    I have twin 2013 QSB 6.7 480 HP with 1,100 hrs. On our last offshore trip this alarm went off. Engine temperature was 174 on both engines. Running 2850 RPM. Only thing I can tell you is that it appears the exhaust “smoke” on the port is more than starboard.
    Thanks in advance for your help.

    Sheesh , I suspect that smoke is steam from lowered raw water volume.
    I have posted my tome below. Read through and ask if you have questions.

    What is “this alarm” ?

    Got a picture of the alarm code?

    What displays do you have?
