I'm sure it's not overheating most likely it's a chaffed wire or other bad connection. If the sensor wire is chaffed and grounds out it will throw the code. Finding it is the issue. Every time you take it in repeat what has been done to it so far
All I have found is turn key ON (do not start)
Use Tach or or command link button and work your way to maintenance hour screen
Press and hold SET and MODE buttons for 3 to 4 seconds
Thanks
I did find it, was looking right over it at BAM. It shows DDIS, EST and "conventional ignition". Did same thing at Marine parts
Merc old number NLA is was 810827 then 8M0082721
Thanks
He said 1980's so I looked for 80's model 3.0 (link above) because the serial number did not list points ignition, it either had DDIS or EST. I'll leave it to both of your knowledge and bow out
If it was my boat I would ditch the points and switch to Delco EST
These new motors need a scanner to find out what's wrong with them.
A one beep can be many things, electric power (bad connection), communications error, fuel pressure and a few other things
For me it looks like a fuel pressure issue if your gauge is accurate. It takes very little gas to rev the motor when not under load, and a lot of gas under load
Should see around 40 psi with key on motor off, fuel can drop off a little when pump stops but should not drop much.
Motor running 38...
Is this a new to you boat?
You say fuel pressure is within spec, is it 43 psi?
Put a fuel pressure gauge on the rail and see what the pressure is from idle to WOT
Thanks, that is different
All the ones I've worked on which were Mercruiser with VST it was just a float valve. It filled up and would not allow more fuel in until it was used up
Oh and one my current outboard motor serial number is 3B384246
Don't know your serial number, and also have not heard of a float switch working like that. Not saying is doesn't just have not seen one that worked that way
Put a fuel pressure gauge on it and see if your loosing pressure. If you do loose pressure start with the fuel filter and work forward thru fuel pump to injectors
Took a month (no s) my mistake
Basically seller said I sent the item and here is the tracking number
Buddy said I received box but it was not the finder
Final thing was Buddy called his credit card company and disputed the charge and got his money back
Amazon and Walmart is the middle man and takes a percentage of every sell. They both use sellers which are not vetted. Buddy bought a new fish finder and was sent a tracking number. Box arrive and had a small cable in it and no finder. Took months to clear it up
