Hi, have got an 07 Hurricane with a Faria tach and a 115 4 stroke Yamaha. It's got 83 hours on it total and about 10 hours ago the tach started reading about 1500 rpm high. Boat runs exactly the same as far as speeds, engine noise and smoothness. I even swapped props just to make sure it wasn't slippage. Does this seem to be only a tach problem or can something else cause this?? thx
