We just tore down an old 12 degree racers casale and he broke the shifting dogs that put the boat into gear. I am told it is a splined collar with two studs or dogs on the face that engage the v-drive. Can anyone help out this struggling Nostalgia racer? He is the only small block racer with a 15foot Jones SK. Last test he broke a u-joint which blew up the alum shield, the time before that he killed his ignition, and the time before that he forgot to install the prop! Believe it or not, he is a veteran SS driver who is coming out of retirement! Will Andy sell just this one part? or does anyone have a parts box that they will separate for a worthy cause? Thank you guys for the help cause we want to see him make more than two laps!
