Finally got the new Rochester quadrajet on there, this time I ordered the part so no Napa auto special from last mechanic. Check out this original 1981 fuel pump! It weighs more than twice as the new replacement. We pumped out the old gas. Marina that winterized her used ethanol gas dammit. Pumped out 20 gallons replaced w 91 non ethanol. Boat started right up, idled perfectly, got up to 45mph at wot w aluminum prop, two adults w half a tank.
