My vote gots to the modded 700sc version of the Cen Aquajet from Off shore electrics. I've been thinking of selling off one of my nitros and getting one for myself. I miss the Traxxas Villain that I modded like crazy that I used to have. Actualy I'd prefer an electric any day over a nitro boat.

but this is a real boat though and the reef racer is much more forgiving and a whole lot slower.
