Help!!! I own a 1996 Kawasaki 1100 zxi. I put it in water this year and it started fine and the engine appears to be running fine up to 6500 rpm but it only goes about 20mph in the water. I pulled it out of water and check the impellor and checked the intake and all appeared to be ok. I did not check to see if the impellor was tight or not but it looked ok. Anyone have any Ideas??????
