Filling the antifreeze
on a completely empty system what is the best way to ensure the antifreeze is circulated thru the entire system?

When I changed my thermostat I reference the 2007 owners manual page 117, below is the link. It was pretty simple to do and better with two people. Leave the drain plug out while filling the resivoir. Once air stops coming out of the drain hole in the rideplate, after about 5 more seconds put the drain plug in. Top the resivoir up to about 1/2 full or maybe more, the engine will suck it down. Run the ski to operating temp and fill resivoir acordingly.
I used Prestone premix that is good for any color coolant. I think I used 1.5 gallons.

You can bleed 99% of the air out of the system by leaving the cap off the resevoir and squeezing the rideplate hoses and the hose from the head to the thermostat. Leave the coolant topped off on the highside and ride it.

Well it didnt go to well. Just as fast as i was pouring it in it was coming out.
Putting a mirror down in the bilge area the problem was readily visible. The bottom tab on the new rotax thermostat was not all the way seated. having to pull the intake, ic piping, just to the thermo i was ready to scream. The tabe was removed, the thermo reinstalled in 8 minutes as hail was pelting me.
I have to say now I know why I prefer working on robots and computers than any thing mechanical.
