Drain Plugs-07 Avalanche

[lyonboarder 4]

I had my boat winterized last October.  The shop is now claiming they forgot to invoice me for a broken drain plug that they replaced. Apparently the broken drain plug is plastic and blue in color.  I have only the stock center ballast tank.  I am only aware of the following drain plugs on this boat:

1.  Transom drain plug-brass

2.  Engine bay drain plug near the tranny-Brass with t-handle

3.  Ice Chest-expandable rubber screw down drain plug

Are there any other drain plugs on this boat related to winterization?

You have 6 blue plugs on that motor and water pump.

Thank you. I think those 6 blue plugs are "freeze plugs."  Is that the correct term?  Are they typically removed during winterization?  This was the first time I had to winterize my boat as I moved to a cold climate.
