HB side imaging transducer location

I'm mounting a HB side imaging transducer on a older v-hull fiberglass boat with 140 Mercruise in/out board drive unit. Can I mount transducer in front of Propeller which would give clear shot both sides and bottom? If not how far off centerline must I go? saw where, were mounting transducer to jack plate on out board units. Thanks in advance.

You are going to have to mont it off to the side. Mounting in front of the prop will create turbulence in front of prop. Prop will slip and cavitate causing it to burn off edges of blade.
