If I understand the question, it is two part:
1) Is 180 degrees too hot? I believe the answer is yes. 2) Should lilltech be using a lower thermostat? Don't know the answer, because I don't know what's in there. I believe the proper thermostat is 140, but I'm not positive. Someone else, I'm sure, can confirm. BKH |

My BFN runs about 180 after running WOT for more then a minute. As soon as you back off WOT it takes less then a minute to cool back down. Yes I believe 180 is to hot for normal operating conditions. Your 87 should have a 140 t stat in it. Under normal power the BFN runs between 145-160, depending on lake temp and what I am doing.

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 have a mechanical gauge screwed into my intake,That way if i suspect something is wrong I don't second guess my electric gauge.

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.

What I was told by either White Lake or SkiDIM (cant remember which, maybe both) is that the carbureted PCM 351's want to run at 160 degrees. 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. |

running hotter usually promotes better fuel mileage and longer ring life. Thats why alot of todays cars run 200 degrees. I dont know about a boat but I would assume the same would apply for the mileage and ringlife Unless a different type of material ring is used to make it last longer at lower temps.

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