    The bad news: still short the gasket that goes under the fuel injector, ordered that today along with a fuel filter and fuel filter canister O-ring.
    The good news: found out while studying a piping diagram that the factory fuel return line doesn't go to the fuel tank.  It goes to the fuel filter canister.  I can use any fuel tank I want.  Hooray!

    See your 'fernow' and raise you a 'round tuit'.

    I have found that the definition of permanent is temporary that works. Lots of temporary things on Easy Go that I have not got around to changing and possibly never will. I prefer to sail much more.

    A cruising friend of mine called those things (like a LH Prop mounted backwards) as fernow's as in that's good enough for now.

    Flutterby has her share of them. Some have been in place for four out of the five years we've owned her and show no sign of being done "right" yet. But someday I'll get to most of them...or sell Flutterby first!

    Jeff, just keep on going and you'll get things working, one way or the other! And let me tell you...it is SOOOO worth being under sail, even if it takes 20 "fernow"s to rig it up!

    Today I finished installing all the parts I had taken off the aft end of the engine.  If this thing was on a bench I could have done the entire reassembly in an hour and a half.
    Remaining to do is put in the new injector I bought for it and hooking all the fuel lines back up.  I've got a question for the group, but I'll have to take a picture tomorrow to post it.
    I did find a hose hanging dead-ended under the bunks in the aft cabin, all rotted soft like it had been a water hose used for diesel.  It comes from the forward end of the motor; I'll track it down tomorrow.  
    Lots of half-a$$ workmanship on this vessel.  Not a problem, it gives me something to do.
    I've decided that when I launch it this spring it'll be in a local lake so I still have access to both my workshop and it.  There is too much left to do to take it to the coast and try to live aboard for a season.  Maybe next year I hope.

    And of course, that is the right and proper attitude.  But if Jeff does everything the correct way, he may end up sailing his coffin before Seablossom.  Maybe quick-and-dirty is never justifiable, but there are many times that it's excusable.

    I know my suggestion is incorrect (remember the sucking of teeth when we did it?), but how many hours is Jeff going to put on this engine?  How many hours are needed before the injectors are slightly damaged by the incorrect temperature of diesel through them?  We fitted the engine in question between tides, in a Falklands Islands winter, 100 miles from the nearest shop.  It was not done the correct way in many respects (we used alloy beer cans to create shims- it was the only time Pete didn't look a bit po-faced when I drank a second beer) and I think I'm correct in saying we put the propeller on back to front because it was the left-hand instead of right, or vice versa.  But that engine helped us in the South Orkney Islands and South Georgia and on to South Africa.  We did change the prop sometime, but I don't remember where.

    My point is that Jeff is reaching the point of overwhelming frustration and I think his dream takes priority over the engine's ultimate welfare.  Whatever it takes.
    Not to worry.  I was pretty low when I posted that, but I'm not as down as that sounded.  I'm plugging away, putting external bits back on the engine before I can try it, but the old valves were seriously toast and they're well renewed now, so I'm confident that it will chug along.  There's not that much to a diesel.
    Then it's finish the partners and step, step the mast and arrange all my blocks and cleats, build a sail... Not necessarily in that order, because I can build a sail before it gets warm enough for epoxy to cure so that's probably next after I finish the Yan.  One day at a time.

    Yes, that's it, freeze in winter, bake in summer and the tool/part you are needing is always where you are not. Messing about with boats is fun! Might even do your paunch some good :-) but I found that the consoling beers/wine/whiskey needed afterwards balanced or even retarded any good that the exercise might have done :-(.

    You can easily check if you have a diesel that relies on the fuel for injector pump cooling. If little or even no diesel comes out on the return side, it's not using the diesel for cooling. When the fuel is used for cooling, you will get quite a healthy flow. However I like doing things the correct way and so keep them separate.

    Put a few more pieces back on the Yanmar today.  The "engine room" on an aft cabin Nor'Sea 27 is a torture chamber.  The engine resides under the cockpit; the forward end of it is accessed from the back of the forward cabin by removing the companionway ladder.  The aft end is accessed from the aft cabin by (you guessed it) removing the companionway ladder.
    Most of my tools reside in the forward cabin, so the general process is: go to the forward cabin, put on some part, put in the forward bolts, put in the companionway ladder, go to the aft cabin, start the after bolts...
    go back to the forward cabin for the tool I forgot...
    Lather, rinse, repeat.
    All this is made more entertaining by the fact that winter has us in a firm grip, with highs about five below zero C and lows about -9.  I'm running a little portable camping propane heater to keep it reasonably comfortable.  Given this, everytime I move from one cabin to the other it's open the hatch, lift out the drop boards, curse the drop boards, reinstall the drop boards, close the hatch, go to the other cabin, open the hatch, remove the drop boards, curse the drop boards, clamber into the cabin... you get the picture.
    Makes no difference.  I'm making some progress, that's all that matters.  I don't know for sure if it will run when reassembled, but it ought to.  The valves were horribly burned and pitted, and now they're smooth as can be.  There's not that much to a diesel.
    Oh, Paul - re, old, slow turning diesels: This is a 1979 Yanmar that peaks out at 1800 rpm and doesn't produce much power doing that.  But I'm not planning to T the return line anyway.  To my way of fiddling it'll be easier to create a return line fitting.  There's no pressure on it so it won't be stressed in use.

    "Don’t worry; the one who has never failed, has never done anything".
    By that standard I have done much.  Ah well.  Time to go out and bend my paunch.
