WE COULDN'T HAVE SAID IT BETTER

“In addition to raising speeds across the board, the ProCharger gave our test boat [Rinker 243 Siesta v-bottom deck boat a quicker hole shot. The souped-up engine [stock 7.4 MPI with 5 psi Intercooled M-1 ProCharger] pushed to us 36 mph in 7.38 seconds, whereas the stock package took 10.28 seconds.”
