Water temp at zero, goes up after shutdown

Chrisvr6

Haven't had a chance to mess with it yet. RinkerYan, why was your gauge going backwards? 

Chrisvr6

Nah. Flying back home today. Might mess with it this week. Can't wait.

Do you guys know if I'm supposed to have the o-ring in the pic installed anywhere? Dont think i do and it would make sense as to why my temp is too cold. The thermo is just probably floating around in the housing. No seal being made. 

Chrisvr6

This one is for my serial number but doesn't show that o-ring like the other pics.

Now look at this kit. http://www.iboats.com/mall/partfinder/?cart_id=338586133&gd_get_grid=1&gd_grid_id=1864&gd_poid=109065&gd_row=148&gd_search_14878=454&session_id=344431261

I have #6 pit in. Its a cork gasket. Wondering if the rubber o-ring goes in the housing above the thermostat to make it tight? I have to get to my boat and check if its in there sloppy. 

Chrisvr6

Yeah, the cork gasket does. 

Chrisvr6

You know, you're right. It describes #6 as an o-ring. I got a cork gasket with my kit i bought. And some kits have both.

Temp back to normal! I did have the thermostat and o-ring on the wrong side of the sleeve inside the housing. Can't believe it. Going out on the Chicago river tomorrow. Thanks guys!
