From memory, the ABYC standards for 250 HP specify 2.25" totalHi Jacques,
Sorry to bother you again but after reading building notes again I think I made a mayor mistake with the transom, thing is I used 3 layers of plywood without the clamping board now I see in the notes I need 5 layers (I always thought that was about the glass) please tell me if I made a mistake and please advice me what to do
Thank's in advance
thickness (57 mm), I prefer a little more.
Most of that thickness should come from the plywood core.
Look at the nesting drawing: you have 3 layers for the transom plus 2
for the clamping board. This means 5*12= 60 mm plus glass at the motor
What do you have?
PS: I prefer to discuss this on the message board, others will learn
