I'm trying to remove a reducing bushing on the return side and I can't take it out .

The bushing is reduced to 1.25 inches . I'm trying to change it to 1.5 inch bushing.

What negative impact would there be if I use a close nipple out of the 1.25 inch and increase it to 1.5 inch using a 1.25 to 1.5 inch coupling ?

    Very little difference. And a lot less risky than trying to dislodge a pesky bushing…

    if the output of that boiler is about 80,000 btu/hr you need about 8 gpm to move the output of the boiler. 1" could do that. so unless there is some reason you are moving a whole lot more water than you need to, 1.25" is perfectly adequate.
