What I mean by a little bit, my experience was about 1/8" higher. With that said the transducer at it's lowest as it relates to the hull(in my case the right side) is still about 1/2 the thickness of the transducer below the hull. If I would have had more time I would have looked for a piece or 1" thick starboard instead of the 3/4" just to gain that little extra rise in water off the hull. But all in all I am very happy that it performs the way it does.

I just added a Garmin with the same transducer as
take a potter did in this two year old post. Tried to duplicate what he did except used 1" starboard instead of 3/4". I understood he kept the bottom of the ducer a bit below the hull. At speed it seems to work well but gives quite a vertical rooster tail splashing up to the engine cowling. Didn't have that issue years ago with my Sitex, but probably didn't have the ducer creating a dam to water flow. Anybody else got this issue or should I simply raise it a bit? Raised it within the slots in the bracket and seems to have helped slightly. Just looking for advice before drilling more holes Thanks
