Re: repair manual for a 2009 mercury 30 hp 4 stroke
I bought mine online for $20, "Seloc"
Covers my Merc 2-stroke and all 2.5-275 2 strokes from 1900 to 2000
I also bought one to cover my other 2 Merc 4 stokes.
For $19.95 they pay for themselves because if you break a part removing it incorrectly, it will cost a lot more than the manual to replace it!
West Marine might also carry them if you need one quickly and are near a local store, but they will get the list price which is probably $37.
