Before taking the measurement, we have to remove the rope guard

first.Also to make sure weather the vessel have the poker gauge or

not.This poker gauge is use to measure the propeller shaft drop

(known as propeller wear down). After dismantling the rope guard,

make sure to turn the blade to one position refer to the

marking.Normally, we take top measurement and bottom
