2005 Marlin 300 Fuel Select Valve Question

[fisheye1987]

My boat has two fuel select valves with main/off/aux options. One valve controls the fuel supply for each engine. One valve is slightly forward from the other. Which valve controls which engine? Thanks.

Unclear from the fuel schematic. I'd guess the furthest one is starboard. The closest to the transom is the port. You can trace them pretty easy.

I have the same question. I've been having problems with fuel separation but only in one tank?

If you turn the switch to 'off', which engine eventually dies out?
