First of all, THANKS for your service in the sand box! Good to have ya back in one piece.
There are a number of threads here talking about unwinterizing a boat. It really depends on what your dealer did to it in the first place. You may have a bag of parts that need to be reinstalled? ie; knock sensor, drain plugs, etc. Some guys leave the hoses loose, ie; like around the thermostat, heater & shower? Some leave the impeller out? Some disconnect the batteries?
Like Lee said, probably a good idea to hook it up in the driveway first. Then drag it to the ramp.
