I have a 1998 Playcraft Sport pontoon boat with the original 60HP 1998 Mercury motor on it...but I don't have the model number or serial number of the motor. Can anyone tell me what spark plugs I need and how many? The boat is at the lake and I was hoping to pick up the plugs before I got down there but can't figure out what motor it is...even though I know it's the original motor. Thanks for you help!!!
