I replaced the Martec 2 blade 17 - 10 on my Vision 32 with a 16 -3 blade Max prop. (Yanmar 3GM - 30F with 2.61 reduction). I kept the 10" pitch but am still "underpropped". I am going to change this to 11" or 12" pitch and would like to get it correct the first time I lift out. Has anyone tried this? If so, what is the best pitch to use?
