Petrol left in tank
I have a 4.88 Quintrex seabreeze with a 2 stroke 60HP Johnson, I recently was on holiday and went out in the boat every day for 6 days, before I left home I put 50 litres of Premium ULP in the tank, after the 6 days I had just over half a tank left, and it is still in the tank. The motor is oil injected from a tank in the stern, so there is no oil mixed with the fuel in the tank, what i would like to know is how long will the fuel in the tank last if I don't use it for a while? Only having external tanks in the past, I am not sure about under floor tanks.
Thanks guys. Mal.
