A1101EX Trim Tab System
NON-STANDARD INSTALLATION OPTIONS
External Line Connection Actuator:
One of the unique features of the Bennett Trim Tab system is the use of
concealed through-transom hydraulics. However, there are cases of complete
inaccessibility inside the transom making the use of the standard Bennett
actuator difficult. For such instances, the Bennett actuator is available with
an external line connection. The special actuator avoids the accessibility
problem by allowing the hydraulics to enter the transom at a location where
there is no obstruction.
The hydraulic tubing connects directly to the upper hinge of the actuator and
is fed through the transom above the waterline. A chrome “clamshell” is
included with each actuator to cover the hole in the transom.
The external line connection actuator is recommended only when necessary.
Part Number: A1101EX
Reduced Actuator:
The “Reduced Actuator” is used in applications where a slightly shorter than
stan dard actuator is desired. It is one inch shorter than the standard A1101
A actuator so it may be installed lower on the transom. Actuator stroke is
same as standard at 2-¼” unless otherwise specified.
Part Number: SA2118A
(SA2118EX for external line connection)
Small Actuator:
The “Small Actuator” is a scaled-down version of our standard A1101A actuator.
It is made for short transom applications or where standard actuator height
makes installation difficult. The “small actuator” length is 2″ shorter than
the standard A1101A. THE “SMALL ACTUATOR” IS GENERALLY NOT RECOMMENDED FOR USE
ON TABS OVER 24″ IN SPAN, OR FOR PERFORMANCE APPLICATIONS. The “small
actuator” is designated by 3 rings around the base of the cylinder body.
Part Number: A1200S
(A1200EX for external line)
There is no extra charge for any of the three actuators above, they are the
same cost as the standard A1101A.
Special Trimdicator or Tab Gauge indicator kits are required for compatibility
with the above actuators.
Short through-transom fitting:
For boats with limited space inside the transom, a shorter hydraulic
connection is available in lieu of the standard pipe nipple and elbow. This
short fitting allows the tubing to be connected to the actuator outside the
boat. The tubing can then be fed through the transom and pulled from the
inside. Standard pipe nipple and female elbow are not used.
Part Number for
fitting (used on any actuator except external llne): VP1146
(one per actuator)
Alternate length pipe nipples: Lengths of 2-1/2′, 4″ and 5″ are available.
(Standard pipe nipple length is 3″.)
