Reply To: 1969 Evinrude 40 won’t start hot

Have you checked for spark when the engine is hot and won’t start? You mention something about the engine starting fine if the cowling door is left open…If this is true, then you probably have and exhaust leak causing the engine to breath its own exhaust. There is a big donut type gasket that surrounds the inner exhaust housing that could be damaged or out of place. You had the gearcase off, so that means you had the rear lower cowling off…Did you see the big donut gasket then, maybe it came out of place…
