Lets say twin step monohull 8,5 metre long around 2400 kg
Outboard engines, shafts around 75cm apart
Just teoretical. Do I measure center of drive shaft from the lowest point of the bottom in place where the engine is mounted ??

i would start with drive shaft level with the part off the hull it lines up with.
(the steps in hull could make a differance, it would be worth talking to cookie)
