[md_sailor]

Can anyone help me out with the Correct Gap setting for my '89 150? NKG plugs?

Probably about .036", give or take a couple.

RPM's

Boats.net it appears you are the Oracle here. What is the Max RPM for my motor? 1989 150 ETXF? Can you recommend the best Yamaha or other brand Prop for the motor? Its mounted on a 18 Outrage. I was thinking a Yamaha Reliance or Saltwater Series 2 Prop? the Current prop is stamped 19M? Know what it is? Thanks in advance.

The rpm range is 4500-5500 rpm's, you have a 19 pitch prop on it now. The Saltwater Series prop works well on the Outrage boat.
