About Us


Based in Upland, California, GT Performance is one of the engine building, rigging, service and parts shops you'll hear about if you spend even a little time at a Southern California or Colorado River hot spot.

Founder of GT Performance, Gary Teague didn't grow up in the SoCal boating scene, but he's been into fast boats since he owned his first one at age sixteen and drove it every weekend at Lake Nacimiento near the Central California coast.




Gary is considered one of the industry leaders in fuel injection and turbo charging technologies. If it's fast and reliable, it probably has the GT Performance name on it! Gary personally oversees every project and nothing leaves the shop until it meets Gary's demanding standards. GT's technicians have experience in building high performance marine boats and each team member is a specialist in his field.




Besides marketing our own innovative products, custom rigging and turn-key engine packages, GT Performance is also an authorized Mercruiser Parts and Service Center, and distributes top performance marine hardware, including: Autronic EFI & Ignition Computer Modules, MSD, Whipple, SX, Glenwood, Brodix, InControl, CMI, Imco, Livorsi, Dart, Crower, Carrillo and Gaffrig.
