Where's my thermostat???

[ithrowgirls]

I have a simple question for you all. I have an old OMC with a 3.8litre GM, Buick, whatever it may be. Anyway, I purchased it recently and the hot light came on when I took it out! So, I pulled it out of the water and started an examination of the cooling system. When I opened up the thermostat housing, I found no thermostat!! Could this be the cause of my overheating??? <br /><br />Any info greatly appreciated!

Not likely.<br />Are you FWC or RWC?

People usually take them out trying to solve overheating problems, start from scratch with your diagnosis - pump, thermostat, clean system etc. What you check depends on RWC or FWC.

Hey folks, I don't know what FWC and RWC mean.<br /><br />sorry.

RWC is raw water cooled - the water that the boat is floating in runs through the engine to cool it, not a good system especially if you use the boat in salt water (salt very bad).<br />FWC is fresh water cooled or antifreeze/boil cooled, the engine has a heat exchanger fitted (boat equivilent of a radiator) the outside water cools the heat exchanger, no salt water goes through the motor - much better system.

The thermostat isn't sitting there like a car. Look up inside housing it might be there. It is held in by a o-ring. buy a manual. Check impeller. And donthrowgirls

Correct, it's up inside of the (massive!) thermostat housing.

It's RWC. Fortunately, I don't use it or plan to use it in salt water. Fresh water machine. <br /><br />To tylerin:<br /><br />I appreciate the kind and helpful advice.<br />1. I have a manual and have been checking through it. It's explanations are not always the greatest. Perhaps you should purchase and/or read one and you will know first hand what I'm talking about.<br />2. If you read my first message you will see that I opened up the thermostat housing already. That is how I know there is no thermostat in there. <br />3. The sterndrive impeller is in good condition, already checked it. <br />4. I will continue to throw girls. <br /><br />Thank you.

Obviously I offended you. It wasn't intentional. Many people don't see the thermostat hiding up inside housing, thought I could help. Seeing that impeller is most probable cause for overheating I thought I might suggest checking, and Everyone needs a manual. As for the donthrowgirls, I hope your kidding!!

Tylerin:<br /><br />I apologize, but I thought you were attacking my intellect as I've seen so many bozo's do on this type of forum. In my mind this type of forums are a great resource for those of us (myself included) who are new to the world of boating, frustrated with their boat or have simply no idea what to do next! I simply (and I'm sure most would agree) like this type of site because it is very helpful. If I ever have any info to give, I will be willing to do so. <br /><br />Thanks for your input. Sorry for taking it the wrong way.<br /><br />ithrowgirls<br /><br />p.s. Cheerleading is how I came up with my name.
