"the 71 wont handle the horse power of a 440,,, dont even try,,, check bw specs,,,, has halve as many plates ,, tedc"
 
can the 71c be up dated to han

can the 71c be up dated to handle it. Its not a speed boat never will be just wanting to keep same shaft and props thx ray
 
will be identical torque going

will be identical torque going through the box if you are re using the prop .in reality that would be silly cause you would have a heavier boat running the same prop at less revs .boat may loose speed maby loose economy .you must upgrage the box and prop to use the extra torque.
