I am the fng here and I need some help. I just bought 2 1989 skis (wave runner and jammer) on a trailer for $300 the runner runs good but the jammeer has problems does any one know where I can get an free service manual? The prices on the ones I have seen on line are well and I refuse to pay that much I have hered that they are availble in PDF format does any one have one they could e-mail? I would be very greatful!
