If you need marine equipment that will stand up to the rigorous demands of a workboat, look no further. DuraPlane Marine has developed a line of trim tabs that are more resistant to corrosion than anything on the market. Our high quality, cast bronze units are constructed from the same marine grade NiBrAl material as propellers. These units are extremely resistant to corrosion and have a higher tensile strength than aluminum. The Bronze series also features protected internal cylinders that do away with exposed hoses and indicator cables. If your boat lives and works in salt water, the investment in these beautiful bronze trim tabs will pay off time and time again.
