Place Diverter Nozzle Inserts
Through years of research we found the 3-1/8" nozzle to be, by far, the most effective size for most jet boats with big block Chevy, Ford or Oldsmobile. In some cases, larger and heavier jet boats might require a little larger size 3-1/4". Your diverter must be machined for the inserts. Stock Place Diverters will not be machined for these inserts.
