Not to rain on anyones parade, but I had the Moki 1.35 and turned a Mejlick 18x8 at 7700 and APC 16x10 at 9000-9200. The motor did not like the 18 inch prop but it was turning it as hard as some these 1.8's. My motor had about 2 gallons on it before I sold it. I ran Omega 5% for both gallons. Kinda strange that the little motor turned the big prop the same as some of yall's big motors...wierd!
