    rpm's o.k., lost top end

    At the end of last season, I let my nephews ride my '98 XPL. Before they took it out, it turned 6800 rpm, and would hit 62-63mph. When I took it to the ramp, it still turned 6800 rpm; but, top end was about 52mph. A check underneath shows nothing blocking the intake, and the impeller looks good. Thoughts (other than keep the nephews off it)?
