GE Silicone I vs. Silicone II?

That would make sense, being as the plastic "bathtup" the transducer locks into is... uh... plastic . Thanks for clearing that up.

Jim, what are you using for displays in the cockpit? I am trying to pry my wallet open to do the same project.

I'm using a Garmin 498. It's mounted on a home-brew swivel-arm that's attached to the inside cabin bulkhead on the port side of the companionway. When I want to look at the GPS from inside the cabin, I swivel it in. When we want to see it from the cockpit, it swivels out so it's sitting in the upper left of the companionway as you're looking forward.

That home-brew swivel-arm the PO made is a bit light for my GPS, which is larger and heavier than the PO's was, so I'll probably eventually replace it with one of the (more substantial) commercial products I've seen mentioned here on Sailnet before. Something that would allow us to move it actually outside the companionway entrance would be good, because, as it is, it's kind of tricky getting past it.

Btw: The Garmin 498, being last year's model, is on clearance many places. It's hard to beat for the price you can get it for right now. Comes pre-loaded with U.S. coastal and Great Lakes cartography. If you don't want the sonar, you can save a few bucks going with the 492.

I mounted my 498c on my edison pedistal using a piece of teak and some U bolts.
