Took my 1997 SN GT-40 out to the lake yesterday. Boat started and ran great initially. While pulling my daughter boat shuts down abruptly. It was like I pulled the lanyard to the kill switch. The switch did not get pulled but I still thought it had to be a problem because I cycled the kill switch a couple of times and tried to start the boat and it fired back up. This happened a couple of times while on the lake and boat ran fine when running. I wasn’t to worried about it because I thought if it ever shut down and I couldn’t jiggle the kill switch I would just bypass the switch while on the lake and fix it when I got the boat home. Well I got the opportunity to bypass the switch and this was/is not the problem. Motor/starter turns over but boat doesn’t run. I did get it to run after about an hour trying to get it to run and made my way to the boat ramp as quick as I could. With the boat finally on the trailer I shut the boat down and tried to re-start. It did not start. Any ideas on where to start troubleshooting would be appreciated. Thanks in advance for your comments. I have searched the website but could not find anything quiet like my problem.

I'd be maybe thinking relays.

So the starter will always crank, right?

Also, how did you bypass the lanyard, keep in mind that controls the fuel not the starter.

Yes starter will always crank. I bypassed the laynyard by connecting the two wires attached to it. This is correct right?

update: I decided to drain the FCC just to see if trash/water was in the bowl. I removed the bowl plug and gas started to flow out of the drain like it should. Shouldnt the gas stop flowing out of the drain? I filled up 3.5quarts of gas and it was still flowing. Does this make sense? Probably a dumb question but I dont know.

And it started at least once with the lanyard bypassed, right?

I'm just asking cause I don't know if that circuit being opened or closed triggers the shutoff.

Not sure on the draining of the FCC, maybe the low pressure pump was still feeding it?

Either way, your problem sounds exactly like Keith's bit about the TFI, here. Maybe 97 was a bad vintage for TFIs as Keith's is also a 97:

Scroll down about halfway to get to the TFI stuff.
