Been in the market for another boat and have found a Glastron that I really like. Its a steal but the only problem is there is a hairline crack about an inch long in the transom. I don't know a whole lot about these repairs but I was wondering if it was worth it to buy a boat like this and fix it yourself? I don't think its worth a full transom replacement but I have heard of  attaching thick aluminum or stainless steel plates and bolting them in. Any opinions on this or is it not worth my trouble?

Find another boat  

That's what I was thinkin. Thanks  

Depends on if it's a real CRACK or if it's just a stress crack. Stress cracks are on both sides of the transome in most glass boat and don't hurt a thing. Opened up cracks are not suppose to be there though.

I first check a transome buy triming the motor up, then stand or have someone stand on the mid section nead the lower unit and bounce up and down while I watch the transome for any movement, there should be NONE, (and I weigh 215 pounds). If there is, the only thing I do after that is get back in my vehicle and leave.

The only way to properly fix a transome is to replace it, very expensive to have it done and very difficult to do yourself.  All those other "patches" may do nothing but cause you to loose a motor and sink a boat.
