Recently purchased the above triton with a small lowrance hook depth finder at the console. I purchased a garmin echomap 73sv to accompany the lowrance at the console. Once I determined the location on the transom where I wanted to mount the transducer, I noticed an piece of angle bar abt 4" long welded to the bottom of the hull just fwd of the transom. This angle is on both the port and stbd side. Anyone know the purpose of this angle bar?
