The short answer is no. Boats are made with outboard, inboard-outboard, a hybrid using an inboard engine driving a stern mounted shaft that looks like the lower end of an outboard. Others use inboard engines, typically larger cruiser and specialty ski boats. Personal watercraft use a inboard engine powering a water jet pump. This jet drive system is also used in some boats. Most smaller boats are powered by outboards. New large outboards up to 400HP permit larger boats some over 30 ft long to be outboard powered. Most mid-size boats from 18-30 feet are powered by inboard-outboard systems to take advantage of larger automotive engines.
Most speed boats, especially with outboards, use gasoline engines. Larger vessels such as ships and commercial boats, generally use diesel. For raw power and performance, gasoline engines are still best. Big chevvy V8s are popular choice for powerboats with internal engines. Water and electrics (for the spark) do not mix well, so gas engines need to be maintained and looked after well and can be temperamental. For economy and reliability diesels are best. Which is why commercial vessels use them.

American football and Nascar are two sports in which flags are used.
Johnson and Evinrude outboards, use the model number, rather than the serial number, to determine the year model. Mercury outboards, uses serial number and horsepower.
