67 TO-BE Outboard Marine Engine with Turbo Head Button. Requires a 67 90 degree exhaust header, 67 Outboard Tuned Pipe, and lower unit (in stock). This engine will fit any commercially available lower unit that would mount the older K&B Outboard Powerhead. The mounting holes simply need to be drilled out to accept the feed through mounting screws that thread into the NR 67 PTO mounting place. This includes K&B (in stock), Hyper Performance, Lawless, and others.
