Most cruising boat engines are inboards, but some use stern drives or outboard engines, too. Mounted beneath the cabin sole, and like a car or truck, marine engines have transmissions that help shift the engines in and out of gear, as well as reducing the revolutions to a speed usable by the propeller, which they are linked to with a stainless steel shaft.
