trying to get the serial # from my motor

[Wpg Manitoba]

I'm putting my boat for sale and I'm not sure what the serial # is. It's a 2002 2 stroke 25hp tiller. I have this letters and numbers and want to know if all of them are part of the serial #. It starts like this 6L2K S followed by 6 numbers. Is all of that the serial number or just the 6 numbers that follow at the end?

Yes all of it including the prefix is the serial number.
