New Boat/ Boater...

[misteright1_99]

I purchased a "used" Glastron with VP I/O 3.0 with SX drive. I started it up this week, with the muffs and brought it up to operating temp. and noticed not much water coming out the prop, but out from under the sterndrive. Is this an exhaust bellows leak? I cant see up behind there to see if exhaust bellows is torn. Is this a do it yourself repair? Where can I get a repair manual for newer VP? All the manuals I see are only up to 2000. This boat has 16 hours on it.
Any help would be appreciated
