An inboard motor is a marine propulsion system for boats.
Its based on the state you live in but in most states the only boats the need to be registered are boats that are powered by mechanical means such as outboard, inboard or even electric trolling motors.
You should run your boats power ventilation for 30 seconds at least in order to eliminate fuel vapors in the bilge.
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.
Its purpose is to circulate air through engine and fuel tank compartments.
