An assembly facilitating the adaptation of a specific trim tab system to another, it replaces components of a Bennett trim tab setup with those compatible with a Lenco system. This allows boat owners to switch brands without requiring a complete overhaul of the existing trim tab hardware installation. For example, a vessel equipped with Bennett actuators might experience failure. Rather than replacing them with identical units, an operator could opt for the reliability or features offered by the alternative brand by utilizing this purpose-built solution.
This adaptation offers multiple advantages. It allows boaters to upgrade or modify their trim tab systems without incurring the extensive costs associated with a full system replacement. This is particularly relevant considering the historical prevalence of Bennett systems and the subsequent desire of owners to transition to newer, potentially more durable or technologically advanced Lenco products. The ability to reuse existing mounting points and wiring can lead to significant savings in both time and money during the upgrade process.
With a foundational understanding established, this article will now delve into the specific components typically included in such an assembly, installation considerations, and factors to consider when selecting the appropriate option for a given vessel.
1. Actuator Compatibility
Actuator compatibility forms the linchpin of any successful transition from a Bennett to a Lenco trim tab system. Without it, the entire endeavor collapses, rendering the conversion kit an assemblage of useless parts. The original Bennett system, relying on hydraulics, utilizes actuators designed for a specific pressure and flow rate. The Lenco system, in contrast, is electrically driven, with actuators operating on voltage and current specifications fundamentally different from their hydraulic counterparts. The assembly must, therefore, either adapt the electrical signals to the Lenco actuators or, at a minimum, provide physical mounting points that ensure the Lenco units can effectively replace the Bennett components without compromising structural integrity. A failure to address this core element directly precipitates malfunction. The trim tabs may fail to deploy correctly, respond sluggishly, or simply not operate at all. The effect on vessel handling could be severe, potentially leading to instability, reduced fuel efficiency, and compromised safety.
Consider a scenario where a boat owner, lured by the promise of simplified maintenance with electric actuators, installs a conversion kit that lacks proper actuator adaptation. The Lenco actuators, designed for a specific range of motion, might be overextended when mated to the Bennett trim tabs. This overextension places undue stress on the actuator mechanisms, leading to premature failure. Conversely, if the mounting points are not precisely aligned, the actuators could bind, creating excessive friction and drawing excessive current. In a more extreme case, the incompatible setup may result in damage to the transom where the trim tabs are mounted, requiring costly repairs to the boat’s hull. Such instances emphasize the practical importance of ensuring precise matching or successful adaptation when installing a conversion.
In sum, actuator compatibility is not merely a technical detail; it constitutes the very foundation upon which the entire conversion rests. It involves a thorough understanding of both the hydraulic and electrical operating principles, precise engineering to ensure physical and functional compatibility, and rigorous testing to validate the performance of the converted system. Overlooking this facet introduces a range of operational hazards and economic pitfalls, negating the intended benefits of the conversion, and potentially costing more in the long run. Therefore, a prospective user should prioritize actuator compatibility above all else when evaluating a Bennett to Lenco trim tab alteration.
2. Mounting Adaptability
Mounting adaptability serves as a crucial bridge between legacy hydraulic systems and modern electrical counterparts. When considering a change, the existing physical infrastructure presents both limitations and opportunities. The ability to reuse existing mounting points transforms what could be a costly, labor-intensive endeavor into a more streamlined modification. The careful consideration of mounting requirements is essential for a successful system change.
-
Hole Pattern Alignment
The legacy Bennett systems have established hole patterns on the transom. The adaptation to Lenco requires the new system to either directly align or provide an adapter that ensures a secure fit within the existing holes. If this alignment is off, new holes must be drilled, potentially compromising the structural integrity of the transom and increasing the risk of water intrusion. Cases are documented where improper alignment led to stress fractures around the mounting points, necessitating expensive repairs.
-
Transom Angle Compensation
Transom angles vary between boat designs. A Lenco actuator might have a different angle requirement than the original Bennett actuator. The conversion solution must accommodate these angular differences to ensure the trim tabs operate correctly. An incorrect angle can lead to reduced effectiveness of the trim tabs, or even cause them to bind, hindering their ability to adjust the boat’s attitude.
