i bought a 1968 holmes horizon flatty and im getting ready to start to rebuild this year. transom was shot and electrial was bad. i cut the top off the back and the transom and floor have been removed. think of hanging a 175 mercury on it unless someone has a better idea. i need some input on the floor and transom replacement. i think it had 1/2 wood on the floor, no stingers as this is a flatty. so any help or input would be great. feel free to im me or email. thank you
