While some of the items on Madrone’s project list are big jobs, there are also plenty of small ones.  The problem with boats is that it’s very easy for the latter to turn into the former.

Removing the windlass motor and gearbox requires Mike to wiggle up into the anchor locker and try really really hard not to drop any of the windlass parts on his head

A perfect recent example was changing the oil and lubing the anchor windlass.  Typically a pretty simple job, it’s a task we’ve done in the past in an hour or so with nothing more than a screwdriver, a wrench, and a few towels.  The abovedeck portion of the windlass is stripped down, and then the belowdeck oil-filled gearbox is removed so that the old oil can be drained and then replaced.

It was obvious right away that something was very wrong when we found this slurry of yuck and some scoring on the shaft

Just like every other time, the abovedeck work went smoothly – it’s a job we do once a year and we’ve gotten fairly efficient when working on it.  But when we removed the belowdeck gearbox, it was clear that all was not well. 

After deciding we needed to replace the windlass Mike got to work removing the old one.  Many hours later he was victorious!

The oil smelled bad – like rotten fish – and it was clear that some seawater had managed to find its way past the shaft seal into the oil reservoir.  When we investigated further, it was easy to understand why.  Some sand and debris that inevitably gets pulled up along with our anchor had clogged the holes that are designed to let seawater and other anchoring debris drain out of the windlass body.

After the epoxy dried we drilled new holes which have sealed edges

The clogged drain holes resulted in a slurry of sand and salty water sitting between the dissimilar metals of the stainless windlass shaft and the aluminum gearbox housing, which over time created a huge amount of corrosion.  This corrosion got bad enough to eat away at the smooth area where the shaft seal sits, which allowed salty silt into the gearbox, which ended up both scoring the shaft and contaminating the gear oil. 

We pushed straws through the center of each bolt hole after they were filled with uncured epoxy so we would have a center pilot hole when drilling the new holes

The windlass was installed 25 years ago, so of course repair parts are no longer available. And since it’s a mission-critical piece of gear for the type of cruising we enjoy, it was a fairly easy choice to replace it with a new one.

While the decision was easy, the implementation, predictably, was not.  The windlass was bedded to the deck with sealant and adhesive that is intended to be permanent. Removing the windlass base (lots of grunting and cursing), scraping off the old sealant (even more cursing), and then sealing and re-drilling the mounting holes took several days of nonstop effort.  The actual mounting and sealing of the new windlass to the deck was easy, and only took about an hour.

We’re happy to have a new windlass since we rely on it.  And the project was a perfect example of how easy it is for a one hour job to turn into twenty.

Back in action with a shiny new windlass!
