Has any one successfully installed a in hull depth transducer in a Skater. I really don't care about high speed readings, just idling in a cove or near shore. Also, connection to a NMEA system, i.e. Mercury Vessel view? Location, coring the core, etc.? Temperature readings would be cool, but I don't like the idea of putting a hole thru the hull. Thoughts?

Taboma,
You can use an in hull transducer but there are a few things that need to happen. One is that it will not work shooting through the coring in the hull. The person installing it would need to do a core out. Second it would have to be fwd of the first step as close to the bottom as possible You will need to epoxy the housing with west systems or glass the housing to the hull. Our experience with sealers/5200 etc eventually leak. We normally use antifreeze as the fluid as it is easy to see if it leaks. Make sure you adjust it for the proper angle.
Option 2 would be to use a thru hull style that is flush mount with the hull. this will provide temp of the water too. You could mount it high enough on the deadrise that when the boat is at speed it would not be in the water and affect the performance of the boat.
Both styles need to be a NMEA 2000 smart sensor and would tie into the gps backbone. If you need anything further send me your number and I will give you a call.
I work with Marine Electronics for a living. Hope this helps.
