Vintage Outboard Paint has the original factory matching colors for your motor, but it’s not exactly “inexpensive”. You could always go with something like Rustoleum or Dupli-Color but they won’t have the exact matching colors. If you’re matching the boat colors, you could also check with some automotive paint sellers.
