In preparation for more extensive cruising plans this season, I thought I'd give my 1GM a silver service. So far I've called it "sir", topped up the oil from the right and held the can at the base. It was a struggle using a fork and spoon instead of spanners though. Any suggestions for completing the job?

One should offer a Filtre de Huile comme graisse en caoutchouc as a starter,
The meal should be complemented with a side serving of Filtre de Gazole also and Filtre De l'Aire with the fresh aromatic of a paraffin soak.

Sir might also like to check the Exhaust Elbow, as these can get overcooked and brittle.

on a slightly more serious note - if it helps - i replaced the filters every year, but to get a strap wrench round the fuel filter you had to slacken off the banjo fixing, then retighten after the change. that was about the only real problem in doing a full 'by the book' service.

what really made a difference was getting the tappets set properly - they do tend to drift off a bit and my 1GM10 always ran sweeter after they were set.

use an inspection mirror to see the timing marks at the back and don't lose the little black top hats or you'll find that your decompressor won't work as one forumite found out

the anode and impellor benefit from change/inspection on laying up but
it's fairly simple to keep the 1GM10 runing well - mine did almost ten years from new without missing a beat with just a little sensible tlc until i sold the boat

washers??

check with yanmar about whether you need to replace the copper crush washers when you replace secondary on engine fuel filters. trying to rescue previously used bentup crushed crush washers can lead to air getting into the fuel at the secondary filter and irreegular or no running....

they dont usually tell you you need to to buy the washers too when you are buying the fuel filters unless your dealer or yard is really sharp.

ask me how i found out about those crush washers haha.

i'd give the little beast some new belts too especially if you see black dust underneath them.

You can anneal the old copper washers and they'll be as good as new, if not better. My propane blowlamp used to do the job, but I parked the car on it a couple of years ago (don't ask) and it seemed a lot of money to spend on a replacement that only gets used once a year to soften a couple of copper washers.

If it's done a lot of hours it might be worthwhile renewing the seals in the waterpump, especially if you operate in water with a lot of suspended matter. Not a very difficult job and you can fit a new impeller at the same time.
