insane 20' seacraft w/ twin 2.3l Mercs on bracket

[boatless]

this spring at the toll booth for the sunshine skyway bridge (goes across tampa bay) i spotted a 20 seacraft that looked to have twin merc outboards, light grey in color i think. i was like 4 lanes away and got caught up in traffic ahead of this rig and couldn't get a better look. i know it was a 20 seacraft, but with twin's! my only thought was HOLYSH!T.
