V1 (a rental) loaded up with 3 occupants reversed out of its dock into the Tavernier Creek Marina basin.  V1 then forced the throttle hard forward causing it to launch towards the V2 that was unoccupied and secured at the dock.  V1 forced the throttle even harder in forward in an attempt to steer away and avoid striking V2.  The starboard side of V1 ramped over the lower unit of the center outboard engine of V2 braking off a section of the anti-cavitation plate.
