I temporarily mounted my DST800 triducer on the port side under the icebox using a blob of wax from a toilet bowl wax o-ring. It's kind of like sticky playdoh. I've been using it that way for the last 6 months and it works fine.
One advantage of mounting inside the hull is that it is easier to get the sensor pointing straight down.
I am now in the process of trying to properly mount it.?While the depth portion works fine shooting through the hull, the paddlewheel that measures speed through water doesn't work so well embedded in a glob of wax and mounted inside the boat.
?I've removed the old transducer that was installed on the starboard side in the locker under the seaberth, and am going to install the new sensor in its place.
The deadrise is pretty close to the edge of what the sensor will support, so I am thinking that I want to add a fairing block or something to level it out -- I am still researching options. One tempting option is to layer on some fiberglass to create a 'pocket'. See attached.
