Hello everyone,

I am a begginer with boats but have some experiance with cars...

Just bought a '96 bayliner ciera with a Mercruiser 5.7 litter 2 barrel
carb Thunderbolt 5 Ignition
The thing ran fine for a while, then wouldnt start when hot and
eventually now doesnt start at all.

It cranks, turns over but no signs of life. I am getting gas for sure,
can see it in the carb.
I already changed the spark plugs, wires, cap, rotor. No change.
There is voltage going to the coil and continuity throught the coil.

There is spark comming from the main ignition wire (visible if you
touch ground)
There is also spark comming off the ignition wires (when you touch
ground)

When it did run, it ran just fine and I didnt't touch anything, so I
doubt it's the timing..

SO I get gas, I get spark and nothing.... I am aware of the ignition
module/sensor and some kind of a changable ignition pick up sensor in
the distributor, but I have no idea how they work and wether they are
the problem. Me and my buddies are totally stuck. Anyone have any
ideas?

Any help would be greatly appreciate it....

Thank you,

Alex.

Spark should jump a 1/2 inch gap to ground from a spark plug wire. Often hot
no starts are due to a bad coil or sensor module in the distributor. Also
gas could be percolating out the carburetor flooding the engine when hot. Or
you might have a stuck float. Check the choke operation. There is a
possibility that the plug wires aren't on right. Squirt a little carb
cleaner into the carb then try to start.
Trying to fix this problem over the internet could be a lengthy process.
Your best bet is to get a pro to look at it for you. It shouldn't cost much.


Good advice. I should have read your post before pounding on my keyboard!
