Hello guys, I just purchaced a Garmin FF 140. I have a 1986 Bayliner I\O. My question is this: After I drill the 1" hole for the massive connector plug, what is the best way cover the hole? I'm going to fill it with silicone, but to my disapointment, Garmin didnt ship a grommet or any type of cover. My bro-in-law purchaced the Garmin GPS, it uses the same transducer and he got a plastic cover for the hole. Any ideas???
Thanks
Brandon
