Boat Leveler Co. Insta-Trim
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 water flow creates upward pressure under the trim tabs, raising the stern.
As the stern rises the bow lowers. Because proper trim tab surface
area is essential, larger and/ or slower boats require larger trim tabs than smaller
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 electric 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 functions based on the direction you wish to move the bow.
