Pretty tight to get in there. IF you did and got a cramp, it would take the jaws of life to get you out :^) I had a charlie horse cramp while trying to get at our water maker. One of the most painful three or four minutes I've had on a boat.

Having said that, you might just be able to do it.

Can you curl 90 pounds with your left arm while bent over a saw horse with your feet off the floor?
