Pics welcome if you have them.. thanks!!!!

Probably pretty easy to make one. Depends on the size of your boat though. I found drilling a hole and marine grade silicon to be quick, simple, and effective. But this was on a deep-v.

You're options are:

1) Clamps (as described above)

2) Adhesive a 'Ducer board (3M 5200 may actually make this possible, though not as robust as bolts)

3) Drill Baby Drill

Option #3 on my boat done by the dealer. I feel it's the cleanest option, but you want to make sure the silicone is rated for below the waterline and was applied liberally.

I've honestly heard that the 3M 5200 gives a really good bond. So much so that it's really hard to remove.

Yep the 3M stuff is great!!! I'll shot a couple pics of my Ranger when i get home and share what I did...

You could get the suction cup mount.

Cheap and easy way to to it and have it also be removable so you can use it on multiple boats is to get a piece of wood 2x4, 1x6 or similar and cut to the height of the transom and clamp it on. May not be the most secure and could possibly move, but I've used this before and it worked well.

Didn't someone used to make a transducer mounting thing that attached by plugging into the drain hole? Or is this another figment of my fevered imagination?

[Dale Rueber]

If you decide to drill, do yourself a favor and get a plastic transducer mounting board. That way if you remove/change/add a transducer you are not putting any more holes in your transome, only the 2 original holes to mount the transducer board.

Hunterjoe went with the peice of wood using a c-clamp to hold it down. haven't tried it out yet but it seems sturdy. now just going to look for a battery, thanks.

where do you find marine grade silicon?
