We've got a 2007 228 with an old Raymarine A65 gps/sounder combo. That unit has been great for us, and we had the dealer install it when the boat was purchased. I recently won a new Raymarine Dragonfly Pro 7 at a CCA party and would like to put it to use in addition to the old unit. The Dragonfly has CHIRP and will also store around 3000 waypoints vs 999 on the old A65. The new unit is very simple to install, just plug and play. I've got no issues installing the new transducer or the unit itself. Where i need some advice is on running the wire from the transducer up to my electronics box at the helm. Did Grady pre-install any chases I could use, or am I on my own here?
