Hey Guys!
In desperate need for some help. My boat recently took on some water, one of my friends left the plug out when launching and took me a few minutes to realise what had happen. I soon jumped in the water to fix the problem.
I’ve completed multiple flushes on the engine so hopefully I haven’t caused any major damage.
We had the boat in operation for about 3 hours after this then suddenly it wouldn’t start.
The engines not getting a spark anymore. From what I could see nothing got wet that should be causing this problem. Perhaps just a coincidence that this problem happen at the same time as the water.
I’ve checked for power and that’s all fine. I replaced the components on the dizzy in case that was failing but still nothing. From what I could tell the ignition coil was working fine. When testing the power running to it I could only find 11.2 Volts. I thought this may be the problem
I tried to run straight 12 volts from the battery to the coil and blew the thing up. Fingers crossed a replacement coil will fix the whole problem but just wanted to check and see if anyone else had any thoughts. Thanks heaps

Literally the coil blew up or something else?
Don't think the water caused anything currently seeing since nothing got wet

Have EST distributor, TBI using VST tank
Check the dizzy and fuses on the motor
