Invention relates to a powertrain (2) in-situ conversion of a marine vessel (1) which is provided with at least one propulsion powertrain, configured to provide thrust to operate the vessel (1) at a predefined first operating profile, such as design speed, and the at least one powertrain (2) comprising a multi-cylinder two-stroke internal combustion piston engine (6), a propeller (10) and shaft arrangement mechanically connecting the propeller (10) and the engine (6), the conversion comprising configuring the powertrain (2) to provide thrust to operate the vessel (1) at a second operating profile with less power demand than the first operating profile, wherein, - existing combustion chamber components (200) comprising at least a cylinder sleeve (114), cylinder cover (116), piston (112) and piston rod (110) are removed from the engine (6) of the at least one powertrain (2), and - new combustion chamber components (200') are assembled to the engine (6) of the at least one powertrain (2), which new combustion chamber components, including new cylinder sleeve (114') having smaller bore diameter than the existing cylinder sleeve (114), are configured to produce higher specific power than the removed old combustion chamber components (200).
