Hi ausieman I knew about the boat licence which I have now but I have been looking at the seadoo as you know they have the closed cooling system with a auto cut off if you did capsize the ski. I do not know much about the mechanics how ever but have been informed of a dealer for bikes and skis can take you for a ride when it comes to the servicing of them.
I know to keep the engine in good condition would be to keep them in the Murray but we live close to Moana so would like to get the ski in the sea.
I was told by someone the supercharged skis would take a lot to fill and could empty very quickly if you riding the ski long and hard.
I will have a look around for the skis you have recommended but thanks for you reply food for thought.
