Motor running to hot, not sure what to make of it

[Ola]

Now i tested both 5s and 6s, geared to 40 and 41mph..

Both times i read 165-170f after 20min run in 30`f ambient temp.. As last time in snow, with max paddles rear, badlands front.

When the outside temps hit 75-80,and i got real traction, then what... hmf
