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?
