I have a 2009 Yamaha F250BTXR motor and I am going to replace the water pump impeller. Done this before on many other motors but I have a procedure question. Rather than leave the shift in Neutral for the procedure I was thinking that I should put it in Forward or Reverse before beginning. My thinking is that if the driveshaft splines do not line up exactly I can turn the prop to move the driveshaft to line them up. If I was in neutral turning the prop will not move the driveshaft. Is this a good idea or is there something I am missing??? Thanks
