I need some help. I have been trying to fix our ski boat with no luck
ITs a sanger v-drive with the 315 scorpion engine 1997 850hrs
the engine dies after running for a while(approx 10-20min) it runs perfect till this happens. you can feel it start to cough or miss and can definatley
see it in the tach(fluctuates) then the engine flat shuts off.
I thought it was fuel, so I replaced the fuel pump. started and ran fine and went for a test ride. 4800 rpms no problem then same chiot. Tach flutered and shut off.
So this weekend I replaced the distributer module. same thing, this time it ran for 30min then shut off.
note: the engine will refire after sitting for a little while and run perfect, then wamo=dead
I have not put a DDT on it, I will try to aquire one.
any thoughts would be greatly appreciated.
Its the wife's boat and its been down 4 weeks. She already said if it was my boat it would have already been fixed. (she's right but wtf)

You didn't mention replacing the water separator filter.
-
floats may be sticking shut. when it dies, have you tried looking to see if fuel is coming through the carb? sounds like a fuel issue.
-
fuel filter, clogged fuel vent, sediment in gas tank are other possibilities to check
-
With that engine being EFI you really need to get it on a scan tool to find out whats going on. It could be something really crazy like a sensor. I have the HP-377 Scorpion in my Eliminator and its a killer engine. Mine is 370 horsepower!
-
ok, had no idea it was EFI. dont i feel stupid now. :cry:
-
Could it be the coil getting hot?
-
When it dies cool the coil down with water or ice and see if it restarts.
-
Yep other than running a scan I am thinking coil. I have seen this happen exactly as you discribe many time. Let us know what you find out. Have you check for spark after it dies?
-
I had a bad coil and it acted the same way you are describing it.
