Hi guys. My names David, hope everyone is well!
I have a evinrude etec 115hp 2008 E115dpxscr
I have taken my boat out 4 times with same results. Drive a few kilometres and then Boat shuts off. Once this happens I cannot start it up again untill a few hours later and then it will start and go for a few kilometres again. At home with hose I can leave on for hours and it’s fine. Doesn’t shut off. Any ideas

Hi,
Some more specific info would help but IMO from what you described it would seem to be the water pump needs servicing / replacing. If the impeller is worn it will still supply enough (cooling) water to cool the engine when idling but not enough when running on the plane.
Idle temp is around 160 F and running on the plane about 120 F WHEN the water pump is in good working order.
Get a History Report via Evinrude Diagnostics and post on here (via a third party hosting site) so the experts, not me, can give you specific advice.
Cheers
GEB

++ to GEB!  Those "over temps" will show up in the report, but the HP fuel pump or ignition coils getting hot and quitting most likely won't.  Once they cool down, they're good again until they heat up.

EDIT:  As always, fuel delivery scares me.  If your fuel tank, etc. develops vacuum, you're running Lean, which can cause serious problems.  The waiting may be allowing air to get back into the fuel tank through the vent.  Try cracking the fuel cap open maybe 1/2 or 3/4 turn, and see what that does?  If it's still the same, don't keep trying until you've found the real problem.

Thanks guys. The motor still has a steady stream of water coming out the back and doesn’t show any codes of overheating although it is showing SAC Overcurrent. Code 77.
GEB.
The boat starts fine and runs fine for a few kilometres on the water and it just shuts down almost instantly wheather in high speed or low. It drives a perfect speed it doesn’t struggle or anything but after a few kilometres of driving it’s shuts off and I cannot start it again it. The next day at home It will start after a while and then seems fine

Code 77 shows this for my old I-3 motor - "Check for shorted 55 V wiring (injector circuits). Check for pinched or chaffed wiring."

Not sure why it would run fine and then die after warming/heating up.  See above suggestion.  Could also be the HP fuel pump or injectors quitting when getting a bit warm?

10 year old motor, do basic tests first.
Compression tests cold and hot.
Ignition spark tests cold and hot with inductive timing light.
Motor fuel pressure tests and boat fuel system vacuum/air bubble leak tests.

Please post up the latest copy of the Engine Report by uploading to a file hosting web site and linking on to this thread.

Check the injectors resistance and wiring continuity/shorts per the service manual.  Do the injector resistance tests with both cold and hot engine.  Hose testing won't heat the injectors enough, take it out and run it hard on the water.
Also check the large blue smoothing capacitor 55v/SAC 30v for swelling, seal leakage, loose wire screws and internal leakage shorts.  Check the blue capacitor wiring for insulation wearthroughs, crushing or other damage.

Dkgroup - were you able to determine the problem/solution? I am having a similar issue in my 04' 200hp E200FPXSRB
