Changing Transducer in the Water

I changed out my old OEM transducer today while in the slip. I was very apprehensive about this task. However, as far as boat projects go, this was the easiest and fastest one. @dtfeld had been previously been to help and we determined it was stuck and not going to move without some help from the bottom. I had a diver come today and equipped him with a 6” piece of 1.25” dowel, a hard plastic hammer, and a $4-toilet plunger. I went in the bilge having previously lubed up the new DST810 good. I also had the blanking plug there with me also. One tap from the diver meant he was ready and then one tap from me meant go. I was to tap twice on the bottom when I was done. When he saw the transducer move upward, he was to place the toilet plunger over the hole. From his one tap to my two taps, was no more than 8 seconds. He tapped the transducer twice and it shot 1/2 way out with the o-rings still holding back any water. I pulled the old one out expecting to see some sort of geyser, but to my surprise, there was none. I might have vacuumed out 1/2-3/4 cup of water. The new one slipped in with almost no effort and the cap tightened down securely. The older model boats/transducers do not have the valve in the housing and mine did not either.

Hope this helps someone. Just have everything ready and go for it.

Makes you feel good when things go right!

They are made to be pulled and the speed gear cleaned while in the water. Pull it, put your hand over the housing, and install the blanking plug. Clean or change the paddle wheel and reverse the operation. It seems a lot more daunting than it is. Having done it, I would not hesitate to do it again.
