Last year my wife and I got two sea doo PWC. I need to re cover her seat. I am not sure if hers is a GTI SE 130!or 170. I guess this makes a difference. I do have the HIN but I am stuck at this point. Can anyone tell me how to find out if I have a 130 or 170? I cannot find a free HIN sit to look it up. Does Sea Doo have a site? Thank you in advance.
