means A boat driven by an engine rather than sails or oars, built for speed and direct control.

from A straightforward compound of 'power' (from Old French 'pouvoir,' to be able) and 'boat' (from Old English 'bat,' a small vessel). The word itself arrived once internal combustion and steam engines made engine-driven boats common enough to need a name distinguishing them from sailboats — a plainly descriptive 19th/20th-century coinage, no hidden story, just function naming itself.
