Hi all.
I have a 1994 120hp outboard and whilst out last weekend for a slow trip up the river with the family, we came across a spot of trouble.
Going out, I decided I wanted to use a plastic fuel can (25 litres) to check our economy so I filled it with fresh fuel and oil, put the boat in the water, it started fine, ran well at all speeds, then we entered the river and ran it for about 30 - 40 minutes at about 2500-3000 revs (speed limit in the river is 10Kts).
Ran out of fuel in the reserve tank, no problem, switch to the main tank, prime up the bulb, start the motor again, off we go again.
Not that easy. The engine wouldn't start. Tried and tried and tried again, no good. Good thing we were in the river and within drifting distance of a pretty big and pretty expensive private marina.
Got over to a berth and checked: Plugs (looked fine), fuel (cracked the fuel line off from between the 2 carbs and petrol sprayed all over the place), spark (looked really weak but it was there, at least I think it was), checked spark again and nope, No spark.
Looked around everywhere, coils, plug leads, CDI. Tried starting several more time using a jump pack and even a completely new battery. Actually did get it started, after about 2 or 3 hours, don't know how, but it stalled the moment I put the throttle in gear. Where do we go from here? I've tried cranking it at home with the muffs on and and after a couple of 15 or 20 second attempts, it actually fires but it won't start.
Going to try pull the flywheel off in the morning to check the magnets underneath it and the stator. What should I be looking for at the coils and the CDI?
