Commodore marine 670 through hull transducer

 After some information of anyone who was done a through hull transducer on a 670 commodore. 

I just picked up a 2007 commodore attitude 7000 and it has a m260 linked to a furuno 585. Works fine although have fitted my simrad evo3 and was looking at putting a SS175M in to cover all bases. 

Any help or ideas appreciated.
