Thank you!

If using retardant the SG is slightly heavier than water. A Fireboss normally doesn't usually carry a full load either from the water or off land, the floats are a significant dint in performance compared to a wheeled 802. Fuel load is 1400 litres plus a 3000L hopper load, the empty weight for a wheeled 802 is around 3000 kg. The only information I could find about the weight of floats is 1000 kg, that seems light  as the amphib gear is pretty solid. So just allowing for the weight of the floats the load of a Fireboss would be 2/3 of the wheeled 802. Most new 8's now are fitted with the F version of the PT6-67 which is rated at 1700 SHP, they do go well 😜

Marty got it right. With water, Kg to Litres is really easy. Additives and temperature change it marginally. US gallons are a bit of a trap in the system. IF you are buying Aero engine oil from the USA allow for the reduced Qty in your value comparison. Nev
