Is this normal? Here's a picture of the transducer, I'm glad I used silicon sealant as the bedding compound in case I ever needed to remove it.
I have the same external tranducers mounted internal to both my boats ,both are araldited in ,both work fantastic never being upset by speed ,there is two types one has 6 pins and one has 8 ,seamark nunn have both and the expensive one is only £60 ,from my time when i was into ultrasonic flowmetering (which is similar application holding sensor on the outside of pipes ) we always did temporary checks with K-Y jelly (from boots) ,never used silicone ,maybe silicone would absorb the signal ?? maybe like when you were a kid with the two tins and a string link ,worked better when some "twang " in the string ,