-
Actuator Stroke Length
The stroke length, or the distance the actuator travels, must be carefully matched. A mismatch in stroke length will translate into an inability to achieve the desired trim tab deflection. Too short a stroke, and the boat will not respond adequately to adjustments. Too long a stroke, and the trim tabs may overextend, risking damage to the system. A fitting example is a case where the boat was unable to correct listing due to an improperly matched stroke length. The tabs did not extend far enough to provide adequate lift.
-
Material Compatibility
The conversion components must be constructed of materials compatible with the marine environment and with each other. Stainless steel hardware is typically preferred to prevent corrosion. Galvanic corrosion can occur when dissimilar metals are in contact, leading to rapid deterioration. The selection of appropriate materials is paramount to ensuring long-term reliability and preventing failures due to corrosion. A common example is aluminum corrosion after improper or lack of maintenance, because of galvanic corrosion.
These mounting adaptability considerations collectively determine the ease and effectiveness of the adaptation. A poorly designed solution can lead to significant complications, negating the advantages of switching to a newer system. Therefore, meticulous attention to mounting details is paramount when considering an adaption.
3. Wiring Harness Integration
The shift from hydraulic to electric trim tabs, epitomized by a move from Bennett to Lenco, hinges fundamentally on wiring harness integration. A seemingly simple swap of actuators belies a complex electrical conversion. The original Bennett system relied on hydraulic lines to transmit pressure, dictating the movement of the trim tabs. Conversely, Lenco systems employ an electrical network, where wires convey signals to activate and control electric motors within the actuators. A successful adaptation must effectively bridge this divide, repurposing or replacing the original wiring to suit the new electric paradigm. Without meticulous attention to wiring, the entire conversion is destined to fail, rendering the new actuators inert and the vessel’s handling compromised. Consider the case of a seasoned fisherman who upgraded his boat’s trim tabs, only to find the new system unresponsive. Upon investigation, it was discovered that the wires had been incorrectly connected, preventing the actuators from receiving the necessary signals. He had to rewire the entire system.
The implications of poor wiring extend beyond mere functionality. Improper connections can lead to short circuits, potentially damaging the actuators or even causing a fire. Moreover, corrosion, a persistent threat in marine environments, can quickly degrade poorly installed wiring, leading to intermittent failures and unreliable performance. A vessel owner, after completing a seemingly successful adaptation, found his trim tabs behaving erratically during a storm. Saltwater had infiltrated a poorly sealed connection, causing corrosion and disrupting the electrical signals. The trim tabs began to function randomly, significantly reducing the boat’s stability in the rough seas. This example underscores the necessity of using marine-grade wiring, proper crimping techniques, and reliable sealing methods to ensure the long-term integrity of the electrical connections.
In essence, wiring harness integration is more than just connecting wires. It necessitates a deep understanding of electrical principles, marine wiring best practices, and the specific requirements of both the original Bennett system and the new Lenco components. While actuator compatibility and mounting adaptability address the physical aspects of the conversion, wiring integration ensures the system functions as a cohesive, reliable whole. Neglecting this critical facet invites a host of problems, ranging from simple system failure to potentially hazardous electrical events. Careful planning and execution of the wiring harness integration is the key to a successful and safe adaptation.
4. Hydraulic to Electric Shift
The migration from hydraulic to electric trim tab systems signifies more than just a change in technology; it represents a fundamental shift in operation, reliability, and maintenance philosophy for boat owners. The following considerations highlight the key differences and implications of this transition within the context of upgrading from a Bennett hydraulic system to a Lenco electric system.
-
Elimination of Hydraulic Lines
Hydraulic systems inherently rely on lines that can leak, crack, or become damaged over time. Replacing these lines can be a messy and recurring task. The shift to electric systems eliminates these lines entirely, reducing the potential for leaks and the associated maintenance. This is exemplified by a charter captain who, after switching to electric trim tabs, no longer had to deal with the constant inspections and occasional replacements of hydraulic lines, saving him both time and money.
-
Simplified Wiring
While electric systems introduce wiring, the wiring is generally simpler and more direct than the complex network of hydraulic lines. This can lead to easier troubleshooting and repair. A boater who had always struggled with diagnosing hydraulic issues found the electric system straightforward to understand and maintain, referring to it as “a breath of fresh air” in terms of simplicity.
