I have a 60 hp Mercury outboard 2000.( bought new) this problem has been there since almost brand new. The motor starts up fine after a good pumping of the primer bulb and a choke. The problem is that when I go out fishing, throughout the day, I'll shut it down to fish then when I try to start it up again it's a real chore to start up. This dosent happen everytime, but about half the time. Sometimes it will pop right off. I have to remove the fuel line and crank it over till it starts, then hook the fuel line back up. Its what seems to work the best.
