Boat Repair/Installing a Garman Fish Finder/Depth Gauge

Question
I recently purchased my first boat. A 185 Bayliner. I need to either have the unit installed or install it myself.  The unit is around 200.00 but the Marina wants 450.00 to install.  Are these units difficult to install?  He did say it measures the depth from the Stern if that helps any.
Do you think I could do it without much of a problem?

Answer
Their should be a set of installation instructions with the depth finder when you buy it.  It isn't that difficult to install them you just have to be very careful to seal the screw holes that you drill very well.  Marine grade silicone will work but I like to use 5200.  It is a little heavier and seems to be a more permanent sealer.  If you read the instructions and have any more questions just ask.

Expertise

Basic boat motor mechanics or boat wiring. I can help the most on mercruisers, merc outboards, and johnson evinrude outboards.

Experience

Mercruiser tech. Started working on boat motors three years ago. I have limited shop time under my belt but have proven myself in our shop and am now the shop manager.

Organizations
I have a mercury tech number and a yamaha tech number if you would like, but i don't think that being a certified tech makes you a good diagnostic pro.

Education/Credentials
Three years of see and learn shop time. Two weeks of tech training at Mercuiser school at Springfield. Two update merc schools at Topeka KS. "gotta love George". Tons of "E" skills classes online. Most of my ability to diagnose came from shop time working out problems.
