Evinrude etech 25hp problem

[ECHOSIDE]

Ok. So I have a 2012 25hp evinrude etec that runs for about 15 min then shuts off like it got to hot. It will restart when cooled but then only run for 10 min again. It has new water pump and thermostat. Been at dealer and they just throw parts at it.

Any ideas?

Is it in fact hot when it shuts down? Too hot to touch on top of the cylinder head? If it's a salt water motor or a river runner, there may be salt or silt in cooling passages. Make sure the intake is clear.

did the dealer look at the engine report for trouble codes...I am not familiar with 25hp but it is an ETEC with the EMM and should provide fault codes to explain the reason for a shut down. It must be bad otherwise ETECs go to safe mode and drops the RPM

why don't you check out the ETEC user board for I2 engines and ask
you can do a search for 25hp to look at similar reports…
one report talks about shut-downs due to a bad coil

No it does not feel hot when shut down. They said there were no codes present.

very odd…. could be a fuel issue is this a new problem for you is this a new to you motor

if you pump the fuel bulb will it still conk out or keep running

tank vent open ?? try to run with no fuel cap on the tank

tank fuel pick up blocked partially have you tried a different fuel supply incl a different hose
