The Sea Devil is an awsome looking boat. Hudge ****pit, 6'4" headroom in cabin, deep vee and lots of storage. The downside is that I read that it has a balsa wood core hull that is subject to rot. I posted a similar inquiry as yours on www.thehulltruth.com and the replies indicated serious concerns concerning the balsa wood hull. Apparently it could become saturated and created huge problems, such as flexing and can be punctured if you hit an obstruction. As far as the engine goes, I always thought that when you buy used you must assume repower.
Good luck
