[91superjet]

My 91 superjet starts and runs fine out of water but when i try to ride it, there is no power too it, i can go about 5mph. Any suggestions on what I should check on? Thanks.

so it does not rev up in water

check compression

Compresion

I tested the compression and it didn't look promising. one topped out at about 115 pounds and the other at about 90 pounds. I guess this means I blew a ring? if so, is it a project better done by a professional?

you can do it
