I recently bought a 1978 75HP Evinrude for $100 bucks. Person said it didn't run. I cleaned out the mice nests and cleaned the gunk out of the carbs and luckily she fired right up. Runs like a champ. However I'm not sure if the water pump is working correctly. I don't know where the water discharge is at on an Evinrude. I've only owned Mercury's and they come out of the pee hole on the top. So my question is with my muffs hooked up where does the discharge water come out on an Evinrude?
