On sailing a Folksong: an engine anode

I’m not an engine man, preferring to sail and enjoy the vagaries of wind and sea to the precision of  metal parts and fuel consumption.

On the other hand, I know the relief of the engine starting first time and the expectation of being back on the mooring in time for tea.

I look on it as a useful friend which will get me out of trouble if I really need it.

I keep it clean,  can change the oil and oil filter, and know more or less what this part or that part does – but have no overall grasp of it. In fact, I consider it a bit of a challenge.

So, realising that it was time for a proper service, I got the engineer from the Yanmar dealer in and watched him work. (It’s a Yanmar GM10)

A pleasure to see a job done well.

As you would expect – he worked methodically, step-by-step through the process.

And I recognised most of what he was doing, even if some of the bits were not quite where I thought they were.

But when he unbolted the alternator and moved it out the way, I knew I had done the right thing.

What was behind there? Well, the anode of course.

OK . . . . . so I didn’t know there was an anode in the engine. Makes perfect sense. Of course there is. Different metals sitting together in a wet environment.

This is what it looked like.

All you need to know is that a new one is over twice the size of this and a rather elegant dome shape.

I guess it hadn’t been changed for a long time – certainly in the time I have owned the boat.

Anyway, I’ve learned the lesson – and won’t forget it.

  1. Bill – good advice change it every year those GM10’s can suffer corrosion – one of the few problems with an otherwise good engine.
