Merc BIG Tiller back order?

[115 optimax]

I bought a 115 optimax for my 1725 Pro Guide and im still waiting for the Murcury Big Tiller handle to come in.Its been on back order since January and the dealership isnt sure when it will be in.Shouldnt Mercury stock pile these handles or how does this work.Ice is going to be gone xtra early and i dont want to be last one on the lake.Any info would help. Thanks......
