G23 Warning SPN 441 FMI 15 keeps coming on screen

[Indy Rob]

Hey Guys, I am getting this warning, SPN 441 FMI 15, and going to have the dealer check out. Before we have had weed stuff from the lake on the grate on the bottom of the boat and in the strainer by the batteries. I have booth cleaned out and my intake hose doesn't have any "kinks" in it to hinder water flow into the engine. Something I have noticed, This warning only comes up on higher RPM scenario's, so like when I have 3/4 or more ballast to wakeboard. Doesn't affect full ballast surfing, but we are also running low RPM's, like 3300. I have the 450 in my G and I am thinking something is in my line that is causing water to not flow through the engine for cooling. Weighted up my engine temp is 171 to 175 degrees. Not weighted up, with half ballast or less engine runs about 165 degrees. Just wondering if anyone as run into this repeatedly and seems to be clear of weeds etc in the intake area. When the warning comes on the boat idles down with the check engine warning on the screen. Any thoughts on this?

Thanks,
-Rob

Check the cooling hoses in the engine and see if your leaking fluid. My boat had a hose clamp fail and the temperature went really high. Although 165 no weight seems about right. That's the temperature I run a lot.
