Lowrance Elite-5 HDI rigging question

[philr21]

Being in Korea I can't just run down to West Marine or Boaters World and find something that works.

Have the Elite-5 HDI. Nice fishfinder, love it. Even without the downscan, the larger screen and resolution is a great upgrade over the 4.

For the large blue transducer and power connectors, want to run the cable through the hull. What sort of waterproof/clam through hull do I need to get for these large connectors?

Would this work best? http://www.westmarine.com/webapp/wcs...7#.Usq8p3kVJCg

Or something like this? I don't think the connector will fit through here?

Or maybe this thing? http://www.kayakfishingsupplies.com/...clam%29/Detail

Thanks in advance.
