I do know that MERCURY set there overheat alarm at a very low temp. A friend had a 90 HP and 2 little pieces of grass on the pickup would set the hot horn off.

yea that was me with the sand issue...still havent figured it out...i have changed thermostats,heat sensor switches...pulled and flushed heads/powerhead, new waterpump and impeller...still overheats.....i bought a laser thermometer and was able to figure out which cylinder was over heating.....i then pulled the thermostats out and it runs 30 degrees cooler on that cyl on the hose, i havent been able to run it in the water yet.

sure hope yours is easier to find than mine has been.

Well, I when to church this morning and prayed for patience, then I stuffed myself at Golden Coral.

Then I removed the thermostats. I doubt that they were slowing down much water.



Buttoned her back up, started and ran for about 3.5 minutes before the alarm came on.

AAAAAHHHHHHHHHHH!!!!!!!

Kajun has turned me onto a Merc. Mechanic who helps people online (thanks dude), guess I'll see what he suggests next.

You can see that it pees good at idle.



I did stop in Walmart after lunch and pick up a couple items. Some 5200, some silicone sealant, and a new winch strap (the hook is tied on to the old one).

But instead of doing anything else to the boat today I did what any good southern dad does on Sunday afternoon, I gathered up the kids for some shootin practice.
