Mr. Pike,
There's not really an "easy" method to install the transducer. It's not real difficult either. Just follow the instructions with the unit. Read them several times until you understand the theory and go by the old construction rule "measure twice, cut/drill once". The bracket that holds the transducer is designed to give you a little leeway in adjusting the transducer. I would make sure that the bracket is placed so that you think the proper setting will be in the middle of the bracket, then you'll have the greatest amount of adjustment available when you mount it. I've installed 2 on my 170CC so far and several more on other boats. I found that when I got over the fear of drilling a hole in the hull of my boat that I became more confident in the installation of electronics, stereo's, etc. As with everthing else that you "stick" on our plastic boats, make sure you use plenty of elastomeric sealant. The instructions usually tell you where not to put the transducer, but I try to get a few feet behind the boat , look at the transducer after mounting it and make sure that it points straight down so that you're not marking fish 50 feet to your left or right in deeper water. Look in the mods section and you may find some pictures that other owners have posted of their installation. Good luck!
