Dripless Shaft Seal


The stuffing box is difficult to reach and inconvenient to repack or retighten. This has lead manufacturers to create a mechanical seal that keeps the water out while allowing the prop shaft to rotate. Many people have installed these, and mostly they love them.

I've got my reservations, as a failure on one of these devices may be sudden and catastropic. I prefer to use a high-tech packing material (along with standard flax) to give me a no-drip stuffing box that fails slowly and gracefully.

I'll leave it to a fan of these mechanical seals to write a description of these units and their advantages. Also see Dripless Shaft Seals Have Advantages by Terry Johnson for a good description of these seals, and some of their advantages and disadvantages.


Cruising the Chesapeake: A Gunkholer's Guide cover Cruising the Chesapeake: A Gunkholer's Guide

My favorite Chesapeake Bay guidebook. While it mentions marinas, it concentrates on anchorages—the kind of places I prefer to spend my time. And in addition to listing shore facilities, it rates each location for Beauty/Interest and Protection. This is the guide you need to really cruise the Chesapeake Bay—a smorgasbord of small creeks and coves.
