Put 30 gal of gas in my 2009 190 CX and my gas guage reads just over 3/4 full. When I got to the lake there was gas all down the side of the boat and even on the trailer fenders.
Changed the seal in the gas cap to an o-ring and that only slowed down the overflow. Last year I had no such problem, but I never filled the 50 gal tank over 1/2.
Anyone got any suggestions, since my dealer is no more.
