Anyone with a Garmin ?

Ok so I picked the 546 last night and it looks great, best 200 bucks i have spent so far. I will be ordering the transducer today in hopes of getting it in before next weekend. Question, can anyone reccomend to me the best spot for the transducer on my transom ?

There are a few general rules about location for transom mounted transducers:
1) make sure it's not mounted behind a clamshell through-hull. The turbulence from the clamshell will keep the transducer from performing when on plane.
2) Keep it as far away from your engine's lower unit as practical so shock waves from prop blade rotation won't cause interference.
3) Mount it deep enough so it runs in clean water when on plane or it will only work at displacement speeds.
4) Avoid mounting it just outboard of a step or strake in the hull, or it won't run in clean water on plane.

Left side vs right side shouldn't matter.

Thanks Blue, so basically the location of the one in the first pic would be the best spot for the new one. When I remove the old ones do I just fill the old holes in with 5200 or should I do something else ?

The location of the original transducer may be a little close to the engine. As Big Lew mentioned, the Garmin installation instructions should give you some guidance on minimum distance. If Garmin says it's ok, you should be good.

On the holes for the old transducer and speed sender, 5200 will work, but if you can drill them out a little and pump some thickened epoxy resin in them that would be a more permanent solution.
