What should I do if my MerCruiser runs too hot?
All it takes is 45 seconds of running dryand the impellar is ruined. Make sure you have a good set of flushett muffs that won’t fall off while you are running on the hose. The water pump might be fine but it’s a good place to start. The pump should be replaced each season. If you are overheating and you haven’t replaced the pump for a while, do it.
Why is my car running hot but not overheating?
If you find that you’ve got a car running hot but not overheating there might be a few reasons: 1 Clogged or damaged radiator 2 Low coolant level 3 Damaged water pump or thermostat 4 Overworked engine More …
What to do when your car overheats at high speeds?
A rag stuffed into the T-stat hole will help keep old scraped gasket materials out of the T-stat port. Just carefully pull the rag up out of the hole. A wet rag will help keep the gasket material stuck to the rag. Carefully blow out the water pump housing with low-pressure compressed air. Use the new gaskets and replace the T-stat and water pump.
Do you need a 3 Row Racing radiator?
The need for a 3 row racing radiator is a band aid for an issue that needs resolving. Most engine coolant systems are fairly straight forward and simple to pin point the issue should not be a daunting task.
Why do some runners adapt to the heat?
Because of blood plasma’s important role in the cooling process, training alone provides a bit of adaptation, because a side effect of running is an increase in total plasma volume. This helps to explain why the fittest athletes (and likely those with the highest plasma volume) typically adapt more easily to heat.
What’s the best way to warm up a truck?
With engine cold elevate the front of the truck as high as you can get it. Floor jack. Pull radiator cap – make sure coolant is fairly full. Start truck – set heat control to max heat and let truck warm up. The elevation may push the trapped air out. If this happens, you’ll begin to get heat after 10-20 mins.
Can a distance runner run in the heat?
Still, heat acclimatization can take you only so far during weeks-long stretches of sultry weather. Steve Sisson, assistant coach of women’s cross country and track at the University of Texas, knows well the impact that prolonged, inescapable heat has on distance runners.
How does the temperature affect your running performance?
Dehydration from fluid losshas a profound effect on running performance—a loss of even 2 percent of body weight leads to about a 4-to 6-percent drop in performance. Furthermore, both temperature and humidity increase heart rate and amplify these effects. At 60 to 75 degrees, heart rate increases by two to four beats per minute.

Why does my Mercury outboard overheat at 3000 rpm?
Replaced water pump impeller, t’stats, poppet valve and still get overheat alarm after running a while at 3000 RPM. Have water pressure and motor pees a steady stream. I understand the motor has a filter screen somewhere in the water system but the powerhead has to be removed to get at it.
Can you change the carrier on a Mercury outboard?
I wouldn’t recommend changing the carrier. You can go to the mercury outboard website and enter your seriel # in the parts express and get the schematics and part #’s. Your local boat shop might have all these also, but go look at the picture anyway.
How to access the poppet valve on a Mercury outboard?
The easiest way to access the poppet valve is to remove the lower part of the cowling. There are 4 small bolts/screws that you remove,2 in front, 2 in the back, then tap the lower half gently w/rubber hammer. Then it very easy to get at the poppet.
