Thank you Marty and Kevin. I found some better hose clamps at a wood working tool supply near by.
The clamps have a round bar on one end and the regular "C" clamp screw end on the other. Anyway
my problem was the old small "C" clamps I was using. I have now filled the motor with Antifreeze and it is holding. (no leaking) I know the motor is full as I put in more than a 1/2 gallon and it now has antifreeze in the fill hose funnel that is still in the cylinder head. I will check out manuals for this boat on line as you suggested. Thanks again Rick

i`m wondering if you couldn`t use a utility pump and pump straight anti freeze through the back flushing connecter?

Thank you Kevin, that is a big help. I am 68 years old and I had trouble bending over into the boat
while installing the dran hose clamp. I think this is why the antifreeze ran out. I will clamp it again
using your suggestions. I will let you know if I have better luck. Can you suggest the best manual
for this 2001 sportster LE with 947 Rotax motor?

Welcome.
