Some additional comments Harry: One big issue to keep in mind is the Transducer has to be mounted in a Level Position. On the side of the hull that has curves means you have to build a 'fiberglass mounting shoe' (see photos). This is not easy for the average person. You might consider hiring a pro to do the installation. Big issue number two is you might have to have a bigger battery. Etc... It might be worth doing a small unit and clips on the stern. Just angle it forward a bit. If anyone wants to see the photos of this set up let me know and I will forward them to you. Fair winds Bob Eeg www.montgomeryboats.com (949) 489-8227

Hello Harry..Happy Holidays.
The centerboard line travels into the lead keel area and there is not a single place to mount any type of transducer.
If you want kind of a forward (advance) look I suggest you mount the Transducer in the forward V Berth locker, off the centerline, so the boat can be put on and off the trailer without the bunks scaping off the transducer.
The way to locate this 'spot' is to site down the bottom (bow, looking aft) and split the difference between the vertical side boards for the keel and the carpet covered
wood bunk board. Put your finger on that spot and drill UP with a 3/16 drill bit. (but first, pre-measure forward enough so you know the hole will be in the V berth locker.
Take a look inside; notice the hole isn't in a FLAT area, no worries. On and inside only transducer just follow the instructions. On a model that requires a mounting hole (usually about 1 inche or a little more) you are going to have to lay in some glass mat over the little hole and build that area up flat enough for the big plastic NUT on the backside of the transducer. After build up, drill out the 3/16 hole from below with a hole saw. (keep it level).

Harry, I am sending you a series of Photos of a recent installation of a Sonar Type Transducer.....it was quite large and don't assume the pointy end goes forward...it doesn't.....hahah...yes, we mounted it facing aft by mistake.
You will see the size of it in the photos and you can spot the location of it by the outside photos with the M_15 on the trailer.
I can send you some Fiberglass material (mat/clothe) at no charge if you need some.
Can't send resin or catalyst these days without a hassel. Get that from West Marine.
Fair winds and Hi to Nancy..!

Randy: Thanks very much for your prompt reply regarding placement of the transducer.Do you know if threading the cable could be done through the same hole that the line to the swing centre board occupies. If so, then I could mount the transducer farther forward on the outer side of the hull,to enable a more advance warning of rocks- a foreword-looking sonar beam. Also, I think I'll buy the Garmin unit.Thanks again, Randy, and also to others who helped. Not to be out done by our good Yankee friends,since Dec.1,the temp. has hovered between -4F and -10F.
