Aluminium-Alloy Trim Tab Systems...

The hydraulic cylinder of this second series is always a double acting one in painted brass with a stainless steel cylinder rod. They have external hosing.
Only the MY4001 model is a double acting cylinder in bronze and stainless steel without external hosing. What generally changes throughout this series is the shape and dimensional details of the tab.

As regards the system composition there are two possible solutions. The difference is the type and the quantity of the electro-hydraulic power unit.
It's possible to install a single solenoid power unit together with the relative electrical wiring kit, as on the system with stainless tabs; otherwise two separate reversible power units, each of them with an electric inversion kit.

Normally on very fast boats the second optional is preferable, while the first is usually adopted when the electro-hydraulic power unit must control other functions, too and not only the tabs. The schematic of both configurations are shown below.

Trim Tabs - in stainless steel with single or double rams to suit boats up to 35m. Five standard plate sizes, or custom built. An electro-hydraulic power pump required (12/24V)
