Last season when we got the 340 I found this piece of Starboard roughly 12"x 18" long with a aluminum key mounted to the top of it. Didn't have a clue what it was for. The door broke off the central Vac system. When replacing the broken Vac. outlet I removed the seat cushions and pulled out the extension for the bed. There that odd piece was and then it hit me. Now the other thing I found a pink long round thing that vibrates when you push on the back of it is a whole other thing.I never seen something like this that ran on ten D cell batteries and had 12 speed settings and sounded like a 9.9 merc. on high.
