Yesterday afternoon my next door neighbor and friend Frank helped me with the final piece of electronics installation which was the sounder transducer. He was kind enough to let me use his 3/4 inch bit to drill the final hole through the transom. Why are those connectors so large? The new Montauk has two rigging tunnels, one per side, and that was very helpful. The starboard tunnel was full of battery cables, hydraulic hoses, and Smart Craft & DTS cables. The port tunnel was empty and pulling the transducer cable was straight forward if not easy. I had to put a pretty hefty tug on that rigging cord even using the empty tunnel.
I flush mounted the electronics which includes a Garmin GPS/MAP740S, Standard Horizon VHF radio GX1500S, and a Digital brand 3 foot stainless steel whip antenna mounted on a Shakespeare 4 foot extension. The GPS and VHF are interconnected for DSC purposes. Thanks Tom (Bluewaterpirate) for the pictures of your similar installation and the good advice. Everything performs flawlessly. My wiring is not nearly as pretty as Tom's but it works and I can make it pretty in the Fall when it's a little cooler.
The antenna is a copy of JimH's idea for getting a small antenna up to a better height for performance. I deviated with his example only by substituting the Digital brand antenna for the Gam brand he uses. The Gam ADAP-II or ADAP-2 made a nice clean installation possible. I choose to mount the antenna assemblage atop the console. That places the antenna tip about ten feet above the deck. After connecting the antenna I monitored channel 9 for a few minutes and was receiving traffic from the Mobile River about nine miles from our house.
I plan to splash the boat for the first time this Wednesday. Between now and then I have to wash and wax the boat, load the stuff that lives aboard, charge the battery, and buy some non-ethanol fuel.
In a few days I'll post some pictures.

I am looking forward to seeing the pictures. The GARMIN 740S seems to be a very popular choice for a GPS, chart plotter, SONAR combination. I sense that its feature-to-price ratio must be at a peak point in the curve.
