Oil Seal 833996 18-2044 Volvo Penta Stern Drive Gearcase Shaft Seal Pack of 2
Oil Seal 833996 18-2044 Volvo Penta Stern Drive Gearcase Shaft Seal Pack of 2
Product Overview
Volvo Penta oil seal 833996, sold as a pack of two in a 150 x 180 x 10 mm bag at 14 g. It fits stern drive and shaft applications calling for 833996, and the same seal is sold under Sierra number 18-2044.
Volvo Penta numbers its seals by the bore and shaft size it was designed for, so the number on the old seal is the number to order. Sierra 18-2044 crosses straight to it, which makes the seal easy to find even where Volvo stock is not carried.
Two seals in the bag means one to fit and one to keep. Seals are the cheapest part in the drive and the most expensive to ignore, because water past a lip takes the bearings with it.
