Transducer mounting

Hi all I've just bought a honwave 3.2 and I want a mount my
Transducer for my fish finder somewhere on the boat now I'm thinking on the Transom,
Am I likely to get interference from the engine?
I don't really know anything about the engines but can I power the fish finder from the engine or do I have to use my 12 volt battery as I would in my kayak?

Thanks Russ

You will be fine on transom with transducer but you will need battery for fish finder

You need to know if your engine has a charging circuit fist Russ if you have conect to a battery a 20 amp hour will be enough get a gel one maintenance free Lucus do one around £20. Transom mount your transducer keep it away from the keel mines about 6 inches it needs to be level with the hull and set horizontal to the water not the hull you will get a decent bottom echo up to about 6 mph then turbulence kicks in you will still get a depth reading but not much else having said that if your looking for fishing spots low speed is nessasary

I've fitted them to every transome of each boat I've ever owned and never had any issue even with them directly infront of my outboard ( had to fit one there at one point). My sidescan transducers are always fitted directly to the hull just infront of my outboard to give best side to side imaging. My transducer shows good clean images even at 40kmh in depths of 250+ metres.

Old model hds and the newer hds gen 3 on my boat.

Great echoes jonp never had anything like that on my SIB too much disturbance from the soft hull I'd have to look but my lowrance I think states no nearer than 4 inches from the keel line to avoid the bow wave of the engine leg affecting the echo

Remember these 3.2 Honwave’s have the extended airdeck at the transom.
