Mercury 20 EFI FourStroke

• The port side lower cowl has two bumpers to help reduce damage to the cowl when the engine is stored in the laying down
position. Storing the engine on the port side will prevent oil from draining out of the crankcase into the cylinders or
crankcase ventilation system. There are bumpers on the aft side of the top cowl also.
