GIBY is now a Cummins Dealership!

Great Island Boat Yard is now a Maintenance Level Cummins Engine Dealer, as well as a Maintenance Level Onan Marine Generator Dealer.  This dealership gives our technicians access to world class Cummins and Onan Technical Training, and allows us the rights to use a Cummins/Onan diagnostic laptop to troubleshoot even the most complex engines and generators in the Cummins family.  Our techs are very excited to be at the forefront of Electronic Diesel Technology.

  • We’re in the process of becoming certified to handle maintenance, warranty and repairs on Cummins QSB 5.9, QSB 6.7, QSC 8.3, QSL 9 and QSM 11 Electronic Engines, as well as the older Mechanical Engines and Zeus Drives.
  • We’re also working towards certification in the full line of marine Onan Generators.
  • This means we’ll now be able to offer our customers full service and parts support for ALL Cummins and Onan products.

“REPOWER WITH NEW”
