Thanks all, I made the mistake of epoxying the transducer in place under the v-berth while the boat was on the hard last fall. I wasn't able to test it until the WICR in Arizona in February. Of course it didn't work at all. I think I didn't get it forward far enough. I didn't know about any steel plate in the area. Fortunately I have been able to pop the transducer off without damage. Apparently the 'ducer's slick surface did not give the epoxy a very strong grip. I will be launching the boat for the season in a week or two and will be able to experiment with locations. I'm thinking centerline, under the v-berth, as far forward as I can reach from the forwardmost access opening. I'm not adverse to cutting a new access hatch farther forward, if anyone thinks this is adviseable. The transducer, by the way, is specifically designed for "shoot-thru" applicatioons.

Henry,
Check with a magnet on the 'keelson' strake on the centerline of the hull forward of the intersection of the stub portion of the keel to see if you have steel knockouts in the area - - if you find a clear spot, try temporarily mounting there, as the transducer will be forward of the keel and you will get readings (esp. in shallow water) that will coincide with 'real time' depths - ahead of the keel/board, This location is also out of the way of the convenient storage bin area below the cockpit sole near the companionway FWIW.
My speed transducer is mounted thru the hull about 6 to 7+ inches ahead of the keel stub on the C/L and I had to drill thru steel -it ate almost 3 good Lennox bi-metal hole saws!! Check first and see if you can get a reading.
Our older boats have the ballast spread along the keelson area fore and aft from my experiences with #316 and the older (steel ballast) models. Lead ballasted boats 'probably' have less ballast in the keelson strake? Jerry can chime in here....
I never ran aground til PaintBoy was sailing the boat at Havasu one year - - been 'bumping' once or twice a year ever since - funny how that goes!?! {;>)
Have fun, Go Sailing, GO

Hi Henry, On my '88 M17 there is a cavity at the aft end of the keel trunk. I placed my depth sounder transducer there and submerged it in a few inches of water. Works well.

I know this has been discussed before but I can't seem to find the references. Where is the best place to mount an interior "shoot thru the hull" depth sounder transducer on an older M17? Pictures and/or measurements would be appreciated. Thanks!
