Been using this stuff for years in my cars. It helps keep the coolant cooler. Anyone try it on thier 4tech seadoos? Since im going to the desert in teh summer where it reaches 115* during the day the cooler the engine the better.
I use it in a few of my bikes... and it's a good product, but even in the middle of summer, the lake water will only get into the 70's. Plenty cool to keep a 4-tech happy. But put it in if it make you feel safer.
