Boat Leveler Hydraulic Trim Tab System 18" x 9"
The Packate include TRIM TABS, MOTOR, PUMP,
BRACKETS, CYLINDERS, HOSE, CONTROL, WIRE HARNESS, ROCKER
SWITCH,AND OIL.
12 gauge 304 stainless steel trim tabs are available in standard
and custom lengths. They are guaranteed against electrolysis,
remaining strong and secure. Insta-Trim's hinges prevent most
spray and can be used for transom or bottom mounting.
Insta-Trim Boat Leveler tabs are two stainless steel planes
installed on the
transom. As the hydraulic cylinders deflect the trim tabs, water
flow is redirected.
This waterflow creates upward pressure under the trim tabs,
raising the stern.
As the stern rises the bow lowers (figure 1). Because proper trim
tab surface
area is essential, larger and/ or slower boats require larger trim
tabs than smaller
faster boats.
Insta-Trim Boat Leveler Tabs employ the force of hydraulics for
smooth
trimming action. When the trim tab rocker switch is pressed,
electrical current is
sent to the hydraulic motor pump unit. This signal activates the
electic motor,
creating fluid pressure. Valves on motor pump unit open,
channeling the
required amount of fluid to the actuators. When the trim tab
rocker switch is
released, the valve close, capturing the fluid in the actuators
hydraulic cylinders.
Thus trim tabs hold their position.
Insta-Trim Boat Leveler Tabs operate in reverse of what you might
think. The
port trim tab lifts the port stern which lowers the starboard bow.
With
properly installed trim tabs, you will not be as aware of this
reverse function as the
control functionis based on the direction you wish to move the
bow.
The proper use of Insta-Trim Boat Leveler Tabs becomes very easy
after a
short time. Here are some general guidelines to get you started:
Getting and staying trimmed
Most boats "break over" (get on a plane) at a
particular speed. This speed is determined by weight distribution,
water
conditions, etc. Insta-Trim Boat Leveler Tabs enable your boat to
plane at
speeds lower than natural planing speed. As the throttle is
pushed, the stern
squats and the bow rises (figure 3). In short bursts, the trim tab
rocker switches
are pushed in the "BOW DOWN" position, moving both trim tabs. The
boat
reacts as the stern rises and the bow "breaks over", resulting in,
among other
things, increased visibility and speed (figure 4). If over
trimming occurs as the
boat gains speed, the rim tabs can be retracted by pressing "BOW
UP".
(When overtrimmed, the boat plows, reducing maneuverability).
Features:
Wiring
- Color-coded wiring in 25' to 40' lengths with quick connects
fittings, meets federal standards for heat, pull and insulation,
making installation easy.
Solenoids
- They are custom designed for Insta-Trim Boat Leveler Co.,
epoxy sealed and humidity resistant, thereby preventing shorting
out. The solenoids lock the tabs in any position, eliminating
driftback. Barb type hose fittings provide tight, secure
connections.
Motor
- A powerhouse with coated wirings and a thermal overload that
resists temperature and amperage build-up. 1 3/4" stack windings
and top mounting eliminated oil leakage. The motor is mounted
with stainless steel nuts and bolts, and is easily disassembled.
Brackets
- Swivel type brackets allow cylinders to be mounted an
adjusted to any angle. Knockout pins act as shear pins it tab
strikes an object.
Pump
- Designed and engineered exclusively by Instatrim. The
built-in bypass is factory set at 400 P.S.I. tolerance held to
.00025. Amperage doesn't exceed 16 because the unit circulates
oil, rather than stalling out or trying to pump additional
pressure.
Motor Cover
- 4 1/2" D x 6" W x 11"H, high impact ABS plastic cover with a
built-in oil reservoir mounts easily with two screws. The filler
is located in front. Our cover protects the motor from
occasional wash down.
Cylinders
- Impact resistant, fiberglass reinforced nylon cylinders
eliminates expansion and resists ultra-violet rays. Two
expanding type seals, plus O-ring, eliminates high and low
pressure leaks. Barbed cylinder fitting and an inserted tubular
rod prevents hose blow-off and breakage.
A stainless steel spring retracts the cylinder when the boat is
not in motion.
Trim Tabs
- 12 gauge 304 stainless steel trim tabs are available in
standard and custom lengths. They are guaranteed against
electrolysis, remaining strong and secure. Insta-Trim's hinges
prevent most spray and can be used for transom or bottom
mounting.
Hose
- Designed and manufactured exclusively for Insta-Trim with
nylon-reinforced webbing and protective PVC coating. Rated at
2000 lb. burst pressure, 15' of hose is supplied for your
system. Entering the transom 6" above the water line, the hoses
are held securely with hose trim.
Stainless steel clamps hold the hose to barb fitting at the
solenoid.
