This can't be bob... too intelligent sounding.

The electrolysis will be ghastly. That unit uses the bronze casing as
electrical ground for the transducer and also attempts to isolate it from
battery ground noise by some filtering circuitry. The case ground and
battery ground will not be at the same potential and will cause floating
ground electrolysis.
Use a transducer that sends through the hull.

I'm thinking of adding a Ray 365 Fishfinder to Alien. I can get one new
with a
bronze thu-hull for 169.00.
It does speed, temp and depth, but the bronze thru hull protrudes from
the
hull
with the fairing block and that sort of bugs me. It's a great deal
though...
Comments??
