Seeing all the threads on rebuilding transoms, it got me wondering; how do you know when its time to do this? I only run a trolling motor on mine, but would eventually like to get a little gas motor to go with it. The wood is definitely old and looking pretty rough. Its far from rotted away though. Is this something I should look at getting out of the way now, or wait and focus my attentions on other projects first? Thanks from a newb.
