Tim White
would like to exchange H201 toward purchase of H301

Hi Heatercraft, customer brought in his boat last week to have the H201 installed. Once I gained access to the blower unit it was obvious the H201 wasn't the core needed. I would like to return this one and pay the difference needed to purchase the H301. Does your 15% restocking fee apply in this instance? Thank you for your help. Tim White/Inboard Solutions/[****]
