Hi, does someone knows the thickness required for an aluminum transom to support the weight and pushes of a 200 HP engine without deforming ? I guessed 3/8" but i'm no engineer.

Any advice would be truly appreciated.


Not quite what you asked for - but to fix up a bass boat with a broken
transom for my son, I added a 1/2 ply false transom outside, and two
two by four cross-beams inside (bending in their weak dimension)
through which the engine was bolted.
This was to handle a 90 HP engine which it has done faithfully for
the following eight years,
