hello all, new to the site and looking for ANY advise. My dad left me his 84 17' charger foxfire that has been sitting up for years. to my suprise the 150 evinrude fired right up but after looking at other posts decided to look little deeper into the boat. removed the aluminum cap over transom and descovered the wood rotten under glass. how hard is it to remove the top cap and is it possible to do it right but learn as i go? i have minimal knowledge in boat resto. Thank You
