twin engine fuel burn from side to side.
 

hope this doesn't sound like a dumb question but you guys with twin engines does both of your motors burn about the same amount of gas or does one burn more than the other?

I have only one 165 gallon tank. You have two seperate fuel tanks?

Mine run about a gallon apart at fill up after 75+ gallons burnt out of each tank. It started getting further offset one year, 5 gallon difference, so I cleaned the injectors and it went back to the normal difference. A difference can also be caused by the station pumps.

My starboard burns much more fuel than port. My friend with the same engines, same boat has the same exact problem. Just figured it was normal? I rarely fill up cause I don't like my fuel to sit, but last year I started full, added what I thought I needed for each weekend, and didn't fill again until August for a poker run. By then my starboard took 40 more gallons that port. Gas gauges are useless in my boat.

My Bullet has separate tanks. Not all that uncommon.

I have 2 tanks. One of my engines uses about 5% more fuel. It could be that it is the one I almost always start first.

yes.two tanks.79gal a side.my port motor burns about 5-8gal more than starboard.first twin engine boat I have owned.i can say this.the port drive is harder to turn than the starboard.the transmission is tighter on that side.a noticeable difference from side to side.but all the transmission guys say this has nothing to do with why the port burns more?wtf

Mine is exactly the same (with 575's). Starboard is thirsty. I always use starboard around docking situations though.

I run them both always, and use the shifting with engines at idle to dock. I've burnt $1700 in fuel so far this year, right now the starboard is on e and the port reads 1/3 tank. Going to do an offset fueling tomorrow for the weekend. 300 in starboard and 200 in port lol.

Thinking that if we ran the props spinning the other way port would use more?

that's what I wonder also.in my case,trs,the only way I think could reverse rotation would be to switch the drivers from side to side.?

Both of mine are running, but I typically only have starboard in gear. ...which creates more load on that engine, thus more fuel burn. That's how I'm justifying it anyway. LOL
