know this is a really old thread but wondering if rjames had any luck getting his display working again. I have a new gauge I purchased from GLS last winter, I hooked it up and only got the two dashes he speaks of. I wonder if he ever replaced the transducer or is it possible to service them. I have read that they have water in them, could it just be that the water has gone out of it and it needs refilled. I have no idea where the transducer even is, anyone know where they put them on the 2800SCR, mines a 98 model

The transducer is either mounted on the exterior of the transom or in the engine compartment forward of the engine. If in the engine compartment it is bonded to the inside of the hull and if the bond is broken an air barrier is created resulting in the transducer from seeing the bottom and the display shows the two dashes. In some installments water is used at the bond to ensure a good sound joint.

thanks for the info. I'll have to take a closer look inside the engine compartment when I get to the boat next. I don't believe it has an external unit.

It will look like a hockey puck.

yeah, I've seen a few pictures, I'm guessing if it's damaged there probably won't be a replacement available to work with the replacement gauge I already bought. Probably looking at a whole new unit.

The one I purchased is this one Airmar http://www.imarineusa.com/AirmarP79-RCA.aspx which you fill with antifreeze, so is liquid filled and I glued to the hull with 3m 5200. It works great so far, but if I was to do it again I would try to find a puck based one that you simply glue to the hull, with no liquid filling, like the original one. I also have a depth finder attached and I didn't know where to put the transducer, so put it way in the back in front of the drain plug, which is always wet, and placed a bag full of shot lead on top of it to hold it in place with plans to eventually find a place to glue it, and have never gotten around to gluing it down, because it works great as it is.

The digital depth gauge I purchased is this one http://greatlakesskipper.com/standar...r-finder-gauge. I have a feeling they will eventually go out of stock so now have an extra one.
