Hello,
I'm new here, relatively new to bigger boats, and not a mechanic. The starboard engine on my boat is using more gas than the port engine, which is causing the boat to list to port. Starting with two full tanks late last year, the port tank is nearly 3/4 full whereas the starboard tank is just over 1/2 full. Both engines seem to run normally. There is no crossover valve to allow gas to flow from one tank to the other; each tank feeds the engine on the same side.
What are the most likely causes for the difference in how the two engines are using gas? I'm hoping it's an easy adjustment or fix.
