Owner's Manual (keep with boat owner's information) Proven Durability. Unmatched Boater Satisfac tion.
Superiorby Design Congratulations, you are the owner of the finest trim tabs available. Bennett Trim Tabs provide you with control never thought possible. Properly sized trim tabs get you up on plane quickly and correct listing at nearly any speed, regardless of weight distribution or sea conditions. These benefits add up to less drag on the hull, reduced engine stress, increased speed and decreased fuel consumption. If you have any questions not answered in this manual please feel free to contact us! www.
How to UseYour Trim Tabs Getting and staying trimmed Most boats “break over” (get on plane) at a particular speed. This speed is determined by weight distribution, water conditions, etc. Bennett Trim Tabs enable your boat to plane at speeds lower than natural planing speed. By pressing the control to the “Bow Down” position, your trim tabs move down. This will raise your stern and lower your bow, getting you up on plane faster, usually increasing your speed.
How to UseYour Trim Tabs (continued) Running in Rough Water When running in a chop or heavy seas, press “Bow Down”. This will bring the “V” of the hull in contact with the waves rather than having the waves pound the hull and your passengers. In a following sea or when running an inlet, the trim tabs should be fully retracted for maximum control and maneuverability. Correcting for a List Bennett Trim Tabs may be operated individually so that you can correct for listing.

SystemSpecifications (continued) SYSTEM component specifications Trim Tabs: Stainless steel Actuators: Upper hinge material (Part #A1103) made of flexible nylon. Remainder of actuator made of high impact fiberglass-filled nylon. Hydraulic Power Unit (HPU): HPU draws approximately 18 amps (broken-in) and operates on 12 volts DC (except 24 volt HPUs). Approximately 22 ounces of ANY TYPE AUTOMATIC TRANSMISSION FLUID (ATF) is required to fill reservoir to proper level for single actuator installations.
SystemInformation Bennett Trim Tabs are built to rigid quality standards. However, the marine environment is harsh. So, in the unlikely event a malfunction occurs, here is some helpful information: 1. If trim tabs do nothing … no movement … no sound from HPU: • Inspect for blown 20 amp in-line fuse in helm control’s orange wire. • Inspect for disconnected or corroded connections on HPU ground wire, orange positive wire from helm control, and quick-disconnect plug. 2.
SystemInformation (continued) MAINTENANCE • Periodically, check fluid level in HPU. With trim tabs completely retracted, fluid level should be about 2" from bottom of reservoir (approximately 22 ounces). To refill, remove lexan cover and filler plug located at the front left hand corner of the reservoir. FILL WITH ANY TYPE AUTOMATIC TRANSMISSION FLUID (ATF) ONLY. Brands or types of ATF can be mixed. Running HPU with an excess or lack of fluid will not cause damage to the trim tab system.
OtherBennett Products Tab Position Indicator (TPI): The Tab Position Indicator is attractive, compact, water resistant and easy to install. The helm display accurately shows deflection percentage of each trim tab, and the LED brightness is adjustable for any lighting condition. Compatible with all Bennett Trim Tab systems, the TPI is as durable as it is precise. All sensors and wiring are fully enclosed within the trim tab system and protected from the marine environment.
OtherBennett Products (continued) External Line Connection Actuator: The External Line Connection Actuator is used in cases of inaccessibility inside the transom. Unlike the standard actuator, the external line hydraulics enter the transom by means of external tubing above the waterline. Recommended only when necessary. Hatch Lifter: The Hatch Lifter system raises hatches at the press of a switch — up to 250 lbs. Operation is smooth and quiet.
OtherBennett Products (continued) Auto Tab Retractor (ATR): The ATR automatically retracts trim tabs when boat’s ignition key is turned to the “off” position. Retraction prevents trim tab damage for trailered or dry storage boats. Available in 12 and 24 volts. Performance Sport Tabs: The Sport Tab series (ST9, ST12 and ST16) is engineered for the demands of offshore attitude correction over a wide range of water conditions. Built for speeds up to 60 mph.
BennettWarranty Bennett Trim Tab systems in the United States carry a five (5) year limited warranty against manufacturing and defects. Bennett electronics (Tab Position Indicator, Auto Tab Control, Electronic Indicator Control, and Auto Tab Retractor) carry a three (3) year limited warranty against manufacturing and workmanship defects. Please note: Damage to the trim tabs due to electrolysis and damage to the finish of powder-coated trim tabs are not covered by warranty.
