Taking Yanmar Training north!
We recently held our first-ever Yanmar training in British Columbia, Canada, covering Yanmar VC10, VC20, VC30 control systems, as well as how to properly use the Yanmar SA-D diagnostic tool.

It was a great opportunity to bring hands-on technical training directly to our Canadian Yanmar dealers and continue expanding support for the Yanmar marine network.

A special thank you to our Yanmar dealer, Stem to Stern for allowing us to use their facility to host this training, and thank you to everyone else who was able to make this training a success!

Thank you to the OCC students for taking the time to visit—we enjoyed having you and hope to see some of you out on the water (or in the marine industry) soon!
