Neutral safety switch have anything to do with that ?

yep....i bet thats it !

I don't think so, that just cuts power to the starter or at least as far as I know!

Hmmm..this is interesting. Especially that it happened to both motors. Please let us know what you find sir.

No problem Mike, I know how it goes and been there and will be again. Just the way it goes sometimes. Were on the right track and will have you on the water in no time. Just glad we did the process of elimination. New boat - new set of issues. Also was nice after we fired engine number 2 that it stalled out when it did. Don't think it's any faulty equip or parts. Just fixing what somebody probably had intentions of going back to at some point however didn't get around to it. lol... He could be chuckling in his grave while we scratched our heads earlier.

The question I have is how the safety tether actually works. I thought it would simply cut the voltage off to the coil however after this evening I believe it works in conjuntion with the TB module. See ya in the morning. At least you'll sleep a little better.
