Durability & Maintenance

Durability is a key selling point for Bennett trim tabs, and this kit lives up to that reputation. The high-quality stainless steel is incredibly resistant to corrosion and pitting, even in saltwater environments. The hydraulic system, with its sealed fluid reservoir, is designed for long-term reliable operation with minimal maintenance.

Routine maintenance is straightforward, mainly involving rinsing the tabs and actuators with fresh water after saltwater use and periodically checking the hydraulic fluid level. There are no complex electronic components to fail, which adds to the perceived reliability. Based on my experience and the reputation of the brand, these should last for many years of service.

Accessories and Customization Options

As this is a kit without a control, the primary “accessory” you’ll need is a control unit. Bennett offers various options, from simple rocker switches to advanced electronic controls that can automate tab adjustments. The included hardware is sufficient for mounting the tabs and cylinders themselves.

This kit serves as the foundation for a hydraulic trim tab system. The 42″ x 9″ tab size is suitable for a range of medium to large-sized boats, providing ample surface area for effective trim control. While this specific kit doesn’t come with them, compatible control units and additional hydraulic tubing can be sourced from Bennett or other marine suppliers.

Pros and Cons of Bennett Trim Tabs Kit 42″ x 9″ w/o Control

Who Should Buy Bennett Trim Tabs Kit 42″ x 9″ w/o Control?

This Bennett Trim Tabs Kit 42″ x 9″ w/o Control is an excellent choice for owners of medium to larger boats (roughly 25-40 feet, depending on hull design) who are experiencing handling issues like slow planing, porpoising, or a generally uncomfortable ride, especially when loaded.
