hi i have a 1981 bayliner force with the 3.0l (engine block casting # 2770087) 140 mercruiser. it had a cracked block . is here a non marine block that can be installed, i have hear that the engine is an iron duke. if so is block the same as the non marine block? are they really the same engine and what would i look for?
