wow you have some rocker. What boat do you have?

Well maybe the stern Jack will help help keep it down by turning props farther down but I doubt you Wil get more speed. It sounds to me like you don't need any leverage. A stern lifting prop might be better avenue. Round eared gives bow lift. Clever style gives stern lift .like hydromotive . Ask the guys here about that. There are some very knowledgeable people on here. B Blades can help answer . And the admins here are very knowledgeable. Really dont think stern Jack will do good. It sets back but props will basically be same depth becuase the water comes up as it exits the bottom of hull .someone mentioned that earlier. You need higher drive hieght and or different props

I see this is really old but if you still have it, I will buy !

I see this is old but, if this is still available . If will buy ! Thanks
