It's the end of the season, sadly. I bought my Max like 6 week ago and i had a strange issue with my coolant system. When i first did my 25hr i dropped the oil and changed the gas filtrer as needed and i've checked the prestone level to see where is it and surprise, no prestone in the bowl. there is no leak, the motor is shiny.

I called Sport Marine and they told me that maybe there were air bubble in the system, so full it back up and now after another 30hr, there is still no prestone in the tank..

Any idea ? thanx
