Newbie here so trying to learn and thank you for accepting me. I have an old possible sears 12’ aluminum boat I am trying to bring back to life. Only stamped number I found while sanding the transom outside. S-544 54 is what I see. Any guidance on how to find out information on what I am actually trying to bring back to life would greatly be appreciated!! I feel I should not have to pay to obtain this and again thank you for accepting me!!! Looking forward to take in all knowledge you can offer!! Great group
