Just looked it up, I got the 80 inch long one thinking that was what I needed. Now I know I would go with the 61 inch. (The cable actually travels less than if it were going to the transducer). I ruined my firewall grommet, so be careful with that. If I could do that over again, I would pull the grommet off first, then feed the new cable through it, then remount the grommet.
