Jake, Thats pretty simple! Look at the bottom of the fuel tank, you'll see 4 holes plugs with a rubbery looking white colored thing. These are the motor mount legs that hold them in place by press fit. Grasp the motor an wiggle from side to side, while pulling and it should come loose! DO NOT yank or pull hard as it will rip those legs off the mount and you'll have to replace it! Or even both the motor mounts! IF it doesn't let go by wiggling and pulling at the same time, take a screw driver, one small enough to slip through the holes in the fuel tank, and push on the legs of the mount. Don't push hard being the screw driver will cut into the leg of the mount, but hard enough to get the mount leg to push up into the fuel tank, but not come completely loose being you can drop the whole works like that and then, once all 4 legs are loose, then grasp the motor an pull lightly an it should come loose in your hand.... HTH
