Hello all, new to the forums, been searching through the forums trying to find an answer and not coming up with much. I have an 86 3cyl. 50 that I just got. it was barely running and pouring fuel out the exhaust after fixing the fuel pump and the carbs it runs beautifully for the few seconds it's been run but it wont push any water out the telltale I pulled the hose off the outlet at the top of the motor and still got no water,I ran it for 20-30 seconds max. I also blew into the hole with an airgun and got air out of the exhaust so I believe it's not obstructed.I don't believe the 86 should have a t-stat and I was told that the water pump was new. before I start learning how to pull the lower unit apart and replace the water pump am I missing anything?
