CAUTION
Do not use lubricant on top of drive shaft. Excess
lubricant, that is trapped in clearance space, will
not allow drive shaft to fully engage with
crankshaft. Subsequently, tightening the gear
housing fasteners (while lubricant is on top of
drive shaft) will load the drive shaft/crankshaft
and damage either or both the power head and
gear housing. Top of drive shaft is to be wiped free
of lubricant.
6. Apply a light coat of Quicksilver 2-4-C w/Teflon
onto drive shaft splines.
7. Apply a light coat of Quicksilver 2-4-C w/Teflon on
