LY6 Thermostat

Recommended Posts

racer808

Do any of you have the LY6 motor?  Do you know where your thermostat is, do you have a remote thermostat by chance?

My boat has held a steady 160 degrees since I've had it.  It acted up end of last year running cooler then was back to normal this year & now it's running cold again.  My only guess is all the algae in our water has perhaps stuck it open or it just needs to be replaced.  I have the new thermo & gasket in hand.

 The problem is the thermostat is not where Indmar says it is & Indmar / Engine Nut has no idea where else it could possibly be & are scratching their heads too.  So, anyone by chance know of a possible place it might have been installed?  It makes no sense, I've taken everything apart a hose connects to & there is nothing, there is nothing in the block where it should be.  

Since it seems I might not find this damn thing, is there any harm in just putting the thermostat I have where it belongs?  I know it's a bandaid & would love to find where the heck the existing one is but I don't see it happening.  If Indmars confused, I am sure as heck not gonna figure this out without some help...

 If there’s nothing in the hole where the thermostat is supposed to be I would guess that maybe somebody messed up and didn’t install one in the first place. I’ve never heard of a remote thermostat but I suppose anything is possible though.  If this is the case I can’t imagine the harm in putting one in there.

When I saw it was you posting this the first thing that came to my mind is that dirty lake!

Do you have closed cooling?  If so, the thermostat may be installed at the input to the heat exchanger.

It seems less weedy but really dirty this year.  Too bad we got about a week maybe two of water left.  I'm gonna pop the thermo where it belongs and what happens.
