I have a 2007 225 VMAX HPDI and I recently had the prop reworked by Mark. When I go to tighten the castle nut to the torque spec of Yamaha the castle nut is covering the hole about 1/2 way. When I tighten the nut more so the groove aligns with the hole it is torqued almost double the specs. Is this ok or should I lossen it or put another SS washer under the castle nut to help with the alighnment?
