Thanks for all the information. After machining down the fins into an outer button, do you know if the Supertigre .18 jacket will fit once the hole in the middle is enlarged?
It looks like it will work, but I am unsure.
Thank you for all the help.
Do I need to just run a brass line around the turbo head or should I purchase a liquid cooled head from someone?
Also, does anyone know if the OS Marine Head Assy. for the older liquid cooled .18 will fit this motor? The part number of the head is 18cvr-m
Thank You
