How to Check for rot ??

[twintrades]

Hey IM going to be buying a used boat. I dont have much and never will so anything over 1500 is outa the question. Im selling all of my outboards and prodject boats. Ect to get some money. Im handy at fixing things and mantaining the boat.

My question is how do i check a boat for rot and other problems without drilling and dissasembly.

What are common problems that i should check for ?

Im looking at I/O and outboard types to.
