I just got a Spring launch request from my dealer and one of the options was "Summerizing" the boat which I declined. My understanding that this is simply running the engines and generator to suck in water that pushes the antifreeze out of the water system. For the water tank running all the faucets until all the pink stops coming out and then refilling with water and perhaps flush the system again. For the holding tank the first pump out will take care of it. Did I miss anything?:huh:
