1997 Evinrude 175 carb motor. Starts good and runs good. No VRO, been mixing my gas the last 10 years. Lately been noticing the color sheen on the water at start up and whenever I stop to fish. Sheen continues a long time. Pulled cowl and air box at home. Most everything behind air box is wet with fuel. Having someone squeezing primer bulb (not running) and searching for fuel leaks. See nothing moving. Start motor and look again. Nothing visibly flowing. Fuel pump, carbs, fuel rail piping, filter etc. No liquid moving But.........everything around the carbs is wet. All 6 carb bowls are wet around the bowl gasket area. No weeping from the "ball bearing" areas.
Inside I wet enough that I have a few drip of mix dripping from upper rear port down onto lower unit.
Guess all six need new bowls and gaskets?
