i have a 1985 aq125b w/270 outdrive. to order a new prop i need to know the shaft length..how would you measure the length of the shaft. mine has two sets of numbers, one is a part# a16142, the other the prop info i guess, 14r19mwc,, thanks kc
The "14r19mwc" on your prop indicates that is is a Michigan Wheel Corporation (manufacturer), 14" diameter and 19" pitch, right hand rotation. "a16142" is likely the article number.
