I believe mine were located slightly to starboard due to easy access, not 
because there’s anything special about one side or the other.

Ditto on the Green. The further you get from centerline and keel, the more 
distorted your readings are likely to be.

The depth sounder on my 42 Custom is approximately where your green marker is, 
which is what I believe Bill referred to.  As Bill noted, mine is to starboard. 
 Contrary to what Bill said, mine is located just forward of the solid glass.  
When I replaced my speed and depth transducers several years ago, I used the 
same location.  Water from the balsa core literally ran down my arm when I 
removed the old transducers and pushed on the soaking wet balsa core.  We dried 
out the entire area and created solid epoxy “plugs” larger than the old holes 
for redrilling the new transducer holes.  This was not a difficult job, but 
then again I have a “stick boat.”

 

A 1982 C&C 25 didn’t come with speed and depth transducers?

Hi all,
Sorry about ressurecting this topic. I only had time to go to the boat this 
past weekend. Bill, the boat is a C&C 25 

Here is an "annotated" drawing from Sailboat data that I will use for my 
questions: https://imgur.com/a/3Ar35Pb 

To me, there are three options (some easier than others) to cut the hull (2 
inches round) and add the transducer:

Red marker: At the moment, the original (I think?) depth sounder is located in 
the red marker *inside* the hull.

Yellow marker: There is a small access port to the fibreglass on the yellow 
marker that *could* fit the depth/speed transducer. It feels very high on the 
hull and a bit fragile as the fitting would stick out of the access port and be 
a bit exposed (second picture of the link)

Green marker: Last option, cut a square access *hatch* on the plastic liner 
wall (orange mark) that separates the "inside" of the boat from the fiberglass 
hull and then cut a hole on the green mark.

Any mindhive thoughts? I am very nervous about making a hole in the wrong place 
:)

Thanks!

Not sure which model you are referring to, but most often they are just ahead 
of the keel, but off to one side several inches, usually SB, I think .  There 
should be a section adjacent to the centerline where it is solid Glass before 
it goes up onto the balsa.

Hi Folks, 

I bit the bullet in this year's boat show and bought a wind/depth combo from 
Garmin. New electronics since 1982 on Spice. 

 

Im having a bit of a hard time finding where to place the transducer (airmar 
depth, speed, temp). Manual says ahead of the keel but access on the 25 Mk II 
seems limited.

 

Anyone around here has any tips? 

 

Cheers
