Is there any way of draining gas out of an internal gas tank besides siphening it out with a hose??

what I do is break the connection just before it enters my outboard, and using a 5 gallon can, stick the fuel line down the spout of the gas can. A few pumps, and the flow starts. Takes maybe 8 minutes or so to get 5 gallons out. FWI, I put a shop light behind the plastic gas can, so I can clearly see the rising level, and stop the flow when I need to.

If this doesn't make any sense, I can post pics later.

Use the bulb to start the flow to a lower tank--should work just fine.

Fishing:
When I want to get the gas out of my internal tank, I blow it out with compressed air.

I disconnect the main line from the fuel tank - i.e. I disconnect the line containing the prime bulb from the tank and attach as large a line as will fit tightly on the tank outlet.

Then, I plug the tank vent with a hand.
Theh, I use a compressed air hose and air nozzle wrapped with a rag to seal the tank fill hole.
Then, as needed, I will modulate the air nozzle to put slight air pressure into the fuel tank. By deference, this will force fuel up and out of the hose into a fuel can. I am essentially syphoning out the gas, but I am using a slight air pressure to get it out in about 1/4 the time of a straight syphon.

Another thing that many folks use is an ordinary 12 volt fuel pump.
They simply attach a 12 volt fuel pump to the line coming from the tank, and turn on the pump and pump until the tank is dry.

Again, a very quick and easy method to drain the tank.

With all of these methods, you normally want the bow of the boat slightly elevated so that the typical fuel pick up tube is submerged in fuel for as long as possible to drain out the maximum amount of fuel.

Good luck

I think the primer bulb method is the easiest. You already have all the necessary equipment onboard.
