Hello all,
First, pardon my english. Its my second language.
Hope someone can help me troubleshooting. Engine is Mercury 70, 2 stroke, 3 cyl. Not sure of year. Think it is 1980. Engine serial is 9353083.
Problem: Just bought boat+engine. Engine worked flowless a couple og days then suddenly died. Now it wont start and also there is a problem with cranking motor not always starts.
Engine not starting:
All 3 spark plug has spark. I suspect problem with fuel/fuel pump. Disconnected fuel outlet from fuel pump. When cranking engine very little fuel came out. No pressure at all.
Problem with cranking motor:
One bolt/screw on starter solenoid is loose. I guess this is a failure?
Included is link to picture (380kb) of engine with starter solenoid and what I THINK is the fuel pump. I dont know why there is so many connections to fuel pump (see picture). I guess I have to remove fuel pump and open it?
Also, I did find my starter solenoid here at MarineEngine, but I am not allowed order any parts since I am in Europe. I find this very strange. Anyone know where I can order parts online where shipping to europe is not a problem?

Not quite clear on the problems, but you have the fuel pump correct. I would open it up and inspect the rubber membrane inside for cracks/rips etc...
The hoses use pressure form the motor to move the diaphragm back and forth to pump the fuel. Modern fuels have alcohol and this attacks the membrane.
Starter solenoid is no big deal - but is the engine not turning over intermittently? Then yes solenoid is likely the cause... otherwise you are looking at carburators / ignition etc... |
