For those following, the last update on the engine was a long time ago when I had begun to reassemble the thing. Here are all of the previous posts concerning the rebuild:
I mentioned in the last post that I only had a few items remaining, but unfortunately those items took me many months to complete. I sort of left the engine at that state and ignored it for a while as the job of sealing up the boat became a bigger priority.
The hold backs came in the form of the transmission, alternator, starter and wiring. The transmission was sitting by the engine for the whole rebuild, I figured it just needed a paint job and that was it. But while it was sitting I noticed that it began to leak oil out of the shaft seal, so of course that needed to be fixed. Turns out that the nut holding the coupler on was a very special type of nut that needed a very expensive type of wrench to get off. I did the math and it would cost less for me to take the transmission in to get a full service as well as the seal replaced than to buy the actual tool. So I took it in to a local shop and got it fixed up, sealed up and working well. It got a paint job and was ready to be installed.
I installed the starter motor and alternator. As far as I knew, both of these pieces worked fine before I took the engine apart. It would always start up very quickly so I had confidence in the starter, but I didn’t know for sure if the alternator was going at full strength. I assembled the engine and connected the wiring harness, just to see if the starter motor would crank over. I turned the key and nothing happened. Welp…time to trouble shoot this mess.
In order to give my self some piece of mind, I took the starter and alternator into a shop to get checked out. Turns out the starter needed a new solenoid, and the alternator was putting out only about half of its rated amps. I wanted to upgrade the alternator to a higher output unit anyways, so I purchased a new 80 amp (55 amp was the original) alternator. The starter was in decent shape after the solenoid replacement, but the shop had a smaller and more efficient starter in stock that I could buy at a decent price. I bought it and will have the original one as a back up.
Then came the issue with the engine wiring itself. The original wiring was poor quality, un-tinned wire without heat shrink terminals. The connections were loose or corroded, and in the end I decided it all needed replacing. Instead of shelling out big bucks for the official Yanmar wiring harness, I rebuild the wiring myself using high quality materials. In addition, I had to re-wire the instrument panel as it was a complete mess of corroded terminals, and I needed to add new male-female connections to replace the wiring harness.
The great part about having to re-wire the engine and instrument panel, as well as the alternator was that I got to learn all about marine DC electricity and how to efficiently put together safe and relivable connections. All of which I will need to do plenty of when re-wiring the boat. It forced me to break out the batteries to see how they are, to start to figure out how I will be wiring up my charging system, and overall mapping of the electrical system. The engine and instrument panel wiring will probably be one of the most complicated electrical nightmares on the boat, so getting it out of the way early leaves me full of confidence to tackle the rest of the electrical system.
All of that took a bit of time working on and off while focusing on other projects as well. This weekend I finally had all of the pieces together, and decided to see if I could crank the engine up…….
Other view from the phone camera I was trying to (unsuccessfully) hold…
and with that…the engine project is complete!! I just need to put her back in the boat when the engine room is all ready, align the engine to the shaft, and hook it up.
To put this all in perspective, I had ZERO mechanical skills going into this entire project. Now I just finished a major engine rebuild successfully. There is no excuse for you to not learn the skills you desire, with the internet at your fingertips you can find all the information in the world…or at least get pointed to a book with the info.
Very very happy right now
AT LAST…the big windows are FINALLY in! This is a huge step for me, as this particular project was much more involved than I ever expected it to be, and was a crucial step to sealing up the boat. Windows, ports, portlights, deadlights…they have many names; but for now I will just refer to these as windows.
