morning all. the last 2 times i was out i got this long alarm when trailering my boat ( idling basiclly ) mine you i can go up and down the lake
and i get no alarms and everything seems to work fine. some says the temp switch in which one of those are pretty pricey.
 
The alarm can got off for at least 3 reasons, I believe anyway, if that's a 60 degree v6 fastrike/eagle-series/looper, anyway (real problem or alarn malfunction): . 1 - VRO/oil level related oil issue, 2. Heat 3. Fuel vacuum.

Probably does for over rev too.

You gotta figure out which alarm it is. Make sure you oil injection looks sane, I'd honestly run a quality oil at 75:1 in the fuel util you are sure it's getting oil - little extra oil doesn't hurt much, will save an engine from burning up during trouble shooting provided you got easy on it if the oil injection is failing.

If it occurs, try the squeeze bulb - if it is collapsed and you can't even pump it you got a vacuum issue.

Most likely culprit is temperature. Water pump, thermostats, is first attempt, which if not done in the last couple years (or subjected to abuse) shouldn't be questioned as a likely cause. These engines all idle & do low RPM, notably warmer than they run at say 2500-4500 RPM. And when there's a cooling issue, particularly so - they tend to overheat at < 2000 or > 5000 RPM. So running ok when flying across the lake doesn't indicate all is well if you have low RPM alarms, more so it proves something is wrong and it's not a false alarm.

Have you serviced the water pump ?----Needs new impeller every 5 years.

water pump was done a few months ago T stats are good and opening and closing at a good temp
as they should and the tell tail is pissing good as for adding oil i do it all the time for this type
of reason. and for the bulb I'll squeeze it and squeeze and seems it won't get real hard ( might change this one ) starts tho.
i may have the original VRO any way to check it? some threads i read lead to temp switch / port .
thx for your time. hate when these things pop up.
