operating temp?

[motosno963]

What's a good operating temp for the outback. Seems like mines running around 180-190 and when I grab the rubber hoses that the water runs through, it feels like there's barley anything running through the hoses. But if I do the fake a lake in my drive way it spits out a good amount of water..

That seams a little high. I run about 160. I would check your impeller and if you have a strainer that too. You have to remember that on a fake a lake you are forcing water into the system but at the lake the impeller is sucking water from the lake and putting it into the system.

Mine runs around 170... Not sure how accurate the gauge is though.

My 98 runs about 180 to 190 brand new impeller because I was a little concerned but seems to be ok

ok..i just replaced the whole housing and impeller 2 summers ago..

What about the actual water pump on the motor? Have you ever replaced that?

Do you have a strainer ? If so be sure the threaded fitting are sealed and do not twist ,the pump will pull air in and cause this issue , i had this problem on my 05 LS

Mines runs 180 - 185

Just had a thermostat go bad after one season only. Rare but it can happen.

It's basically just a SBC high flow style. Typically they are 160 degree so your operating range shouldn't be too far from that.

I have a strainer and I tighten it hand tight so I dont over tighten it and crack it. I replaced the thermostat like summers ago but I forgot what temp setting it was for..but I mean you can still run one without a stat and it would run cooler.. also I have seen some of the pumps themselves on eBay for like 80$ I think..aglfter I do the oil and get a new deep cycle batt for the boat I'll maybe pick one of those up

I didn't mean the strainer cup ,i meant the threaded input and output fittings, they should be sealed and not twist or the pump will pull air in , giving you a high temp reading , heater not working at low rpm , my 2012 LSV was showing symptoms and sure enough it was the fittings as well.

[motosno963]

Ohh the input and output on the strainer itself?. Maybe I'll take them off, inspect them and put some thread tape on them

My 98' outback is usually around 170. I replaced the pump and impeller this past winter. Sometimes when I'm at idle it might go up a bit past 175 but not much. As I throttle even just a little bit, water is pulled through and cooled.
