555's were used in a lot of different heavy construction vehicles and farm tractors. You might try a repair shop that works on construction vehicles, they may have someone that is familiar with VT555's. They are not a high revving engine, my mechanic says keep it below 2100 RPM and it will last forever. We hit 8.5 knts at 1900 with our single 555
