Old gas in boat

[tournyangler]

My boat has been setting up for several months with gas in the tank.  The storage was unplanned so I did not have any fuel preservative in the gas. 

I drained the tank, but is there a way to drain the carbs?  I want to avoid running it with old gas so the jets will not get clogged with gunk?

Anybody experienced with this problem?

What kind of motor.  With most you can remove the mains access screw and drain them.  Just depends on the type motor as to how hard they are to get to.  After removing them, you can pump the primer bulb and purge all the old gas out of the lines and pump.

chances are that if there is old gas in the carbs.......they'll need to be rebuilt any way.  You haven't drawn bad gas up the line...throw five gallons of gas in the tank and trailer the boat down a dirt road for a few miles.  This will slosh the gas around and help clean out the tank.  Siphon the gas out through the squeeze ball fuel line.  After that throw away the line and the squeeze ball.  Get a new one and a new fuel filter.  Crank her up and see what happens

How long is a few months and what kind of motor?  If it is Yam or SlowMC you WILL have to clean the carbs out.  If it is a Merc you should be able to drain the bowls as stated above, put some fresh gas in the tank, pump the bulb until fresh gas comes out of the bowls (be careful because you will make a mess and have gas everywhere) and I would also, once the system is reprimed, f the motor is carbed I'd premix the fuel 50:1 until I verified the oil injection system is still functioning correctly.

If the motor will start and run, put some StaBil in in some fresh gas and run the motor on the water or in the yard with plenty of water flush. It's not a good idea to run a motor dry or store it that way, as seals will dry out and cause mega problems later. Leave some of that treated gas in the tank over winter. It also a good idea to run the motor at least once a month to keep the water pump in good condition. Around here we see WAY too many boats started up in the early summer, even new motors showing bad water pumps.

Thanks guys!  I will clean out the gas in the line and primer bulb, change the filter, drain & clean the carbs, and see what happens.
BTY, it is an old '90 Johnson GT150.
