[CA] Axiom 9 transducer placement

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum echo8287,

Pontoon boats generally leave few if any options for alternate transducer mounting locations. As such the transducer will need to be mounted to either of the transducer mounting plate. Some who desire more flexibility with respect to transducer mounting will fasten a transducer mounting board (which made from Starboard and will have larger length and height dimensions than the transducer mounting bracket). Use of such transducer mounting boards permit alternate transducer mounting heights to be tested without having to drill additional holes into the boat's aluminum mounting bracket ... i.e. the transducer mounting holes will instead be drilled into the transducer mounting board. Please note that should a keel be welded to the bottom of the pontoons, that such keels may cause an aerated / turbulent flow of water to pass across the face of the transducer. This aerated / turbulent flow of water may adversely affect the performance of the fishfinder when the boat's speed approaches and/or is operating on plane. However, when operating as slower speeds, performance should not be impacted. it is generally recommended that transducers be installed on starboard side boats having a single prop.

With respect to angle of attack and with the understanding that the transducer may not support imaging while on plane, it would typically be recommended that the transducer be mounted in an orientation permitting it to be parallel to the bottom of the pontoon.
