Thru-Hull Transducers

[smokeonthewater]

my montecarlo has a 3/4" and 3 2" ducer holes in the bottom along with a few seacocks as well...... I plugged 3 of the ducer holes with bronze thru hulls and pipe caps and used the 4th for a ducer



On SEVERAL other boats I have glued a normal transom mount ducer inside the hull with epoxy. It is IMPORTANT to mix the epoxy slowly to avoid bubbles and If you do this on the sloped portion of the hull you also need to build a small dam out of modeling clay to pool the epoxy enough to level the ducer and to hold the ducer level till the epoxy sets up.

when done this way, the temp reading will be within a couple degrees of actual.
