I have an EvinRude 70HP Model #E70TCLEM and serial G02264688.  This outboard has ran fine since spring.  I always hookup the hose mufflers and fire the engine before leaving for a trip.  This time, the engine fired and ran for about 1 minute.  I pressed in the key to prime the pump and it started again and ran for 1 minut.  It has not ran since.  The engine turns over fine but will not start.  I checked the carbs for water by loosening the screw at the bottom but nothing came out.  Also, can someone tell me what year model the engine is?
