This is something I have been thinking about for a while, you think your ski is running hot, but how do you know how hot is it supposed to run ? I realize there will be some variances in temps as they come in from different places with varying water temps this time of year, also on some models like Seadoos worn wear rings would skew the results but if we get enough info we can get a baseline to work off of and at least get an average.
I started this thread over at PWCT , I thought it might be of more use over here so I have compiled it and posted it here , some of these were given to me by others and I appreciate the input , I will put who gave me the info if I know who did , also if you have something to add to it PM me and I will gladly add it here , the more info we have the better.
I am going to post up temps recorded with a non contact infrared thermometer on skis I test run, hopefully some other people will do the same, that way we have a database to work off of, infrared thermometers are fairly cheap, I just bought a Fluke meter off of Ebay for $35.00 shipped.
. Temp readings taken at the front of the head but I did take it in several places they were pretty much consistent . All temps were taken after running the ski with it in the water at idle .
Someone PMed me and asked if my Fluke tester was accurate , that theirs was off 8 degrees , first question how would you know if it was off 8 degrees or not , the second question is does it matter, 8 degrees one way or another is a variance, something running 191 degrees or 175 degrees when it is supposed to be running 183 really would not concern me that much for the purposes of this database .
If we get enough readings we get an average and a ballpark temp of what stuff is supposed to run at and rule out margins of error. About the accuracy of my Fluke tester , I did a test and took a temp reading of the inside of my mouth 98.6 degrees , I also tested an ice cube and got 33.2 , my equipment is close enough.
2006 Seadoo GTX 4tec 155HP 184 degrees
2006 Seadoo RXP 4TEC 185HP 183 degrees
The two above are closed loop cooling systems, we can assume 180 degree thermostats by the temp readings.
701cc engine in jetmate:
Cylinder temps where around 130-145 while idling/cruising and only 115-119 degrees while running at full throttle.
'03 MSX140.....1200cc 130-140* degrees
Polaris Vrage Txi , Genesis 1200 carbed and Ficht 130-140 degrees
Polaris SLT-SL 750 -780 140 degrees , Polaris temps were submitted by Myself, thanks
Yamaha VX1100 deluxe 108 degrees (yeah I know it sounds low)
Seadoo GTX 787 engine 128 degrees (wear ring bad will check again with new wear ring)
I will be adding a few more in the next couple of weeks as I get some more skis out the door , and I will start recording water temps of the lake as well to see what if any difference that makes in the readings.
