View Full Version : Operating Temp

06-28-2006, 10:29 AM
Perhaps this question has been asked before, but what is everyone's operating temp. My 04 Indmar 5.7 carb is running at 180. At least it is consistant. The thermostat in the Indmar manual states 160 on the specs page. Change the impellar every year. Should I change the thermostat? Thanks for your help

160 to 180, depending on how hard I push her

I run at 160-180 340HP EFI. When I'm pulling with the tanks full the temp stays about 180.

I have 2004 outback 5.7 carb, with the heater and it always running at 180.

OK so you guys are about the same.. just making sure no problems with thermostat. Thanks for your replys. Hope everyone has a fine 4 day weekend. Lots of boarding, skiing, tying up, and moderate arm curls planned here. I have a few ruthless buddies that have the new Kite tube.... they break that thing out on holiday weekends. One of them fell Memorial Day weekend from at least 20 feet up, black and blue and spitting blood.... this ought to be fun to watch again. Everyone be safe.

That kite tube is brutal. I am over 200lbs so it doesn't work for me. My 12yo daughter got about 10 ft of air under her and rode it for about 30 seconds. It was amazing. It definitely seems to be a doctors best friend, though. We have had a concussion and a separated shoulder so far.

Be safe,

Sometimes, you just got to ask yourself..........what was I thinking?!?
.....just because you can do somethings doesn't always mean you should.......
Have a safe holiday weekend (starting today and all next week for me. I don't have to be back to work till the 10th. But don't feel too sorry for me, I will try to survive as best I can)
