50 mercury hp no start

[phatdaddy]

6 gallon tank or built in tank?

Quick disconnects on fuel line?

Go buy a qt of Trufuel 50:1 E free fuel.
Disconnect fuel hose from tank.
Stick it in the Trufuel can
Pump ball till firm
Start motor

If it doesn t start, problem is upstream. . . Fuel pump then carbs
If it does start, problem is downstream. . . Filter,tank pick up,connection.

Also, i know u run ethanol, so could be collapsed lining in fuel line

If it does start on the Trufuel then dies, try holding the can higher than the engine. This will give u a flooded suction to the fuel pump and make it easier for a weak pump to pump fuel. I used to be able to tell when my fuel pump was getting weak on my old Merc because after trolling about 15 minutes, it would get slower and slower. Would have to go back and pump ball.
