View Full Version : Operating Temperature

09-05-2007, 01:11 AM
Just bought an '06 LSV with 325 EFI. Ran for about 3 hours Monday. Noticed operating Temperature was around 175 all day. Specs say normal operating is 162 deg. Should I be concerned? It never went any higher than what seemed like just below 180... My Outback with 310 Carb always seemed to stay around 160...

Just curious..

Warmer lake temps will have it up a couple degrees. But I'd say 175 is nothing to be concerned with

Usual temp on my V-Drive is around 180 all the time.I run it on the sea always.

I would say that 175 is definately ok. Anything below 210 would be acceptable. I would check the strainers if you have them as well as the intake on the trans cooler for debris just in case. Mine normally runs 160, but went up to 180 when the trans cooler became partially blocked. The trans temperature went up and brought the engine temp up since the trans cooler was only half working due to the blockage.

I clean the strainer often, but maybe I should remove it and clean the line also.

Thanks on this one too,Jesse. you are very helpful. :)

Thanks Jesse.. I was spoiled with the Direct Drive having LITTLE to check on.. I am still learning the V-Drive Differences.. I am thinking I should probably have the boat completely serviced just to get a GOOD clean start. Just don't want to give up a weekend so I may do that Monday!
It was winterized at 105 hrs last fall and has 138 on it now.. I am trying to find out any service done now.
I hope to spend some time this weekend getting to know the engine / drive a little better.. I store it 15 miles from the house so it is difficult just to walk out and check on it...
How was the beach?

my 99 310 hp carb lives on 175...

Thanks for the info.. I am guessing mine is within range.. There could be a little dirt/etc in trans screen or something that is blocking a little flow.. plan on getting some service sometime just to make sure all is good.

Thanks Ed. I bought from a guy in Tennessee and I bet their river is cooler than our river in Mississippi... It never got any higher, just thought it was a bit warmer than my 310 Carb was on Outback. I'll keep an eye.. I guess you are always a little more overprotective when you just get it.

when i had my 02 carbed outback, it always was on 160. then i bought a 05 supra ssv 22 325hp and it was always on 178. never could figure it out.

dealer had no idea.

never had any problems or issues.

Ready to get in water tomorrow!

You know, my outback hasn't been below 180 since I bought it. My dealers mechanic even questioned it one time when he came out to fix another blown hose, and live in Wisconsin, it's not like our lakes are that warm. In fact was out tonight and is still running at 180. :?

My '04 OB stays right around 170. Been that way ever since I've had it.

my LSV is right around 170 or so most of the time. I have always heard that 160-180 is normal

Our Plant manager ran a mechanic shop for a long time. He said the gauges are not the most precise piece of equipment... SO my guess is they are not Perfectly accurate. I don't know if the computer your dealer can hook up to the motor can give an accurate reading... but his point was they are probably off a little which could explain differences between all of us...
My guess is if it is not rising and staying too high, we're good.

That would make sense.

My '99 Outback was only reading around 125 for about the first 5 or 6 times I had it out after I bought it. Then a few days after it got to 200 until I started cruising it went back down to normal.
I inspected the impellar and sure enough it was trashed. Replaced that and temp gauge has been staying right at 175 so I'm not sure what was up with it before reading at 125.....

Aaron - Bet you were cruisn' the Illinois River. If so, maybe the impeller picked up some trash let through when the damn was opened. We were on the river recently and had to keep watch all day to avoid some potentially damaging debris. :shock: We launched at Starved Rock Marina and set up on the beach area east of Columbus Street bridge. Pretty interesting when the mega barges passed by. Hope you get everything worked out. - Deerfield

My 07 Outback always runs at 180. 325 horse EFI. The service guy hooked it up to the computer on the lake one day to check out my pedal postition sensor. The software said that the boat was actually running at 158. Its common for the guages to be off. I just use 180 for the baseline temp. If the boat gets any warmer I know the strainer needs emptied.
