Hi Chuck

I seem to have 3 options here

Option 1 place the rv 220 set forward, where the head through-hulls are and move those back a foot or so. This will move the transducers below where the helm is, see linked photo.

This location will experience a higher likelihood of being out of the water in moderate and above seas when planing. (moot point if these only work at trolling speeds as the faq seem to indicate) I am assuming trolling speed is 8-10 mph or lower?

Option 2 is to locate the pair in the stern and relocate the live well/ wash down water intakes aft or out bord of the transducers. I will still have to deal with the potential of the head through hulls disturbing the water.

Is there a hierarchy of location preferences in relation to through hulls? i.e is outboard of the transducer preferred to inboard?

Regarding general placement:
Is farther back on the boat preferred to closer to the bow

Does clean water at trolling speed trump a more aft location?

I have seen the diagrams on placement but they do not include discussion of forward through hulls.

Option 3

Place the transducers between water intakes and the transducer flats, link below

I am concerned that the inlets may cause problems, partly because they are inboard of the transducer. I would think air will migrate to the surface from the keel up so any transducer inboard of an intake would be less likely to have aerated water interference.

One last question, I have an existing dsm300 with a B744v transducer. Will I be able to use this with the Axiom pro? Can I connect directly to the Axiom or do I need to use the dsm 300? Are and adapter cables needed?

Thanks
