Can a inboard engine be used in a car?

Depends upon the type of inboard engine and the type of car.... inboard engines can differ from car engines when it comes to fuel injection system or the carburetor's, motor mount placement, pollution control accessories or sensors, cooling system set up, air intake positioning or intake manifolds, exhaust manifolds, starter positions left or right side and the computer control system (if equipped.) Marine engines can also differ from car engines by the way they are set up such as the camshaft,crankshaft,lifters,valves,timing and balancing so you will need to know all the engine specifications of both engines to see if they would be compatible to swith them out... The late model inboards such as used in 1979 and earlier like the 350, 351W, 351C, 429, 460, 405 are virtually interchangable with a vehicle except for the cooling system inlets outlets,exhaust manifolds,and air breather..

What type of ventilation system is required on inboard gasoline engines built after 1980?

Inboard gasoline engines built after 1980 require a ventilation system that includes both a natural and mechanical ventilation component. This system must ensure that any flammable vapors are effectively expelled from the engine compartment to prevent the risk of explosion or fire. Additionally, it should comply with the standards set by the American Boat and Yacht Council (ABYC) and the U.S. Coast Guard regulations, which mandate proper air exchange rates and exhaust fan operation. Regular maintenance is also essential to ensure the system remains effective.


What kind of ventalation system does an Inboard gasoline boats built after July 31st 1980 need?

Inboard gasoline boats built after July 31, 1980, require a ventilation system that includes both natural and mechanical ventilation to prevent the accumulation of explosive vapors. The system must have at least two air inlets and one outlet, ensuring proper air circulation within the engine compartment. Additionally, the mechanical ventilation must operate automatically when the engine is running and should be capable of exchanging the air in the compartment at least once every three minutes. This is crucial for enhancing safety and compliance with U.S. Coast Guard regulations.


Do all newly made boats have an outboard motor?

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.
