I am looking for advice on mounting the transducer for a Humminbird Helix 7 Mega SI GPS G3 on an 18ft Bowrider with Mercury 4.3L I/O. Has anyone done this successfully on such a boat? Photos of your installation would be very helpful. I don’t want to buy this Sonar without some idea of how useful it will be. I certainly don’t want to keep drilling holes in the boat to try different locations.
This sonar is a high resolution Sidescan (with Downscan) fishfinder with GPS.
The Sidescan has special mounting problems because it sends a horizontal beam out each side. Depth sounders and Downscan Sonar are easy to mount, but not a Sidescan…
My boat has 8" between the transom and the front of the lower unit and 24" from transom to the center of the prop.
I am looking for advice from someone who has installed a similar sidescan unit.
