Water temp warning ?

[2kvert]

Hey folks.
I have a 2014 etec 250 ho.
The last 2 times out, while just cruising my water temp light and alarm will go off.
I'll slow to a no wake speed for a bit and it goes back off.
It's still pushing a good strong pee stream, the water in the stream isn't hot.
Where should I start?

My 2016 150 etec is doing the same thing 72 hrs never had water pump replaced Mechanic is starting with changing my water pump

Pull the thermostat and make sure they are functioning. Is this motor used in salt water? I would take an infrared temp gun with me. Pull the motor hood, run it till it goes off and then get down to idle and shoot the head to see actual temp and confirm it's actually overheating.

I ask if it's salt cause you could have crud built up on the internal cooling passages.

Got boat back today. Was the water pump

That's good. That's usually what it is. 2016 is a good run on an impeller, especially if it's used a pretty good bit.

Thanks guys. I ordered a pump and thermostats. Starting there because I can do those. It's a fresh water boat.
I'll keep u posted

When back up and running, don't trust gauges (or don't fully trust them). Check the tops of the heads for temp. (infrared tester is a good investment).
