Uneven fuel consumption

[bush]

Hi,
420hrs on 1999 350 mags. Just finishing up our first real trip on our 3000scr.. My port engine has been burning a noticible amount more than the starboard. My last fill, the port engine took 51 gal and the starboard took 41. They were both full to start. I've checked the flame arrestor and it looks clean. The oil pressure has creeped up a bit too. Starboard is rock solid at 40 psi @3400 rpm, the port is almost 60. Oil is full on both. Fuel consumption difference was noticed before the oil pressure.

Words of wisdom appreciated.

Thanks
Bush

Are the engines fuel injected or carb?

Either way the port engine may be running rich. If fuel injected the computer can be checked for parameters to may identify a richer than normal setting.

Hi. They are both fuel injected.

Though so since you said they are mags.

Do you have a genny and was it on? If so it may use the port tank which is why more gas was used from that tank.
