Re: 77 75hp evinrude
Hi Skecher,<br /> First, check for spark and compression. You'll want compression in each hole to be on the far side of 130psi and within 5% of each other.<br /> If those check out, move on to the fuel system - carbs will probably need rebuilding - not as bad as it sounds. An aftermarket manual will probably work for this (Clymer, Seloc, etc.)<br /> Move on down to the water pump impeller - install a new one regardless of how "good" the old one looks.<br /> Give her a tank with fresh gas mixed at 50:1 with good TCW-3 oil, plus a good battery and a set of ear-muffs hooked up to the garden hose, then give her a whirl!<br />- Scott
