2005 2120 with 2016 Etec 225 (460 hrs). No trailer. Located in Long Beach CA. Fresh Simrad suite- NSS evo 12, w/ radar. Fresh radio with AIS. New stereo, all networked. Off shore bait tank. 15 rod rocket launcher. Profish windlass.
I have a
2005 2120SC and there was an aluminum plate bonded to the underside of the deck where the pedistal bolts down. I had two stubborn bolts that had to be drilled out. I drilled and tapped all of them to the next larger size. The holes in the pedistal easily accommodates a larger bolt.
When I broke my antenna off I replaced it with a removable Shakespeare 6225r and used the same coax. I broke the mast apart with pliers so I could get the entire coax. On the now bare end of the coax I used a:
Shakespeare 3003.4061 PL-259-CP-G Marine Center Pin Connector,Gold.
The system works...
