Bad gas removal

I am having trouble removing the old gas (18 months with stabil at fill time) from my 2011 Lund 1675 impact.
I tried connecting a primer bulb to the disconnected gas line that goes to the engine.
It did not siphon anything out. Tried opening the gas filler cap, no difference.
Tried starting the engine, but I guess the fuel pump is in the engine (2012 90 hp 4 stroke Mercury).

Any suggestions?

Is there anything in any of the access panels in this boat that may facilitate gas removal?
I have an electric syphon available.

About how much gas in the tank. When I removed mine from by 2005 lund fisherman I had to crank up the front of the trailer to the top point so that the boat was angled enough for the gas to pickup. I just disconnected the line after the blub and it slowly trickeled out into a 5 gallon gas can.

Couldn’t you just disconnect the fuel line at the primer, secure a hose at the barb of the primer bulb, to either your siphon or a fuel pump, manually prime the siphon or pump with the primer bulb, then activate the siphon or pump?

That’s what I would do. It’ll suck the fuel out and just pump it into a bucket or fuel tank.

I’m sure you know but in case you don’t – make sure the siphon output is lower than the tank in the boat. Can’t siphon uphill !

you can if you have a electric siphon like he said he does though. can you put a hose down the tank fill hole?

I’ve drained a couple of on-board tanks using a hand fuel pump from Harbor Freight and just going in through the filler cap. Sure, it takes a while to pump out the tank, but I pumped over 20 gallons out of a speed boat tank once and it only took about half an hour, so it can be done.
