  • Step 3 - You will be contacted when your repairs have been completed and to arrange payment and return shipping.

NOTES

  • Part numbers shown in bold have new Flight Systems replacements in stock for same-day shipping. Certain older OEM boards can no longer be rebuilt due to obsolete parts for which we offer new replacements and are denoted as "NEW ONLY".
  • TEST ONLY - There is a test fee of $35(slightly higher for complex ATS controls). Boards received that test as "NTF" (No Trouble Found) are charged this fee.
  • Factory Direct Prices Shown - RE-SELLERS (Gen Set, Marine & RV Dealers/Distributors/Repair Shops) call for your Discounted Pricing!
  • "P" = PLUS PARTS. Required components over $10 each are extra charge, will be itemized on the invoice. Other required components and material are included in the rebuild price at no extra charge.
