Wear ring ? ?

[tx95xp]

I have a 97 gtx thinking about buying ,the problem is it has a hard time plaining out (getting on top of water) low end power is good and top end seems good (50 mhp ) by speedo .... It's like it starts sucking air . This is the 787 or i guess it's called 800 .. Thanks in advance !

check wear ring, impeller and intake grate 1st,

Check engine internal health by compression reading = 150 good.
99% of rpm failure is fuel system related. Other is no maintenance!
