Default RE: Thunderbolt with RCMK S-520 Inline

Tom,
Those are incredible speed numbers!! I can't even imagine that!! My 520 is stock out of the box. I am running just over 70 mph with it now. After adding a little more weight and a slight strut adjustment I am not blowing over anymore. I am very happy with the performance and handling of the boat. It is a blast to drive!