Rocker Type Controls
- Mounted on the dash they are easy to operate. 2TP Micro
switch with silver contact points adjust the tabs for maximum
control and performance.
One pint of Insta-Trim biodegradable transmission oil, funnel and
mounting hardware is supplied.

How Insta-Trim Boat Levelers Work
| Insta-Trim Boat Leveler tabs are two stainless steel planes installed

Safety Precautions
*Do not overtrim, particularly at high speeds, as the bow will dig in
and wave action may cause the boat to veer.
|
*While Underway, do not move one trim tab significantly farther down
than the other as undesirable listing could occur.
|
*Use your trim tab rocker switch with caution.
|
*For best maneuverability, trim tabs should be fully retracted in a
following sea or when running an inlet.
|
*Improper use of trim tabs can cause accident or injury
|
*make periodic checks of hydraulic lines, switches, wiring and fluid
levels, looking for corrosion, fatigue and proper oil levels.
|
| Insta-Trim boat leveler tabs have significant effect on the operation
and versatility of your boat, and nobody knows your boat better than you.
So the best learning method is to spend time getting familiar with your
boat's reaction to the trim tabs. As your experience with insta trim boat
leveler tabs increases, so too will you enjoyment. Always operate your
boat with safety first in mind, "It's Smooth Boating Ahead"!!!! |
How to Use Your Insta-Trim Boat Leveler Trim Tabs
The proper use of Insta-Trim Boat Leveler Tabs becomes very easy after a
short time. Here are some general guidelines to get you started:
Getting and staying trimmed
| Most boats "break over" (get on a plane) at a particular
speed. This speed is determined by weight distribution, water conditions,
etc. Insta-Trim Boat Leveler Tabs enable your boat to plane at speeds
lower than natural planing speed. As the throttle is pushed, the stern
squats and the bow rises (figure 3). In short bursts, the trim tab rocker
switches are pushed in the "BOW DOWN" position, moving both trim tabs. The
boa reacts as the stern rises and the bow "breaks over", resulting in,
among other things, increased visibility and speed (figure 4). If over
trimming occurs as the boat gains speed, the rim tabs can be retracted by
pressing "BOW UP". (When overtrimmed, the boat plows, reducing
maneuverability). |
| While learning to use trim tabs, begin buy pressing the
trim tab rocker switch (figure 5) in half second bursts for gradual
trimming. A momentary delay occurs from the time the trim tab rocker
switch is pressed to the time the boat reacts. To avoid overtrimming,
allow enough time between bursts to permit the boat to respond to the trim
tabs. This time depends on the boat's speed. |
| A good way to learn your boat's optimum attitude is to
conduct a test by running lightly loaded at a fairly high speed in flat
water. During this test, observe the bow in relation to the horizon. This
situation should reveal the boat's best running attitude. Then, under
normal operating condition, use the trim tabs to reproduce the same
attitude achieved during the test. You will know the ideal attitude by the
diminished wake, reducing laboring of engine(s), and the increased
rpm's...all at the same throttle setting. When running in a chop or
heavier seas, press "BOW DOWN", positioning the bow to cut through the
waves. This action provides a drier, more comfortable ride. In a following
sea or when running an inlet, the trim tabs should be fully
retracted for maximum rudder response. When steering from a
bridge or tower, a good trimming method is to watch the bow spray or stern
wake and the roostertail. In an untrimmed condition, the spray from the
bow is far aft on the hull, the wake is high, and the roostertail is
pronounced. When trimmed, the bow spray is farther forward, the wake is
reduced, and the rooster tail is smaller and farther behind the boat. In
addition, when trimmed, the rpm's increase. |
Correction of a List
| Insta-Trim Boat Leveler Tabs are operated individually to
correct a listing condition. The trim adjusts the boat's attitude in the
direction the trim tab rocker switch is pressed. If the port bow is high,
press the left-hand "BOW DOWN" direction on the trim tab rocker switch and
the port bow lowers (figure 6). If the starboard bow is high, press the
right-hand "BOW DOWN" direction and the starboard bow lowers. Do not think
about what the trim tabs are doing; just concentrate on your trim tab
rocker switch. Note: The boat should be trimmed fore and aft before
correcting for a list. |
Using Trim Tabs with Power Trim
- Adjust the trim tabs to achieve planing attitude.
- Use the power trim to position the prop path parallel to the waterflow
- If necessary, re-adjust the trim tabs to "fine tune" (figure
7).Insta-Trim boat Leveler
Tabs let you get the most out of your power trim because the trim tabs are
trimming the hull while the power trim is trimming the prop.
Correction of porpoising
Press "BOW DOWN" in half second bursts. As
the trim tabs deflect, porpoising subsides and speed should remain the same or
increase. Only a slight amount of trim tab deflection should be necessary.
