    So my boat is a Pearson 390… Sort of the redheaded stepchild of the 424. I’m working on the powertrain of this new to me boat and I need to figure out the old Perkins 4.108, what sort of Borg Warner Velvet Drive gear ratio the transmission would carry. I’m assuming it’s 1:1 ratio? The engine, rather noisily, purrs like a kitten … However very recently the transmission seized and I have ordered a new 71c velvet Drive with the 1:1 ratio. Am beginning to second-guess my choice of gear ratio any help?

    Does it have a v-drive? I believe that the 424s have 1:1 transmissions but a reduction gear in the v-drive.
