65 hsp Mecury with thunderbolt ignition

[speedingway2fast]

Last summer my motor was submerged. Now when I try to use the boat it will run fine for about 10-15 min and just dies out . You let it sit for a little bit and it will start and run for a little while again. the only mechanical change I have made would be a suction pump ball in my fuel line. Any ideas anyone?

I have the same motor, you said you changed the bulb. Make sure the arrows on the bulb are both pointing to the motor, not the tank. And you have air valve open on the tank.

Speedie, I think you need to check your spark when the motor dies. I suspect when your electronics get hot, they cause a no spark condition. If you find you have no spark, you will need to isolate it to a particular component.
