Hey guys i agree with big shrimpin.. I ran my twenty for two years with original transom and a 2003 honda fourstroke 225 Bolted right to transom with a Plate and a ton of 5200.
Its a 73 19'6 Some days you get the Oh sh*#($ where did that wave come from and have to do some serious manuevers to get back in on big days and not your typical south florida four foot slop... That damn transom would literally flex, and i dont mean wobble it would rubberband. they can take some serious abuse which im sure everyone knows.
Money was tight when I re made my transom so I added One sheet marine grade on outside and added two layers of marine grade over inside of old transom Now its about 5 1/2 inches thick.
Not to mention biaxil and resin. Now I have merc 250 w/bracket on it. Older model
My neighbor also has a twenty 1969 and he used regular plywood.. <original owner> Transom is dry <no rot> I dont recommend it but hey it worked and he has a 175 straigt to transom.
Best of luck
