Bennett Trim Tabs 42 X 12 4212 with No Control
Description:
Bennett Trim Tabs are designed and manufactured with pride at the Bennett Marine plant in Deerfield Beach, Florida. Every Bennett system carries with it an accumulation of nearly 40 years of research, development, and testing and is designed to provide years of dependable service.
Every trim tab is sheared and bent not welded. Welding alters the properties of stainless steel which invites corrosion. Bennett actuators feature patented through-hull hydraulics. There are no vulnerable external hoses to decay. Plus, every Hydraulic Power Unit is tested by both person and computer to insure this reliable unit deflects the trim tabs, holds firmly during use, and retracts smoothly.
Do It Yourself Just a few hours and some common tools are all that is needed. Components of the Bennett system are designed and packaged with the do-it-yourselfer in mind. Every kit is complete, featuring one page step-by-step instructions, with templates. Our new M80 and M120 Sport Tabs even come with an installation video.
Many factors affect the choice of properly sized trim tabs, and the ultimate responsibility for selection is up to the boat owner. These sizing recommendations are based on average performance. Your choice may vary based on power, engine configuration, weight distribution, type of boat, and use. When making a choice between trim tab sizes, remember that the largest trim tabs that will comfortably fit on the transom will be the most efficient.
General Guidelines
Choose at least one inch of trim tab span (per side) for every foot of boat length. (Examples: 22 foot boat = no less than 24" x 9", 36 foot boat = no less than 36" x 9")
Span = side to side measurement
Chord = fore to aft measurement
Measuring
After choosing a general trim tab size (see chart below), double check the size by measuring the transom using the diagrams. When measuring, disregard the strakes and follow the Vee of the hull.
12" Chord
The 9" chord is used in most applications. However, in certain applications the 12" chord may be more effective: Limited Transom Space Boats with twin outboards or twin I/Os, or boats with transom configurations that limit trim tab span can use 12" chord tabs to achieve maximum lift in minimum area. Using the measuring guideline above, fit the maximum span trim tab and use the 12" chord. Extra Lift Slower boats (less than 15 mph), semi-displacement hulls, boats over 50 feet, outboards on brackets, or boats with any other feature that increases the need for lift aft benefit from the 12" chord. The 12" chord provides greater surface area, thereby utilizing more water flow and providing more lift.
