mounting height dimension, if maximum speed is the only
objective.
d - This line may be preferred to determine outboard
mounting height dimension for dual outboard installation.
e - Outboard mounting height (height of outboard mounting
brackets from bottom of boat transom). For heights over

operation is usually preferred.
