Am I thinking right here? Current hull let's say runs 97 with 1.48: 1 drives with 32P wheels at 5000, engine output torque 850#' at 5000, and 15% slip. If I went to diesel and wanted to run 97, say at gov rpm of 2800/850 torque available, looks like I would need a .85:1 overdrive, with perhaps a 33 pitch wheel? Can I assume hull needs net 850 #' to run 97? Now what happens with the torque avail at prop when you go from a 1.48 to a .85 ratio? Is the 1.48 torque really like 1258 going into the drive and the overdrive 723?
