Hi, I have the 2 beep every minute issue after the boat has come up to temperature. Temp Gauge showing 170 and stable. Always shows 0 - 170. I have today replaced the IAC and cleaned the inlet / butterfly area with carb cleaner, New IAC filter with no resolve. I noticed today that the Exhaust manifolds are very hot, too hot to touch, however, the Risers are cold. Stopping the Engine and then restarting, the beep continues every 1 minute or so following restart. Boat idles fine 600rpm and seems to perform OK, seems a bit loader than normal. My question is - "should the risers be cold when the manifolds are too hot to touch? what could be the cause of this issue?
Any help appreciated
