Call jim the mobile merc man he can tell me whats wrong with my 99 model 175 over the phone 90% of the time and with the half dozen problems i've had hes never been anything but 100% right. I don't have my cell on me or I'd get it for you. PM me if you need it or someone can send it to you. He doesn't charge for phone consultation and will almost always tell you what you can do to fix it.
