took out my 550 today and boy was that ducer epoxyed pretty good . first I used a dermal to grind away the epoxy ....took awhile and ended up smacking the ducer loose. then undid the connection from the head base and ended up cutting the ducer wire so I could fish it thru all those zip ties. tomorrow i'll prep the location for the ducer and install the 596.....i'll try the wire feed it thru the conduet if I can if not i'll just tie it to the conduet and under the gunnel to the head bracket.
