My YS 120 needs rebuilding now, but when it was fresh it would turn the 17 X 6 at 8900 to 9200 rpm. I use 20/20 fuel.
Right now it will only get about 8000-8200 rpm on the same 17 X 6.
I'm figuring the DLE 20 may be a little short of what I need for power.
My Funtana is at 10lb 2oz with the YS 120, and would be about the same with the DLE 20.
