"i have a mercury 60hp 2003 outbard EFI, alarm goes off whilst driving at around 4500rpm, the oil pressure has been tested and ok, if i put it back into neutral for a few seconds and take off alarm will stop but if i take off quickly alarm will go and engine will seem to missfire until i select neutral for bout 5 seconds and go again, maybe will go for about 10miutes of driving and this will keep happening, i have had it into dealer they say it has 720 code errors in computer..which they told me cannot be cleared? and that they recommend replacing the fuel pump at $480au an replacing the computer at $1800au, which sounds very expensive. what would you suggest to do or try."
