    Ok, I went to my local Sea doo dealer and the service tech told me I would not see over 8000 rpms because my gauge redlines at 8000 RPMs. He said the digital display will not show more than 8000 RPMs...

    Well, I went out for my 90% throttle breakin period. I hit 8000 rpms briefly and easily but it would not go over that. Felt like I was at 3/4th throttle 8000 rpms, no where near WOT. I bagged off the...

    I had a leak here too and had to change the valve.

    I'm on the water breaking into engine now. After my first hour air fuel ratios we're hovering in the low twelves at idle. But since I couldn't go over 4,000 RPMs I got kind of skeptical because my...

    Well I do think I have a bendex problem but while I was going to sleep last night I figured my ski never took two cranks to start. So I knew there must have been too much gas. I have my fuel pressure...
