Transom core materials

[TUGBOAT]

I just redid My transom with "Poly Mac" 24# Density foam.It took a lot of research ? If You were to get hit in the Head with a piece of this(2x4) size You would fall before it would Break!
Heavy,Hard & closed cell.Works really easy.I was worried about compression @ motor mount.Thickened the fiber a lil'.Water cannot creep.I hope I made the right decision,I'll let Ya know in 20 yrs Ha Ha.Maybe the diff. in weight will give Me another 10 KNOTS !!!!!!!'83 MA
