Have recently purchased an 85 Sylvan 16 ft <br />Model 16 SMA<br /><br />I was mounting a transducer on the transom and noticed that the lower 4 inches or so of that transom appears to be filled with foam. If it isn't, and it is a wood transom, I have some serious transom rot as I can poke a coat hanger in the screw holes quite a ways. It looks like (viewing the rivet pattern) that it could be a combination of wood, aluminumn and foam.<br /><br />Can anyone tell me for sure?<br /><br />TIA
