Marine Dynos

At Grand Sport Center, Inc., we want to ease the mind of our prospective buyers regarding the performance of their boat. By providing a dynometer test with every purchase of a boat, we load test the drive and engine to ensure proper running condition at the time of delivery. Each dynometer test is performed by Certified Technicians and completed in front of the purchaser, demonstrating the operation and validity of the boat. Team GSC runs the dynometer over 200 times a year reassuring  a quality sale for the buyer and seller.
