In the dim and distant past, the 2" thru-hull had the autohelm
Z092 transducer..about 40mm in dia.
Well after a lightning
strike and an intermittent transducer for some time its now deceased and pushing up daisies.
So, unless someone has magical ideas of where i can find a hoarded Zo92 transducer, I need to retrofit a newer transducer (E25025) into the boat. These are 35mm in dia, yet use the same hull
hole dia as the original (2").
Has anyone ever retrofited these trasnducers into an older thru-hull?, say by using a sleeve or pipe?.. if you know these transducers you will know what i mean.
Otherwise i am into taking out the old thruhull when i haul this fall..and of course, its not easy to get to.
