Thanks CB....I may do this. I'd like to clean up my transom of all the possible points of water intrusion...don't want a soggy transom....plus I lose bottom at speed.

I cleaned a spot in the bilge and epoxied the PVC pipe and let harden. Then I laid in a bed of silicone. Very important to try to get out as much or all of the air bubbles as possible. I then set the transducer into the silicone and poured more silicone around it just covering the body of the transducer. You just want to be sure to have the transducer pointing straight downward or you'll get false depth readings.
Easy job and works well. 8)


CB...when ya put one in this way, is it important that it's done in the CENTER of the hull just over the keel, or can it go up the deadrise on one side or another(of course keepin' the transduder pointed straight down)...and the silicone you used...just the regular silicone that comes in a tube or anything special there?...

Fishfinders are like most all other things in this world you get what you pay for. Depending on your budget I would stay with furuno, lowrance or garmin in that order. I regularlly fish the washington canyon and my furuno unit reads the bottom quite well down to around 1300 foot and I can get a digital readout of bottom depth to below 3000 foot depending on the thermocline. The deepest readout was 3307 feet. The transducer is located on the transom and above 30 kts it can get erratic but at that speed I am just trying to get someplace . Its just common sense that if you shoot ultra sound thru a solid hull you are going to lose detail so mounting inside the hull is a tradeoff. The other disadvantage is that in a shoot thru
application you lose you temp and speed functions. For me temp is almost as important as contour and echos. My suggestion is buy a quality unit and try it on the outside if your not satisfied inside is always an option

Doesn't need to be in the center over the keel. Mine was roughly 8-10" offset. Just point straight down. Regular silicone is okay. 8)
