I went fishing with a buddy and we almost didn't make it out because his engine wouldn't crank.
After many many spin overs it finally fired and off we went. Rest of the day it fired immediately.
He said its been doing that lately. Ball pumped tight. Thinking fuel pump maybe? Lossing prime.
Any thoughts are appreciated. I just wanted to help him out if I could.
I'm sorry I don't have a ser no. but its 1990 Mercury 70 hp.
