Last fall when I got my SC winterized they put on the bill that the computer on my sea doo had 10.5 hours. I just de-winterized it and the hour meter states that I have 25.7 hours. Is it common for this or is it something that I should take in and have them look at? It is hard for me to think that the 25.7 is correct. I know I rode it a lot but just getting it on July 4 and winteize it in Oct with only weekends its hard to believe. thanks for your help, Mark
