Older 9.9 gas from main tank?

[Finlander]

I have a Lund 1775 Pro-V with a 150 Johnson.
I am going to mount my 9.9 Johnson on the boat and would like to hook up a gas line from the main tank rather than having a portable sitting in the rear.
Any suggestions?

If your 9.9 is a 2 stroke, you have to use the can unless you have oil injection somehow.

If the kicker is a 4-stroke:
3 way shut off valve spiced into the main gas line to the main motor. That's what what I did. Any boat dealer can find this part in their big parts catalog.

Purchased a new 3 gallon tank and fittings.
Put in oil and gas, took the hose and stuck a small nail so I could pump out the old gas from the hose.
The old gas in the hose was brown in color and looked pretty varnished.
Hooked it up too the motor, gave it a few pumps, then pulled out the choke and after 10 or so pulls it started and ran like a top.
No sputtering, just purring like a cat!
This will definetly be cheaper to troll with rather then the 150!
