Water temps what should they be at?

[SpencerA]

I did a search on the web and found a lot of different veiws on where your water temps should be running.

Good snow conditions?
Trail and packed ice conditions with scratchers down?

What is your sled.

My 13 Pro often needs scratches on groomed trails. Especially early in the day.
With scratchers down, I rarely go over 125° on fresh groomed trails.

I ALWAYS runs 125° (+/- 3°) all day long OFF trail without scratchers.

MAYBE 130° on trail without scratchers headed to the truck.

It all depends on how you ride it.
I've had two buddies with 13 Pros this year (both a 155 AND 163) that had to put scratchers down on the trail at the end of the day headed to the truck because they were hitting in the 150s. I vary my throttle, find soft snow and can always keep it below 130 without dragging a heel in the snow.

I know that when my 9 year old was riding their sleds, I HAD to put scratchers down because he'd ALWAYS hit high temps. Sometimes he'd hit 160° before he'd tell me he was getting warm.

3 bars....gauge on XM only shows bars.

128 to 150 is very normal depending on snow conditions. 160 is getting a little warm, 180 to 205 is hot.

My concern is I went snowmobiling with my wife and kids and on the trail (wasn't icey) and scratchers down I was running upper 160's and dipping into the 170's. But I was going at a slow since the 3 yr old just got his 120.

Yep. There ya go.

I keep my revved up and vary the speeds. Stays cool.

My son runs a STEADY throttle at 20-30mph. Gets warm. Up into the 160s. He HAS hit 170 and he pulled over to let me know.

What does the vary in throttle do to help cool a sled? I know the faster you go the more air flow but why would the throttle help cool?

 

[skibreeze]

Going faster allows the scratchers to throw more snow into the track and ultimately, the coolers.

I think as you spin the motor faster the water pumps going to flow more water also

 

[SpencerA]

Another thing I was thinking is I didn't have my snow flap on. I've never ran one until now. I'm curious if that will help lower the tempature.

 

[Scott]

It will help a bit, especially on groomed trails.

I'm no expert, but I always assumed varying the throttle spun the track and flipped more snow up.

good point.

130-160 is fine, 170-180 should try to pick up snow, need to start cooling down, 190-200 need to cool down asap or turn it off, 210-220 starting into damage, 230-240+ most likely damage.

varying throttle will vary air/fuel ratios, has a tendency to blend fuel lean spots. If you unknowingly find a lean throttle position and hold it there you will have a burn down. How many times have you heard the story " I was just going down the trail at 30mph and it just quit"
