Super Jet superjet problem?

So my new to me 01 superjet starting having issues 2 days ago. History behind it since I bought it. Ran 2 tanks threw it and ran fine. Friday went out and ran fine for the first 10 min. Then started to sputter at top end. Kept getting worse the more I rode it. Put it on the trailer and it revved up fine. Brought it home and planned on working on it Monday. Pulled it of the trailer and a few hours later noticed it was leaking water from the front intake grate bolts. Did a little inspecting thinking it may be coming from where the drive shaft goes into the hull. Didn't feel any water higher then where the grate sits. So my question is could it be the mid shaft bearing that is causing the machine to not rev up and feel like the pump is falling off? And is it even possible for the hull to leak from the front intake grate bolts(just doesn't seem possible)?
