8v92 ddec 2 engine operating temps

[encantotom]

Hi all, i just picked up my new to me 1990 38' newell this weekend. we drove it home 550 miles and it is really a joy to drive. the frame has 122k miles and the engine has 17kmiles since majory overhaul. i have a question about what temps you guys see on your engine during normal and steep grade driving. during night at 70mph it was 180-190. during the day as high as 200, but typically lower. but going up a 6% long grade it seemed to get around 220 or so. to be honest, the graduations on the vdo temp gauge are not linear, so i think it was around 220. it cools down quickly once off the grade.i slowed way down to 45 and drove in the power band in lower gears to be sure. no engine lites came on. what is normal for you guys? i am headed off on a 2 week 4kmile trip on tuesday, so would like some comments from you pros. thanks.
