Re: new old stock 2009 merc 4 stroke 30hp - anything to be aware of?
Couple of things to be aware of. I don't know which model merc you are looking at, but the older NOS motors are sometimes carburetted motors, versus a newer EFI (electronic fuel injection) model. The dealers had trouble selling them as the carburetted models were being phased out becuase for just a little extra cash, you could get a much better motor (EFI). If the motor you are looking at is a carburetted motor, then comparing the price on the NOS with a new 30hp fuel injected model will be comparing apples to oranges.
If it is new old stock, it should still come with a warranty.