Long time readers of the blog will know that I’ve pondered the question long ago what I will be doing with the large cabin windows. The original ones were very thin acrylic with cheap plastic frames and barely sealed in. They leaked, they cracked, they were overall unsuited for offshore work as I’ve read a few accounts of DE38 windows breaking easily under the pressure of waves. These windows needed an upgrade for safety as much as appearance. I pondered the choices for replacing the windows long ago here: http://www.thequestforwindandwaves.com/?p=227
Since then I have pondered further, and after much research I finally settled on the materials and the method for installing. In the end I decided to make my own windows out of tinted cast acrylic, installed using a fastener-less method with Dow Corning 795. I won’t re-write what has already been written on the subject, so I will just link you to the most important pieces I found that summarizes the research:
1. Maine Sail (link), renown guru of all things sailboats summarizes the choices between lexan and acrylic (plexiglass), the various sealants and methods of installing including the recommendation for not using fasteners. here: http://www.sailnet.com/forums/1000233-post16.html
2. This is an article that many people reference for installing fastener-less windows, aka “Sexy Windows” (click here for original Cruisers Forum discussion). The author originally uses heavy duty 2-sided tape for the installation, but in his notes at the bottom he mentions the current trend of not using the tape, just the sealant: http://www.thecoastalpassage.com/windows.html
3. This is a great article someone pointed me to that details the method of installing the windows using temporary screws to affix them while the sealant dries. I followed these instructions with a few minor variations. I detail some of my installation variations in the picture captions below. http://distributionbizwiz.wordpress.com/2007/09/12/hints-for-replacing-sealing-acrylic-boat-windows/
Using those three links as the basis (and much more forum and article research), I went ahead with creating my windows. Unfortunately, this project was a great example of how order of operations creates big problems. For example, before any windows could be installed, I needed to settle how I will be rebuilding the cabin liner because otherwise I wouldn’t be able to trace out the window openings. That process itself was a huge project because I had no idea how I planned on doing the cabin liner, so I had to make a lot of final decisions in the process. I will write that process up once I am further down the line on it, but will preview it below in the pictures.
At last these windows are sealed up, and a lot of progress can now be made inside the boat. The boat interior was practically outside and exposed to the weather since those windows are so huge. Now I can finally keep the interior clean for projects that require it, and am no longer at the mercy of the weather to work inside the boat.
As with my last few posts, below are a bunch of pictures with the story in the captions.
Downeaster’s come with a neat little butterfly hatch over the main cabin. The “doors” or flaps or whatever they are called have some glass in them to give the cabin some light. Unfortunately, my hatch leaked pretty badly as the sealant in the glass had faded away over time. Like everything else on Windsong, that means a rebuild is in order! This was no way near as painful of a rebuild as the companionway hatch. The most difficult part of this was separating the glass from the wood, as it was all held together by sealant/adhesive and I had to be very careful taking it apart to preserve the wood. The pictures and captions below can tell the story.
Rebuilding the companionway hatch was one of those projects that sounded simple enough, but ended up being a very involved thing taking many months longer than anticipated. Just like with most of the boat, it is only when you take something apart that you realize the full extent of the damage and work to be done.
Sometime when the boat was still put together, I was inside during a rain shower noticing all of the water coming in from various leaks. One that came as a surprise was a steady leak coming through the sliding companionway hatch. I noted it and made sure to investigate it when the time came to focus on that hatch.
The time came and went, and before painting the deck I removed the hatch in its entirety to access the full deck, with the idea that I would do whatever I needed to do to seal up the hatch and make it leak free. When I began to remove the slats that make up the top of the hatch, the horrors beneath were revealed and instead of applying some sealant and calling it a day, I realized I had to rebuild the entire thing.
The pictures and captions below will tell the story:
A major project from the past year or so has been the restoration of the teak cap rails on Windsong. I had hoped the rail was just fine and could be left alone, but with each piece of hardware that got removed from it, the more I realized how damaged it was. On top of that, there were plenty of leaks under the cap rail where sealant had dried up and became useless. I eventually came to the conclusion that it had to come off, get restored, and re-bedded.
The first step came with removing the rails from the boat. This happened some time ago, as they needed to come off before I even started the deck restoration and painting. It wasn’t until I removed them that I had realized the extent of the damage. I had originally feared that they were unsalvagable in many spots, and I would have to replace the wood all together. Fortunately, that wasn’t the case. As with any project, I took my time doing research and figured I could restore the teak and make the original rails last for much longer.
Just to forewarn, I did a pretty poor job of photo-documenting this project. I have a few, but I didn’t photo the restoration like I should. This is in part to the fact that I had my Dad help me out with the initial restoration and repairs to the major problem areas. He took the rails to his garage to work on while I concentrated on other projects. When I got them back, all of the repairs were done and I had forgotten to photo the problem areas to begin with for before and after pics.
