Sierra-Tube-Exhaust from SIERRA
Some larger V-8 engines that create a large amount of back pressure use exhaust tubes rather than bellows. This helps to relieve the excessive pressure and eliminate problems with premature bellows failure. In the past, the exhaust bellows would blow up like a balloon and cause the drive shaft bellows to rub against the yoke and U-joints causing holes in the bellows.

Adjustable Packing Nut Wrench from SEAFIT
Better than a pipe wrench If you are not equipped with wrenches that fit the nuts on your stuffing box, we suggest you purchase TWO of these. Why? Because you will need two to make an adjustment: One for the locking nut and one for the adjusting nut. These wrenches tend to be easier to use than pipe wrenches—especially in tight engine spaces where many boaters must work. Primary Usage: Adjust/remove inboard shaft packing nut . Size: 1" to 3" adjustable .
