    Engine Water Temp?

    Anyone know what the average water temp of a fully warmed up engine is on the GPR.
    I want to install a temp gauge and this would be help in gauge selection.
    Have over 3 months till I can find out in the cold State of Michigan.

    Thanks

    I by no means am a GPR expert but it is going to depend on what the temp of the water that you are riding in. There is not a temp regulating device (thermostat) in the GPR since it is an open loop cooling system. Someone might have a close range but I have no idea.

    I agree the water temp and air temp will be a factor.

    Most gauges start at 100degrees and go to 250 degrees, and I believe the 100 degree starting point will be to high.
    I believe it will be a lower range that is needed.

    I would agree. I would think you would want something that would start around 80 degrees and only go to about 125 or so. This would be the only way to get the increments where you could get an accurate reading. BUT, you could always go digital.

    I found one that goes from 60-140 degrees and its an analog meter by Auto Meter.
    That should cover the range it will be running.

    WOW!!!! I wouldnt have figured the water would have gotten that hot in the short period of time it is in the engine. But like I said, I'm no expert.

    It's an open loop system, so it's dependent on the water temp in the lake you're in.

    Ever felt the water coming out of some pissers? I remember riding Fercho's triple pipe ski, when he had the pissers in the front of the ski. As I'm hitting 80+ (remember, this was probably 4 years ago, so 80+ was great) I remember thinking "God, what is that burning my right leg?".

    j-me plumbs his head water thru his handlebars and grips for heated water in the winter, and he has pisser hoses spraying down into the footwells. it gets hotter than most people think.

    I think it was John Abbot who talked about a 10 dollar probe that can be bought at Academy sporting goods stores. Fishermen use it for measureing water temps.

    I ran down and bought one. I temperarily taped the probe to pisser in the back of the boat. I know that it is not completely accurate, but fairly close.

    Group K sleeper 1200 in 62 degree water:

    idle speed 75 degrees
    wot speed 146 degrees max temp.

    I honestly thought that this was a high temp and that 120 is what was the target.
