i have a 2000 mercury 5hp 2 stroke engine. and i was wondering what the fuel-oil mixture ratio would be?

thanks.

50:1

ok thanks.

Just to confirm, Raul is correct on the mixture - 50:1.

Just to clear up, the outboard may "old" in years model but it may be brand new ( no use at all ) when such is the case then the mix ratio should be 25:1 for the first full tank ( break in ), after that 50:1