-
Faster Response Times
Electric actuators often provide faster response times compared to hydraulic systems. This can improve boat handling, particularly in rough conditions. A competitive fisherman noted that the quick response of electric trim tabs allowed him to make more precise adjustments, gaining a competitive edge in challenging weather.
-
Reduced Power Consumption at Rest
Hydraulic systems often maintain pressure even when not actively adjusting the trim tabs, consuming energy. Electric systems only draw power when actively in use, reducing overall power consumption. A long-distance cruiser observed a noticeable reduction in battery drain after upgrading to electric trim tabs, allowing for longer periods between charging.
The decision to embrace electric trim tabs over hydraulic ones highlights a trade-off between established technology and emerging innovations. By understanding the facets associated with the “Hydraulic to Electric Shift,” boat owners can make a more informed decision about upgrading their trim tab systems.
5. Control System Interface
The narrative of a trim tab adaptation from Bennett’s hydraulic embrace to Lenco’s electrical precision finds its climax at the control system interface. This juncture represents the point where human intention meets mechanical execution, where the operator’s commands are translated into the vessel’s altered attitude. Without a coherent interface, the most advanced actuators and meticulously adapted mounting systems remain inert, mere potential unfulfilled. The tale is told of a seasoned yachtsman who invested in a complete conversion, only to discover the new Lenco actuators responded erratically to his existing Bennett control panel. The integration had been overlooked. Buttons intended for incremental adjustments triggered full deployments, rendering the system virtually unusable. The boat, instead of gliding smoothly, lurched violently with each attempted correction. This exemplifies the critical role a properly configured control interface plays in translating the promise of enhanced control into tangible reality.
The challenge lies not merely in making connections, but in ensuring accurate communication. The electrical signals emanating from a Bennett control unit, designed to modulate hydraulic pressure, differ significantly from those required to drive Lenco’s electric motors. The conversion, therefore, often necessitates a signal translator, a device that interprets the original commands and converts them into a language the Lenco actuators understand. A further layer of complexity arises when considering feedback. Some advanced control systems offer real-time displays of trim tab position. Implementing this feature requires sensors and communication protocols compatible with both the actuators and the display unit. The absence of such feedback deprives the operator of crucial information, reducing the precision and intuitiveness of the system. The pilot is left to infer the trim tab position based solely on the vessel’s response, a method prone to error, especially in dynamic sea conditions.
In summation, the control system interface is the linchpin in any conversion. It is the translator, the mediator, and the facilitator of seamless interaction between captain and craft. Overlooking this aspect, however technically advanced the rest of the adaptation, undermines the entire endeavor. The story of the yachtsman serves as a cautionary reminder: a carefully considered and properly implemented control system interface is not merely an accessory, but an indispensable component of a successful transition.

-
Material Selection for Longevity
The success of any “bennett to lenco conversion kit” hinges on the judicious selection of materials. Stainless steel, marine-grade aluminum, and specialized polymers stand as the primary bulwarks against corrosion. However, the devil resides in the details. The specific alloy of stainless steel, for instance, can drastically affect its resistance to chloride attack. A vessel owner, boasting of a successful adaptation, soon lamented the premature failure of his trim tabs. The culprit: stainless steel hardware of insufficient grade, succumbing to the corrosive embrace of seawater.
-
Galvanic Isolation: A Critical Imperative
The juxtaposition of dissimilar metals within a “bennett to lenco conversion kit” necessitates stringent galvanic isolation. Zinc anodes, dielectric sleeves, and specialized coatings serve as sacrificial guardians, diverting the corrosive current away from vulnerable components. The neglect of this principle can lead to accelerated corrosion, particularly at the interface between the Bennett legacy system and the new Lenco elements. A marina mechanic recounted the tale of a boat where the aluminum transom plate showed alarming signs of corrosion only months after the adaptation, a direct consequence of inadequate galvanic protection.
-
Sealing and Encapsulation: Barriers Against the Elements
The marine environment, with its relentless assault of saltwater spray and humid air, demands robust sealing and encapsulation. Connectors, wiring, and actuator housings must be impervious to moisture intrusion. The application of dielectric grease, heat-shrink tubing, and specialized sealants forms a crucial line of defense. The memory lingers of a coastal cruiser whose electric actuators sputtered and failed mid-voyage. The autopsy revealed that water had seeped into the actuator housing through a poorly sealed wire gland, corroding the internal components.
-
