sidescan transducers

[SkunkBoat]

Anybody have a sidescan sonar with a transom mounted transducer? Does outboard motor interfere with sidescan?

I'm looking to put a secondary sonar on my Grady. Looking at Garmin 94sv. Going with Garmin because boat already has a 4208 (with a garmin24 Sonar unit and Airmar trhu Hull xducer) and I don't want to learn 2 different menus.

There are deals with included transom mount transducer $899. To use a Thru Hull I would have to purchase separately @ $850 unit+ $700 thru hull transducer(that is prohibitive!).

With the cost difference it seems I should just try the transom mount.
With twin outboards and trim tabs there is not much space for mounting.
