Norm: My transducer has been sitting in a puddle of 100% silicon sealant for about 4 years now. It was intended to be a test shot, but worked well, so I left it. If you don't like where it sits, you can move it. Shoots through the stuff just fine and gives a good signal. Make a good sized puddle about half in inch larger than your transducer and about half an inch high. Press the transducer down into it, working it slightly side to side to eliminate any air bubbles. Let it set about an hour or so....over night is even more better ( a highly technical term) You want to locate it in a flat spot that shoots as straight up and down as possible (a heeling boat will give you an inaccurate signal due to the change in angle), and in a spot that will be in contact with the water at all times. Mine is located about two ribs to port of the keel and about a foot forward of the bulkhead under the forward bunk. Under the cockpit would work, but that's shooting where you have been, not where you are going....all of 5 feet's worth of difference.

I am installing a Piranha 15 combination fish and depth finder in the forward locker forward of the keel slope on my M15. Can anyone recommend a non permanent material to set the transducer in? I want to test it before epoxying it in place. The hull has a slight concave well just forward of the keel slope that I am going to test. Would it better to fill the well with epoxy to make a level spot or just use the attaching material to fill the well and hold the transducer in place?

Any insights would be appreciated.

This probably will sound silly if you've never heard it before, but it's on the up and up. Try Silly Putty or one of it's generic counterparts. I have my transducer "permanently" installed with it. Been in there for 2 seasons and has never failed. I got it at Wal-Mart (generic) for $.99! Just make sure you install it over solid f-glass and you're all set.

Norm: My friend Larry Yake used silly putty for his depth sounder transducer in is M17--said it works great. That's what I'm going to use. Gary Hyde Pullman, WA gmhyde1@mac.com M17 #637 'Hydeaway 2' M15 #235 'Vanilla' On Oct 31, 2005, at 10:32 PM, nbundek wrote:
