Marine Dynos

Here at Grand Sport Center, Inc., we want to take the hassle and guess work out of buying a used boat. By providing a dynometer test on every boat purchase, we load test the drive and engine to ensure proper running condition at the time of delivery.

Each dyno test is performed by Certified Technicians and completed in front of the buyer, demonstrating the operation and integrity of the boat. Team GSC runs the dynometer on every boat we sell and every boat we take in trade, reassuring  a quality sale for the buyer and seller.
