      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

After servicing my Yanmar 2GM changing oil, filters and belts, I noticed a leak on top of the injectors. After some research, I found that it is easy to replace the bolts and gaskets, and that removing them won't affect the injectors. It is a low pressure return pipe that ends open in the tank, so no high pressure involved. I also change the pipe.

 

These are the replacements pieces:

(1) 105311-59500 Fuel return pipe

(2) 101147-59810 Bolt

(4) 23414-080000 Gasket

I bought a 1975 Bystedt 30 one year ago. The boat is powered by a Yanmar 2GM (the old model, older than 2GM20). The engine is connected to a Cessna hydraulic pump. It took me a long time to find the stamped model in the flange, 5H 12 PA - 70142 RAG, which according to http://knighthawksupply.com/cessnapumpid.htm means Product type 701, Pump configuration Tandem, Displacement 0.84 in 3/r and Right-Hand rotation. All this is located below the cockpit. Hydraulic liquid is pumped there to the hydraulic motor in the bilge, with a load adaptor that connects with the shaft.

 

The hydraulic motor and the adaptor were totally rusted, the shaft almost loose. I found a clue of what happened to the boat in a blog of the previous owner. He was 20 miles southwest of Cape Flattery, when the bilge start filling up with hydraulic liquid, and the shaft stopped spinning. He adds that the previous owner told him "It's a closed hydraulic system - both ends are identical.".

 

I asked for advise in a boatyard nearby, and they told me they could fix it for $12,000. That's more than I paid for the boat, so I decided to work on it myself. Dave, a local boat mechanic lend me a hand, and we removed the old unit:

We found out that the problem was the adaptor, so we found a replacement (that was about $1,200). The replacement didn't match the exact size of the previous unit, so we had to make some adjustments on the metal sheet that served as a base. After all this, Dave installed the new one and repainted the whole thing:

It works like a charm now. The whole thing took us a couple of months, but in Seattle the weather encourage us to work inside the cabin.
