I am in the process of getting "cruel mistress II" ready for this winter. I am working on a "redrive" system for the propeller. I am trying to slow the propeller speed down to half of the engine speed. I have discussed different options with various friends and came up with a plan to use some automotive parts to build a reduction system. I am in the final phase of installing the reducer and am anxious to see if my design will work. It all looks good going together, but looking good and working good are two different things. I will put a photo on if it works. Joe
