Description Extended Information
 
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 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 (figure 2).

 

Benefits

  • Easily Installed - Instatrim boat levelers come preassembled with mounting hardware. They are easily and quickly installed, and a minimum of time is required.
  • Level Ride - Instatrim boat levelers put your boat in the proper trim and corrects listing, making for a smooth, enjoyable ride for you and your passengers.
  • Increased Visibility - A level ride improves the skipper's visibility. You and your passengers are more secure and boating safety is improved immeasurably.
  • Environmentally Responsible - Your smooth, level ride allows the engine to run more efficiently, increasing your milage, saving fuel and stretching your boating dollars.
  • Longer Boat Life - In proper trim you stay on a plane at lower R.P.M.'s.Your engine doesn't labor and engine life is extended substantially. Less wear and tear on your craft ensures more years of boating pleasure.
  • Improved Performanc - Your Instatrim boat levelers allow you to throttle back regardless of load and speed.

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

  1. Adjust the trim tabs to achieve planing attitude.
  2. Use the power trim to position the prop path parallel to the waterflow
  3. 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.
(IMPORTANT: READ "SAFETY PRECAUTIONS")

HINGE AND TAB INSTALLATION

Affix hinges and tabs to backside of transom with No. 10 x 1" stainless steel screws, as in figure No.1 and No.2. The three inch 3" dimension, as shown in figure No.1 is approximate and may vary, BUT ALWAYS KEEP TABS AS FAR TO THE OUTER CHINE AS POSSIBLE. Hinge may be affixed to bottom of hull if practical.

 
TAB BRACKET AND CYLINDER
Drop hex nut into recessed area on tab bracket, with lockwasher inserted on 5/8" s/s bolt. Come through underside of tab to contact nut and tighten with screwdriver to MAX.

TRANSOM BRACKETS
Mount hinge and tab up from bottom of boat 1/4" as in figure No.2. Permit cylinder bracket to rest against transom, so that trailing end of tab is straight out or 90°. This 90° angle may vary according to transome design. Mark bracket holes, drill and affix bracket with No. 10x1" self-tapping screws.

SIZE BIT
On fiber-glass, aluminum and steel hulls No.22 for a 5/32" hole wood use No.35 size bit for a 3/32" hole.
TRANSOME HOLE FOR HYDRAULIC HOSE: Drill 1/2" hole on 45° up angle 6" above waterline. Do not drill hole straight in, as this will kink hose when applying hose trim. CAUTION: Leave ample loop in hose at hydraulic cylinder as in figure No.2.

ELECTRIC HYDRAULIC MOTOR-PUMP
Mount motor-pump in VERTICAL POSITION AT ALL TIMES. Never fill above 3/4 level. It is desirable to mount motor-pump on inside of transom as in figure No.1, but as it is hydraulic it can be mounted in any convenient location. KEEP MOTOR-PUMP UP FROM BOTTOM OF BILGE SO ASNOT TO COM IN CONTACT WITH BILGE WATER OR WASHDOWN WATER.

HYDRAULIC HOSE
Kit comes with one ample hose with hydraulic cylinder on each end. After locating mounting position of motor - pump, cut hose (they may be of unequal lengths) run loose ends through one half inch 1/2" transom hole onto barb type fittings protruding out from each side of motor pump cover. Tighten hose onto barb fitting with stainless steel clamps provided. DO NOT OVERTIGHTEN CLAMPS.

WIRING
Connect color-code wires coming out of motor-to backside of switches-which are also color-coded.
RED OR HOT LINE: To get proper power, connect DIRECT to BATTERY OR STARTER
GROUND: Attach black wire to boat motor, being sure you have a good, clean, tight connection as short as possible
FUESING: Always use our 20 amp. In line in fuse which is attached to switches.

EXTRA SWITCH SET
Color-code wires from lower switch station to fly-bridge switch.

TO BLEED
After complete installation, work tabs up and down a few times, then while in the UP position, remove filler-plug located on front of oil reservoir , allow trapped air to escape, insert plug. If unit should ever need refilling use Insta-Trim Biodegradable oil or any type of automatic transmission fluid.

FIGURE No.3
On round bottom boats, mount hinge at Point A and B as close to bottom of boat as possible. Disregard curvature at point C, as our hydraulic cylinder has a ram thrust of 2 3/4"which will bring tab in contact with water.

FIGURE No.4
Mount it the same as in figure No.1 and No.2 Mount tabs on same angle as "V" of transform.
CURVED TRANSOM: Cut mahogany shims, as in figure No.5
DOCKSIDE: When boat is at dockside, It is recomended to keep tabs extended.
