Used mostly by walleye fishermen, the big motor gets you there but is too big to troll at the speeds required for walleye rigs. The usual is to put a 9.9hp "kicker" off to one side of the transom. It does make an effective get-you-home motor if the big one dies. The tiny Honda on the back deck looks like a tender engine. That is a TON of $$$ though, Honda outboards are top dollar.

I got nuthin' for you on that radar setup though, I'm thinking SG is right on that. It was a good deal that was "adapted" to the application. Hard to tell from this angle but there may be a place to mount a small platform in line with that and use it make microwave popcorn too?
