Okay folks,
the school is coming to a close and for those whom are going to try to tube load your weapons for the first time, ya might want to take a look at this.. The link will tell you just about everything that you need to know about how to boresight yours.
These school of the boats are no longer about asking for information but me giving as much information as I can before the school is closed
Good luck to those whom have stayed with this from the begining and learned and been able to use this information on your own boat
