The other day I took my brother-n-law's boat to the lake. I got out to the middle and started fishing. When I tried to go to another location, it would not crank up. It is a 45hp Mercury Classic Fifty, not sure of the year 90s I think. No matter what I tried it would not work. I tried to start it w/ and w/o the throttle engaged, choke/no choke, made sure it had sparks on all 4 plugs, bled the gas line and then primed it to make sure it was getting gas, let it sit for a while to make sure I hadn't flooded it, spray gas mixture in it and then starter fluid but still nothing. What am I doing wrong?
I ran fine at home with hose water running through it and it ran ok getting us out to our first stop. It has a brand new deep cycle battery. Now it did never plane out, but I don't know what that may mean in relation to the problem. ANY SUGGESTIONS ARE APPRECIATED.
