[CA] [CA11] must transducer be on startboard side?

[the Brain]

well I could install a tiller kicker to simplify a port side mount.
still undecided on tiller or binnacle still researching.
I’ve picked the 2013+ Suzuki 15HP electronic fuel injection.

Vessel’s hull is aluminum 22’ (add 20” main engine bracket) 75” beam 45” transom 1800LBs old pocket cruiser

I'd like to know how much setback will keep the starside mounted kicker engines prop wash from interfering w/ transducer also on starside like is there a rule of thumb.thanks Chuck for quick reply
