I would replace it all, it has two bad spot in the middle but the rest doesn't look great. Yes the furniture is plywood based and all in good shape still. I'm not sure of the hours on the motor but I have had it apart as when I bought it it wasn't running. If I had to guess I would say about 200-300 or so hours. I have done a full service on the lower unit also. Located in lake Elsinore
Thanks
