Drive shaft grease leak

[jbbassn]

I have grease coming out of the top of the drive shaft where it goes up into bottom of cowling. I recently added grease and was wondering if I popped a seal. It's right above a zerk fitting. Hoping it isn't a problem and doesn't need fixed. Also I normally run 5400-5600 rpms. I hit 6000 yesterday on a Mercury 150 efi. 1997 model. Is that too high?sea
