Good afternoon - I'm new to the group and to Outboard motors. I have a 2002 Mercury 150XL that is running poorly at idle. It starts great cold and often stalls until reaching operating temperature. It's hard to start when warm or sits for a while. I'd like to change the Spark Plugs and the Fuel line/ fuel bulb and unfortunately I'm not in close proximity to the boat. Can anyone point me in the direction to find OEM part numbers by Serial Number?? Does anyone know what spark plugs I need to purchase?? Also what Fuel line / Fuel Bulb i need to order??? Thanks in Advance
