A marine outboard motor (2, Fig 3) is provided with an internal combustion engine 100 comprising an engine block 110 having an engine lubrication fluid circuit 180, at least one turbocharger 160 having at least one lubricating fluid inlet 192 and at least one lubricating fluid outlet 193, and a turbocharger lubrication system 190 configured to lubricate the at least one turbocharger. The turbocharger lubrication system includes a feed path 191 extending from the engine lubrication fluid circuit to the at least one lubricating fluid inlet, and a drain path 194 extending from the at least one lubricating fluid outlet to the engine block. The drain path includes at least one drain tank 195 configured to receive lubricating fluid drained from the at least one lubricating fluid outlet, and a scavenge pump 196 configured to return lubricating fluid from the at least one drain tank back to the engine lubrication fluid circuit.
