Boris, No doubt that the GEN III Will be a Excellent Flow meter. I just returned from Florida Winter Nats & I see more boaters using your Flow meter Racing the Twin Nitro Classes. Many of these current Twin Engine boats run a fixed Needle that is not a Third channel type fuel valve, so the balance left to right engine is very critical. The Boris Flow Meter has improved the TWIN HYDRO Racing. Many Boaters running consistant & racing hard together with a consistant Needle setting.. A large percentage return to the bank today running. Reguardless if you run a Single Engine Boat or a Multi Engine Boat the Boris Flow meter is a MUST HAVE Tool for tuning todays High Nitro Race Engines......... THANKS for your input & the continued support of a Great Product & another Generation of the BORIS FLOW METER.... jw
