Dripless Shaft Seal Installation

We began our trip moving the boat from Anacortes to Kenmore. The first step, though, was to take the boat out for some upgrades. We motored from Cap Sante Marina to Skyline Marine Center on the other side of the peninsula. It's only about 4 miles on land, but about 12 nm by sea. It took us about two hours. We backed into a dock using our new docking skills, then got hauled our and placed on the hard at their DYI yard. There, Fathom Marine installed our new dripless shaft seal.

Boats of this generation come with a packing gland. This is the material that keeps water coming into the boat around the propeller shaft where it enters the boat. Except a packing gland has to let some water into the boat, because it also acts as the lubricant, keeping the shaft from overheating. This puts a constant amount of water in the bilge. This means the boat always has moisture in it, which leads to mildew and other problems if not controlled. A dripless shaft seal uses a different mechanism for lubrication, meaning that no water needs to enter the boat from the shaft. They are not terribly expensive, but there is the labor and the boat must be hauled out.


While doing our docking training, we noticed the transmission was having quite a bit of trouble going into gear. Eventually, we discovered that the idle was set too low for our Perkins engine. The correct idle was buried in the Perkins manual. When bumped up to 1000 RPM everything worked just fine. This is faster than most engines, but the transmission just does not work at a slower idle.

Adding our new boat logos

While the boat was hauled out, we took the opportunity to lubricate all of the thru-hole valves. We also removed the remaining boat name, home port, and Washington State ID number. Our boat is Coast Guard Documented now, so should no longer have those numbers on the bow. We then added the new boat name and home port.

The boat was then dropped back in the water. We took advantage of our reciprocal moorage with Flounder Bay Yacht Club to stay there at Skyline for two nights, while we got all our ducks in a row for the voyage south.
