Purchased a new 18 ft. Lund Alaskan and would like to know location where you placed your transducer on the transom of a similar boat? The Lund has 1. a drain plug slightly protruding and 2. a drain with a rounded screen that protrudes about an inch beyond the transom right in the middle keel area which is the lowest part of the transom. With these obstructions, it would seem to make it difficult to place the transducer with side imaging on the same even plane or slightly higher than these obstructions. Or maybe it isn"t a problem because these obstructions would only be slightly lower than the same plane of the transducer bottom and not interfere. I would welcome any and all comments on what you think or did (placement) to make your transducer work properly with similar problem on your boat.
Thanks, Iowafuzz
