transom question

when i climbed into my boat today i noticed something that concerns me. i keep my motor tilted all the way up and use the lower unit as a step. when i stepped onto it i noticed a little give in the transom. so i jumped up and down on it and it was definantly moving. total sway at the top of the transom was probably about an inch or so. maybe a little less. is this something to be concerned about? is thier a way to test my transom?

it would be just my luck for it to be shot. i am/was rolling paint in the morning and am planning on putting this thing together this week. i have purchased a lot of goodies for this thing in the past few months and thier is no cash left for an expensive transom repair.

boat is a 92 cuddy w/ johnson 175. tx in advance
