temp

i have a 87 cc and it run at about 180 should it have a lower t stat

sorry about the car pic trying to figure out how to post pics (think i got it)

my boats temp runs about 180 degres are they supose to have smaller t stats

i'm not sure whats in there either but it suposed to have a 140 termostat, temp gauges says 180 if thats right or not but it is suposed to run cooler then that

82, You may want to check to see if your temp gauge and sender are ok. Check the gauge by disconecting the wire at the sender and the gauge sould read nothing. Then ground the wire and the gauge should read max. To check the sender, it should be at 240 ohms at 120F, 70 ohms at 180F and 30 ohms at 240F. You can check it on the stove with water being brought up to boiling but sometimes it's just easier to put in a new sender!!!

I thought 160 was a typical t-stat temp...

I've heard 160 also. My understanding is that 140 is the normal thermostat, but alot of people have decided to run a 160 for reasons I don't understand.

I was told this is accomplished with the 143 degree thermostat- the 160deg would cause the motor to run around 180. I cant verify that as I havent change my t-stat yet. The boat does run at 160 with whatevers currently installed.

Ok, that explains a lot. I ordered 3 different 160 degree T-stats for that boat, just to replace it for good measure and have a spare, and all of them went to 180. I figured each one was defective so I just ordered a couple more. I was measuring them in sauce pans on the stove and everything trying to figure that one out. I eventually just said "screw it" and put the old one back in! Amazing. I guess the 140 stat is in there.

I have heard that higher temps in salt water accelerate corrosion of manifolds etc.
