[looking]

Ok so I just bought this 04 SeaDoo and it had 34 hours on it. The guy I bought it from said he had the 10hour maint. done on it but had not done anything else. The service shop I had it taken to said the oil level looked good but I was wondering about the viscosity of the oil being possibly 2-3 years old. I was thinking about going and having the 100h/1yr maintenance done. Any suggestions?

Thanks
Frank
