I am new to the jet ski world and I have a couple questions. I recently purchased a 98 zxi 1100 and went riding with my son, he has a 99 ultra 150. and I couldn't keep up with him, I realize his has a bigger motor but I thought I'd be able to at least ride with him. Just wondering how fast I should expect my 1100 to go. It was running over 7000 rpm and sounded great just seemed like it should have a little more power. My speedo was a little intermittent but I would guess my top speed was around 50 and my son was running about 65 on rough water. Any suggestions where my power loss might be would be great. Also, I was going to do a compression check and wondering about what I should hope to see there. THANKS
