Marlin Fuel Filler Main vs Aux

[hinmo]

My labels are worn off my fuel fills. Is the fwd fuel filler the main and the aft most one the aux?
One would think I could monitor the Yamaha fuel gauge as I add fuel to one at a time, but the gauges seem erratic.

thanks

On my 97 Marlin the forward fill is the main

I have a 2007 and the Main tank is the forward and the Aux is the aft also.

same as 265..main fwd, aux aft.

When switching the Yamaha LCD gauge you have to wait a while before it reads correctly.


Question for everyone- Do you run Aux down to empty first then Main or vice versa?

I just did some experimenting on long runs and it seems that, from both full, running Aux first to near empty then switching to Main gives a better ride.
What are your thoughts?

That is the orientation on the 2011 305 Express and seems logical.

I have the weight of aft generator. On long runs I generally have the aft box loaded with a lot of ice, so tend to be a bit stern heavy. I do find burning off the aft tank first results in improved running angle.

I run the Aux tank down first because I'm stern heavy and for the reason you mentioned.
