Hello,
I have a Yamaha-built Mariner 2cyl 2stroke man-start outboard that broke down at the lake the other day. After shutting it down for a few mins, it would not restart. After checking the tank, line, bulb etc and attempting to start several times, I realized the bulb would not stay firm...
Serial number is 689 L 525571. Doesn't seem to fit into the serial number ranges on any sites I've looked at. Maybe between 1986 and 1989? Any help would be greatly appreciated... Thanks
