So my 2015 Yamaha 150h speed doesn't register anymore. About 3 wk ago it was half of my GPS Speed. I looked it up, you tubed it, and ran a wire pipe cleaner brush into it for a little ways just in case there was mud or a dirt dobber in it. Got any quick fixes before I run it over to my mechanic. The rest of the instruments on the panel run fine . Figured it was some LA mud still in there from getting in skinny water looking for reds with SCN back in the early spring
