Hello !
Thanks for your comments.
This launch is fast but not as fast as those of our friends in Cabariot.
The propeller is a Propshop 4x blades ,60 mm .
I don't know nothing about the autonomy as we sailed for 1/2 hour and get back with some gas & water left . Maybe , we could have sail for 10/15 min more with no problem. My gas tank is small and I am not sure that I could sail for more that 40 min. To be checked.
I am installing an old regulator that has been in my drawer for years. I let you know the result! I have to test it out of the boat before to install it inside . We had enough fire this summer to add one arsonist steamer!
Best regards.
