I want to raise my motors up higher on the jack plates, I am having to trim them to far out to get them far enough out of the water and I feel like it is hurting performance. Where is the best place to hook the hoist up to to lift the motors. 2001 Promax 300x

Second, I want to change the impeller on my Sportmaster lower units, I believe they are also 2001 and am not sure of any serial or model number or what ratio they are if it matters. Does anyone have a part number for the impeller? Also, is there any difference in dropping these vs a standard drive?
Thanks in advance.
