I ru keep the read somewhere that you could run for extended periods on the hose if you put water in the hull to keep the carbon ring cool. Any truth in this - it would be useful for checking the oil level before we leave home. I guess the next question is how do you keep the rideplate cool? Last time we were at a dealers, we noticed they were running closed loop Sae-Doos WITHOUT a hose for 2-3 minutes.
