'06 DF 250 stops running

[Ron2019]

I've looked through the forum and didn't find anything similar. Here's what I have going on. Motor starts fine, and runs great, until..... After a couple hours of running, motor quits. This only happens when in neutral or at idle sped. I've noticed a single beep about every 15 seconds while running at speed. Thought it was overheating, so I changed thermostats and water pump. Problem still persists. Any ideas?

there are a couple of things that can cause the alarm
are your getting any warning lights at the same time as the buzzer goes off?
any "check engine" lights?
Battery new or fairly new? low battery volts are a problem
the ECM needs constant voltage and if it is not getting power
there is a 1 - 1 code for low battery voltage
low oil pressure creates series of long 1.5 second beeps
give us some more detailed info

2017 susuki 25hp outboard stops

I just hooked up my 25 hp Suzuki outboard to my pontoon boat last month and it has a bad habit of stopping and not starting. Acts like it is running out of gas. Plenty of good clean 89/91 octane fuel, squeeze the bulb and can squirt fuel through the fuel filter. After sitting awhile it will run for days then just decide to stop again. Oil level is good...thinkin fuel pump...no local Suzuki dealers nearby and its under warranty.. what to do

@Davidprof, open a separate topic please. Here we are trying to help Ron2019

@Ron2019, is there a good tail after the change of the impeller?

No warning lights....gauges disconnected when I purchased the boat. SMIS quit on me a while back. Just installed new Raymarine mfd, in the process of connecting engine to mfd...if tier 2 at Raymarine would answer the phone...lol
Batteries are a couple years old.
Not sure if it was mentioned, one short beep every 10-15 seconds when issue pops up.

@Ron2019, is there a good tail after the change of the impeller?

By tail, I'm guessing your referring to the pee stream. If so, yes, its been fine all along, before and after impeller change. Old impeller looked good, no pieces missing.

It could indeed be a low voltage problem. In idle or neutral the output of the alternator is significant lower than at higher revs. In neutral the battery voltage can drop to much and cause the alarm. It could be worth to change the battery ('s)

Then what would explain the beep while running at speed?
