2003 merc saltwater died & wont restart

[<Lyles Fishing Tips>]

Hi Folks, My newish merc 121 hrs and reently serviced by a dealer just died when coming in from the last trip.
The low oil sensor did go off just prior to the stopping. there is still about a third of the resivoir left so just thought it was the sloppy conditions we were in. the motor is not seized there is spark there is full. If the oil is low is there a protection built in?

I have an 04 merc 125, sensor will go off around a third full, but wont quit running,its just an alarm to me(hey dummy put some oil in here), like JB said squirt some gas in and see if it will start, basicly see if its getting gas, i know they have plastic wire ties instead of steel clamps on the gas lines, check them, i had one break the 2nd time out on my new boat,good luck
