O.K. I give up....where did they hide the water tank for the sink in an 03 288 MCOB? I have all the books that came wtih the boat but it mostly covers enngine and drive. Also how do you go about getting all the water out and should it be winterized for winter storage? I am in Indiana so we will see single digit temps?

In my 2003 32' it is under the rear seat on the far starboard side.

I didnt see a tank but i will look for a hose connection.

thanks

Lol I just got my 32 single this year and I'm having the same issue. I havent looked real hard yet but it's defiantly not in my clear sight. I just thought maybe it was taken out and never put back. Are any of you guys getting water in the sides under the rear seat. Mine doesnt have a drain hole.

If i remember correctly you have to unscrew the starboard arm rest and remove it to access the tank. The arm rest has wingnuts holding it on.
