Note: Underoor fuel tanks are often difcult to rell to
the same level twice, due to air pockets.
With underfloor fuel tanks:
Trim the boat to the same angle in the water each •
time you follow procedure A.
•
Mostly use procedure B below when adding fuel, but
completely ll the tank and follow procedure A about
every tenth time you add fuel.
B - Part ll a tank
When you part fill a tank
Write down how much fuel you add. Change the
number.
> Add fuel
On a multi-tank boat select the tank you have added
fuel to.
Note: If you follow procedure B every time you add fuel,
then a small error will accumulate, because it is hard to
measure exactly how much fuel you add. To avoid this,
completely ll the tank and follow procedure A about
every tenth time you add fuel.
C - Removing fuel
Before removing fuel
> Set remaining
On a multi-tank boat, select the tank that you are •
removing fuel from.
Write down the value of Remaining for the tank; this •
is the amount of fuel originally in the tank.
Remove fuel from the tank and write down how •
much fuel you remove.
Subtract the amount of fuel you removed from the •
amount of fuel originally in the tank to calculate the
amount of fuel now in the tank.
Change the number on the •
Set Remaining menu to
the amount of fuel that you calculated was now in
the tank >
Note: You can also use this procedure when you add fuel
to a tank. In this case, add the fuel you have added to
the amount of fuel originally in the tank to calculate the
amount of fuel now in the tank.
