An Armor Plate is designed to protect the transducer from side to side as well as front and back impact. The Armor Plate takes the place of the factory transom mounting bracket.  If the Armor Plate is installed anywhere other than on the transom, for example on the set back wall, some shimming may be required if the angle needs to be adjusted.  Warning: We do not recommend the Spring Back Bracket and Armor Plate on the set back wall.  It could reduce the flow of water to the engine.

An Armor Plate is also designed to attach to our Spring Back Bracket # SBB-5 for all around transducer protection.   If an Armor Plate breaks, which has been attached to the boat without a Spring Back Bracket, it has no warranty whatsoever

It is very important that you complete the questionnaire in full when ordering any of our products.  The information you provide will help us to assist you better and avoid a delay in shipping your order.
