I have been amazed what you can do with a manual impact driver.

Ahoy!

I owe you the last chapter of this story.

I purchased all the tools I needed last week, including a small torch. Last Friday night I decided to test again the tightness of these oil plugs, half by curiosity and half by (bad) temper. I placed a wrench on my screwdriver, put on some gloves.... and the plugs came as if they were screwed in butter!

I am not sure how to explain that, but I think the WD40 I sprayed on a few days ago may had work their way through the gaskets, the temperature had risen noticeably, .... and that time I was wearing gloves! Three days before I was about to break the heads of these plugs, then on Friday I didn't have to give that much effort... Whatever... :?

The flushed oil had a beautiful green colour and was only very, very slightly cloudy. I am guessing it could have been used for a couple more seasons. The boat was launched, the engine started without choke on the first pull, I got my first sunburn of the season.

The torch wasn't lost: I discovered it was much more efficient than a lighter to burn the end of ropes...

All good! :)

I used a hand impact. Big screw driver bit on one end and you wack the other end with a hammer.

Please don't ever use an impact driver on your engine case or leg as suggested in this post, it is cast aluminium (or aluminum for you in the US), do this only at your own peril, you run the risk of cracking the case and man is that expensive to fix.
