WHAT A GREAT FORUM!!<br /> I have been reading for a couple months and this has been very informative to me! I have been GIVEN!! a 15-1/2' Thunderhawke ski boat if I would "get rid of it" just to get the '71 E'rude Ski Twin 40 horse (Model #40153G). <br /> I have a '62 John. that has the generator on it that I would like to hook up in this boat but unclear what I need in the way of a volt. reg. or is it needed. Only had this for about 2 wks. and have not ordered a manual yet but will. <br /> Any help or comments, which I know I will get, will be appreciated. GOT TO LOVE THAT RIVER!
