My '77 Evinrude 70 hp starts fine, runs for a while, then slowly dies and immediately can be started again. Plugs cleaned, new steer box, new gas filter, new gas tank. What's the problem?!

Welcome to iboats, Louise. Check the tank vent by cracking open the filler cap,to allow air in the tank.<br />Evinrudes of that vintage had problems with coils, but the engine would've started to miss real bad, if this was the case.<br /><br />Look for a loose or corroded connection around the switchbox,stator and trigger. If in doubt,clean it shiny. It could be an intermittant contact.
