Yanmar 1GM Fixing leaking water pump, bleeding the fuel line, test run ok. 

I had a Yanmar 1GM sitting 20 years on my workshop shelf. Decided finally to sell it, and serviced it for the new owner. New oils, new filters, new sink, new impeller, checked the fuel lines. The engine has run only about 300 hours so far. It started and ran ok, but I noticed the water pump was dripping. So I ordered new lip seals and fixed the pump. I thought somebody might wanna see my way of doing it, (although there are many videos of it already) so I shot a video of the process.
