when I turned the blue rubber key shaped screw to let the water out of the engine last winter, it broke. water came out because it had a small hole within it. I don't know how to get the rest of the rubber out of the engine. thanx

Ayuh,.... Donno exactly which fittin' yer talkin' 'bout, but basically, ya remove the fittin' the blue plug is stuck in, 'n use an easy-out or drill or whatever it takes to get the broken plastic out,....

If it's a metal fittin', heat can be used,....

It's the drain plug on the side of the engine. I can order a new one but I don't know how to get the rest of the rubber plug that is left in the engine out. I don't think I want to take the fitting out, The rest of the rubber drain plug would normally turn out like a screw but the top the turns it broke.