The process for the restoration was initiated by the works of Don Casey, who has some great words on how to bring teak back to life. We cleaned each piece thoroughly with Bar Keepers Friend, a cleaner with oxalic acid, a cheap and effective alternative to teak cleaners. After cleaning we gave each piece an initial sanding to flatten out the grain and give us a better picture of where the problem areas were.
As you will see in the pictures below, certain areas where water had been trapped under hardware had been rotted away. Other areas were broken off due to collisions or whatever reason. Some areas were just soft and worn away. Where possible, we just fixed bad areas with teak plugs, but areas with small enough diameters to handle even 1″ plugs were rare.
The big problem areas were fixed using epoxy and fillers. You will often read that epoxy doesn’t adhere to teak all that well due to the natural oils in the wood; well when the wood is as dry and beat up as this…it sticks quite well. We initially experimented with wood filler, but that looked pretty bad; so I stuck with what I know and went with epoxy for the rest of the repairs. Some small areas I mixed saw dust from the initial sanding to fill the epoxy, but found that Cabosil and the red fairing compound I normally use with epoxy to do the job best.
Here are the pictures of the rail removal, some of the damage areas, and some of the restoration work:
Damage, and examples of repairs:
One modification I had to make to the rails was to create some grooves where the new stanchion bases will be. The old stanchion bases were just plates bolted to the top of the rails, the new ones have a vertical section to bolt to the bulwark for more stability. This was my first time ever using a router and making a jig, the one I have is just a small trim router. It turned out well after a few tries and errors on scrap wood:
After all of the repairs, each rail received a final few sandings of increasing grit before being ready to install. I used Life-Calk polysulfide for the bedding, in their teak-brown color. Each piece was painted with the Life-Calk primer for good adhesion, and was bedded with a good slab of the goo on all edges and in each screw hole. I beveled all holes with a counter-sink bit to create a good space for the sealant to work into. Each screw hole was then plugged with a teak bung. I had to spend some time making final repairs to some areas that I had missed, and had to open up and re-drill some bung holes that weren’t taking the smaller bungs. The rails then received a final sanding up to 220 grit. The Life-Calk sanded down quite nicely where it had gooped over.
Only picture I have of applying the goop, and a few more of the final sanded wood. You can see a big area of repair in the first picture at the edge of the bottom piece:
Of course, as with any project like this, I spent a stupid amount of time debating on how I would finish the teak. As some of you may have read previously, I have been restoring the interior wood with varnish. Varnish is gorgeous, but in the tropical sun it is an intensive thing to keep up with and maintain, way too much for my tastes. I have been using Cetol Natural Teak to finish my restored hatches, and have really liked how it looks. It is less fussy than varnish, and lasts longer in the tropical sun, but it still needs some care and maintenance. I am fine with the few pieces that are getting the Cetol, but the cap rail is easily the biggest area of wood on the deck. Of course, there is the option to leave it alone and let it silver, but I just spent countless hours restoring this wood and I would like to protect it somehow. Regular oiling didn’t appeal to me, as it didn’t last long and was prone to blackening as dirt collected.
After doing much research and going back and forth between Cetol and anything else I could find, I ended up going with Starbrite Tropical Teak Oil Sealer. It was recommended by a few people on the Cruisers Forum, and it seemed to fit the bill. It lasts a good bit, though not as long as Cetol, but it initially only needs one or two coats that can be applied in a day. Maintenance coats are easy to apply. I bit the bullet and bought a can of Starbrite, and after applying it to some test pieces came away pleasantly surprised.
I spent a day with Jenny applying two coats of it to the cap rails, and I think it looks fantastic. It sealed up the wood just right, as tested with a hose and you can see the water bead in the last few pictures.
It feels absolutely outstanding to have such a big project finished.
I promise I have been working hard. Many projects are about to be complete so write-ups will be coming soon. Here is a picture preview of the fully restored caprails, finished with Starbrite Tropical Teak Oil Sealer
So far I like this stuff. I screwed up applying it on the deck a few times. Once I did it when rain was coming..stupid mistake. The other too late on a cold night so the bumps flattened out before it dried. I had a few successful sections though. Painting it on the locker lids in the garage was really easy.
I’ve been Instagramming my projects more and more, you can see the thumbnail feed on the right of the page. Here are some from the last few months to catch you up.
