Our state of the art, one of a kind engine dyno provides us with the ability to not only test our high performance upgrades, but also allows us to perform critical break-in procedures after a complete rebuild of your Yamaha. 

Being able to run your power head under a load with a full diagnostic system hooked up is an absolute game changer in trouble shooting a running issue.  Instead of trying to run around the lake or river for hours on end, fighting traffic and water conditions, etc, our dyno is a completely controlled environment.  This saves the customer in extra diagnostic labor and a much higher chance of fixing your Yamaha.
