A boat propulsion system, OSD-Outboard Stern Drive where single, or multiple marine engines are positioned at boat stern inside boat outer envelope on customized-elevated subfloor and connected to outdrive unit that is attached to boat stern plate. Engine/s are positioned lower than typical outboard engine/s and higher than typical inboard engine/s. Engine compartment is covered by a customized hood and engines are easily accessible from boat floor like typical outboard engine configuration. Drive configuration is like typical sterndrive with engine/s crankshaft in horizontal position that is connected to outdrive unit via cardan joint allowing drive tilting up and down. The main purpose of using OSD would be use of one or two Diesel or gasoline marine engines of existing design thus eliminating use of 2-6 large outboards for boats longer than 25 feet and outboard like access to engines for maintenance while using sturdier marine engines and providing much simpler boat/engine configuration.
