    Exclamation Somebody help me out diagnosing my problem

    I recently bought my first ski, a 2001 GP1200R, and for the first few rides, the thing would jump out of the water from a standstill when I give it full throttle, now recently I took it out and when I go to give it full throttle from a standstill, I wont get max rpm's ,it will start in a way plowing through the water, and at about 13-15mph it will get on plane and do 63 mph no problem, I checked my intake grate and impeller and everything is fine, I cant seem to figure out the problem. I run 89 octane in it, the previous owner ran the same thing, he is also a well known mechanic in my town for jetski's. Before I take it to him, I woud like to have a few possibilities I can tell him.

    You want to check your prop liner. You have to take the pump area apart. Also make sure there is no corrosion on the mating surface of your liner and transom plate. When you put it back together use some RTV sealant.

    Well one of the firefighters at my station used to have a ski, i explained ot him what is going on and he said soemthing about a thing that surrounds the impeller, kinda a plastic material and he said sometime is wears and pieces of it will break off and no a much water gets compressed. So idk.
