Blowing oil at start up

[Getting_started]

Friend has an older Yamaha 50 2 stroke motor that just started throwing oil on startup. The motor starts no problem, but it looks like the lower end is throwing out globules of contaiminated oil. It's not coming from the cooling water. It is being ejected under the water. Lots of brownish globs of oil. The motor is obviously in neutral when started so I'm not sure why startup would cause this.

It generally only happens the first time it starts and doesn't continue if you idle around in gear.
