2002 Yamaha oil pump??

[hendu3270]

Hey guys, I have a 2002 15 hp 4-stroke. My oil light is "On" and my oil level is fine. I know I should probably know more about my motor, but I haven't had it that long and I'm still learning.

Does this little motor have an oil pump in that can go bad? or is there typically an oil filter that might need replacing?

Thanks,

Chris
