I have a 350 model with the transom transducer. 4 years ago I wanted to mount it in hull.
I cut the flaps on it and trimmed it down. It sits in a vessel sikaflexed to hull. The water in vessel covers the sounder.The vessel is ally sheet and the hull is single skin glass about 6mm. There is a slight rake where transducer sits, though it has not bothered cheaper transducers.
It works well 99% of the time. Good in deep. The only scenario is that it loses bottom, if going in sand when water is dirty. I am trolling slow speed with an outboard and boat is 18ft.
In 5 to 10ft it repeats it's last reading for up to a minute. It will find bottom again , usually in anything from 15 to 30 ft. That is where I don't want to be. This is a sandbank I am fishing.
Never does this on rough ground. Coloured water and sand only. Weed growth on the bottom just now and it will be up in about 6 weeks. I know this is a transom transducer. What are the real differences between the material and build of my transducer and an in hull version.......apart from facilities. Surely they don't make the transom mount intentionally less sensitive? I thought it was just the difference of a wheel log.
