I just bought a new (to me) boat, and on her maiden voyage she was running fine. After about 45 minutes, I was pulling a wakeboarder, and she just died. I tried to star her again, and she would turn over, but wouldn't fire.
Things I have checked:
1. There is no kill switch. There may have been one in the past, but it has ben rewired, and he may have bypassed it. I have yet to eliminate this as a potential problem.
2. Fuel system is fine. I thought it would be the culprit, but I ran an AUX tank with a direct line, and also squirted a little into the carbs...no firing.
3. Had a buddy help me test some of the electrical. The coil is transferring power (not sure if it is the right voltage, but the coil looks brand new???) to the distributor. When I checked the distributor, I am not getting spark. When we hooked up the multimeter to one of the cable terminals on the distributor (with the coil attached) the needle did not even move.
- When I popped the cap (which looked new as well) there was one (of 4)screw that was broken, and it looked like a bit of corrosion on a sensor (Hall effect sensor? the slotted metal cap under the rotor rotates through a gap in the sensor)
- I am not sure what the sensor does (or if that is the right name?), but is it possible that it would limit spark to the plugs if that sensor has failed?
Other Helpful ino:
-I was told it is a merc 5.0l 1992 rebuilt engine. I am not sure of the serial number, and I am not at the cabin to check.
- Both batteries are brand new, and have a good charge.
- I took off the oil cap to crank it over, so I think the timing chain is good. (i read on another post to check that, but I may have just sounded like an idiot)
- As mentioned it has been rewired, and it looks like a bit of a rat's nest! It is possible that a wire has popped loose, (given the symptom of it just stalling out) but if the coil is getting power, wouldn't that mean that the wiring is good up to that point?
Thanks in advance for any help. Please keep it in fairly simple terms, I don't know a lot about motors, but I have learned a ton in the past few days, and am willing to learn more...I can google the terms I don't know
I can't afford to take her to a mechanic right now...I just spent all my money on a boat!!
