to get my tristar on i too back the trailer in way deep and float it on and hook up the bar .
then i need my wife to sit in the boat and center it on the trailer while i pull it out slowly so she can hold it centered. if i don't back it in deep enough my front eyelet will catch on the v block up front also when she slides off the trailer. i just prefer to float it on anyways .don't need to wack the prop.
1988 mastercraft tristar (open bow).
