i have just recently purchased a 1977 23 ft. sleekcraft daycruiser with a 460 with a jacuzzi 12yj pump, need some feed back on the pump, took it out yesterday to el cap and the boat seem to be capatating, i was doing research on the pump last night and from what i found is that it seems to be normal for the pump to do that. to get the boat to plane i had to have it around 4500 rpms. is there and inexpensive fixes for this? i saw the energizer kit for this pump but it runs $2000.00 (i paid less for the boat), any other inexpensive ways, does anyone have a used kit? need some ideas. thanks
