BIGFOOT GEAR HOUSING
Do not use lubricant on top of driveshaft. Excess lubricant, that is trapped in clear-
ance space, will not allow driveshaft to fully engage with crankshaft. Subsequently,
tightening the gear housing fasteners (while lubricant is on top of driveshaft) will
load the driveshaft/crankshaft and damage either or both the power head and gear
housing. Top of driveshaft is to be wiped free of lubricant.
6. Apply a light coat of Quicksilver 2-4-C w/Teflon onto driveshaft splines.
7. Apply a light coat of Quicksilver 2-4-C w/Teflon on gear case shift shaft splines and upper
shift shaft splines. Do not use lubricant on ends of shift shafts.
8. Install components as shown in appropriate photo.
