I�m possibly getting a used Garmin 73SV and the transducer that is with it is the long bar shaped one, I believe the model is GT30-TM. I want to mount this up at the bow and use it on my trolling motor but I�m not sure if I can. I�ve seen the Garmin trolling motor adapter but I haven�t had any confirmation that it will work with that particular transducer. At almost $300 for the �proper� Garmin trolling motor specific transducer I�m really hoping that I can adapt the transducer that will come with the unit to work.....any help with this?

So I had to call shield and saver and the only way to mount the GT40-TM, which is actually what I have not the GT30, would be to cut the skeg off of the TM, use the saver plus another part to put it all back together, so around $290 of parts.
Unfortunately there really isn�t much of another option, the smaller GT52-HW is not compatible with the non-Chirp unit.....any other ideas?

I have the GT30 and put on the transom and love it.I can read it even going 30 mph.

Go to the garmin forum at bass boat central and they can help out a lot

The only issue I have with that is I do use 2D sonar in conjunction with the DV and SV. So not having that will be problematic for me....

there is a transducer that has 2D for your unit. It is the GT20. Make sure if you have a 8 pin connectorit's a 8 pin transducer. Call garmin to make sure

Check on the GT22 it fit my 12volt Tm and no need for special mount

2D sonar and Down scan

To keep the SV capability I have only one choice and that is to use the CV40-TM that I already have. None of the other ones that have been suggested allow to keep full functionality.
I ended up ordering the TSS kit which has a replacement skeg for my TM because I will end up having to cut off the factory one.....I was between a rock and hard place on this deal unfortunately. I�ll post up some pics when I get it installed, it�s actually a pretty well engineered deal, I just was hoping to avoid cutting on my TM.
