This is a great Mercury Sport Jet Crank Shaft for all the V-6 175 hp 210 Carb and 240 EFI  units, has the provision for oil injection gear (not included). Exceptional condition, no issues at all will provide the same service as new.

The Sport Jet cranks have a different spline configuration for the driveshaft, so an outboard crank will not work.

This unit has never been in salt water, all surfaces great!
