Hello,
I have a TB350 XLI. Everything appears to function. Fuel pump turn on, motor turns over. I thought that maybe the coil was bad.
I swapped the coil with the starboard engine and the motor fired up okay. So i think the coil is good.
I checked the coil wire input to the distributor cap with a screw driver to the cap no spark. I think the fuel pump is providing fuel to the throttle body.
I checked the distributor the cap and rotor looked old. I changed the cap and rotor and the distributor ignition input module.
Still no spark. I'm thinking there must be something going to ground. Does anybody have any ideas?
Thanks for your time.
 
I doubt "something going to ground"...

On the ECU controlled EST ignitions, a no-start after swapping the ignition module is most likely the pickup coil failing...did you do the resistance test on the pickup coil when you had the distributor apart?

Thanks for the reply. I did not measure the
Distributor. So the 2 conductor female cable that the module connects to on the distributor is the coil your talking about?

I didn't measure yet. I'm headed that way tomorrow the boats kept 2 hours away. I'll check that right away when I get there.
Thanks Again
 
the pickup coil is two conductors - it connects to the module opposite from where 4 conductor cable going to the ECU plugs in...

Hello,
I wanted to let you know. I replaced the distributor coil and the motor fired right up. Sorry
for the delay. The coil cost $20. Thanks for your help.
Happy 4th of July!
 
I did change the internal distributor coil. Measured open with the meter. I still have work to do.
I hit a log last fall. Bent a strut and propeller. I'm not sure if the shaft got bent. I opted to put the boat back in the water
last season. I putted back to the slip. I didn't want to end having to pay for a slip as well as pay for shore
storage too. Now that I have the motors working I'll go ahead and pull the boat. I think the strut
can be tweaked back to normal since the bronze is a soft metal. However not sure how to check to see if
the shaft got bent. Any Ideas? I was going to pull the prop and put the motor in gear at idle. The shore service should have
some ideas. I made it 30 years without hitting anything substantial.
Thanks,
John R
 
The best way to check the shaft is to pull it and have a prop shop measure it. Since you are gonna get it hauled, you could get a solid support under it and use a dial indicator..

Best not to have the engine spin the shaft when the cutlass bearing is dry...

You may get a rough check just spinning it by hand...
