    I have a 1971 Chrysler Sport Crown with a B30 AQ170A/270. Is there an updated/newer engine and outdrive that I could swap this engine out for without changing the current transom cutout? Or replacing the transom?

    Any suggestions or recommendations are greatly appreciated.

    Thank you,

    you could update to a volvo 3.0lt without cutting transom. you can also fit a mercruiser with a 270/280 to mercruiser adaptor plate without cutting the transom.
