Engine gas consumption
I recently owned my fathers boat and i have a question. Is there a way to calculate the gas i need when i wanna go fishing or a small trip? Im new to all this and im looking for how much litre per hour for example the boat engine is consuming.
The boat is a 13.8 feet (4.2 meters) inflatable boat with a Johnson 40 (2000 model, BJ40PLSSM) and im running it in seawater.
Thanks in advance.
