TCM,
I have a 80# Terrova mounted on my Triton TR-186.
You can mount the Terrova directly on your bow, you will most likely have to plug your existing holes.
Or you can purchase a MK Quick-disconnect plate, this plate is mounted to your bow, then the Terrova is mounted to the plate. This would be useful if unloading/loading on a steep boat ramp.
Terrova mount does extend out from the bow and you have to be careful on steep ramps during unloading/loading not to break it on the trailer roller. Never a problem sofar on my ramps.
Terrova needs to be strapped down when running as accidental deployments in rough water have been reported. I use a simple backpacking web-type strap with a clip I got at Academy.
If you are going to use the built-in US2 sonar, you will need the Humminbird or Lowrance adapter cable for your unit.
If you are going to use a side-imaging transducer and you have Humminbird then here is an URL on running your transducer cable:

Also make sure your remote batteries are good or carry spares, as some Terrova functions like Spot-Lock, etc require the remote.
If the remote is dead, then Spot-Lock, etc are not available.
I also have the foot-pedal for fishing in stumps, better than the remote. IMO.
