Trim Tab Operation (Continued)
The attractive surface appearance of stainless steel cannot be regarded as completely maintenance
free. Our 304 Series Stainless Steel may in fact stain, discolor, or accumulate a layer of surface
contamination (dirt and grime) during the normal course of the life cycle. Minute particles of dust
and rust may adhere to the stainless steel during shipping, installation, or storage at OEM or retail
locations. Also, please remember that some types of stainless steel fasteners tend to “bleed” over the
tabs and onto the boat. To achieve maximum corrosion resistance, the surface of the stainless steel
must be kept clean and free of all of these contaminants.
• Bennett recommends an acid and water solution to clean the tabs.
• Mary Kate’s On & Off Product is a good choice. Biodegradable, but please follow the
manufacturer’s instructions before applying.
Painting your Bennett stainless steel trim tabs and actuators
Painting your tabs and actuators with marine antifouling paint will discourage marine algae or growth
from adhering to these surfaces.
• Please follow the instructions supplied by your choice of marine paint suppliers.
• When applying paint to the actuators, be sure that they are in the fully retracted position.
• Do not paint the stainless steel ram above the area that is exposed when retracted.
Sacrificial anodes for your Bennett stainless steel trim tabs
Do not paint under the anode or the anode itself.
Stray Currents
Be aware that stray currents in your marina or in a visiting marina can cause damage to your trim tab
blades if not protected by sacrificial anodes.
• The addition of anodes on each tab will deter electrolysis.
• Do not paint under the anode or the anode itself.
• Check Anode condition frequently. Replace when necessary.
