What's the best way to remove leftover gas at the end of the season?
Thanks

Presuming the boat is out of the water, you can remove the fuel line from the engine side of the squeeze primer bulb, add a length of hose to it down to a fuel container on the ground. You can route thru the open drain plug on the hull, use the primer to set up a siphon action. Not all the fuel will be drained since the pickup is off the bottom an inch or so.
Raise the bow to get the most out.

If you use ethanol and if gas color is normal looking per each batch, I'd burn it in the auto over the off season.

Curious to why draining at end of season? I just fill mine up, add Startron and ready to go in the spring. Using Ethanol also and not had any issues so far. I think if you don't experience any water issues currently, it would be ok. If boat is covered and not going through rapid heat/cool cycles from sun then condensation should be minimal and what little would happen, the Startron takes care of it.

4th season on this principle and no issues.

Every time I have drained old fuel, I have pulled the level sender through an access plate and inserted some clear poly tubing to the bottom corner of the tank. Attached a primer bulb to the end of the tubing and pump away. I usually use alternate with 2 or more 5 gallon containers. Just did this with the 92 244 Explorer I picked up, as I was uncertain of the age of the 80 gallons of fuel left in it. Used it in my vehicles without an issue.

In my experience, I have been unable to get a nice solid siphon through the existing fuel connections.

If this works you either don't have an anti-siphon valve or it is bad.

A recent article in Boating Magazine now recommends an empty tank over a full one for storage. Since it is hard to really run the tank dry, I leave about 20 gal in the tank treated. In the past 8 years doing this, I have never had an issue.
Should the gas go bad, i would rather have 20 gals of bad as opposed to 80 or more:)

Seasick is correct. Boat from factory will have an anti-gravity valve installed on elbow off of the fuel tank, that will not allow gravity siphoning the fuel. Options include, 1. temporarily replace anti-gravity valve with straight through barb, and then siphon out fuel, returning anti-siphon valve when complete, 2. use an APPROVED FOR FUEL type manual or electrical pump.

Thanks guys
will go with siphoning out thru the larger fill inlet as I've also had limited success with the small fuel hose/primer bulb option. Don't want to leave pre-mixed fuel for spring (1984 Johnson 185- VRO was bypassed).
