Ted,
,, Commonly called "In Hull" or "Shoot Through" transducers, they will
work on a Catalina 27. That is, in most places inside the boat.
There's a ton of advice about the method of Mounting an IN HULL transducer.
Just do a GOOGLE for "In Hull mounting" to see them.
Really, they break down into two variations.. Glued or Oil bath..
1. GLUED:....... Epoxy or Silicone (I've heard of using Marine GOOP too)..
PRO:
Easy and quick to mount,... Silicone (and GOOP) relatively easy to remove (I
did a silicone method, worked fine)
CON:
Mounting unlikely to be VERTICAL (sound cone tipped), Hull MUST be solid
fiberglass-No voids,...
Glued area MUST be very Clean with NO bubbles in the glue, Epoxy hard to
remove.
2. Oil Bath.. Methods of mounting Numerous !
PRO:
Transducer can be vertical, No worry about Voids in liquid. Oil can be any
cheap light weight oil (cooking oil or Mineral oil)
CON:
If it leaks-MESSY!, Requires Mechanical device (Pipe or container) to hold oil
and transducer, Stands High requiring Head Space,.. Once set up, difficult to
move.
