Launched latest purchase today (1995 Maxum 2300sr, 1995 Mercruiser 5.7 carb with Alpha 1-II. Hasn't been run in two years and ran fine during initial trial and then noticed a fuel smell after 15 minutes, opened engine cover and saw small amount of fuel in bilge. Shut down totally and quickly towed back to shore. It has an aluminum 63 gal tank, all the fittings appear to NOT be leaking (tank, pump, carb, filter). After sopping up the fuel (less than pint) and ventilating I started again with no apparent leak. My question is: with original mechanical fuel pump, could the fuel pump gasket have been dry, leaked under power and needed to swell??? If so I'll obviously replace pump.....but am I missing something?
