Want A Lift?

Okay boys and girls today’s lesson is about Water Lift Silencers. What in the world is that? Well, I’ll tell you Shouty. It’s that round thing under the deck behind your engine that helps the exhaust push the water out the exhaust port usually somewhere near the aft your your boat. It can easily be located when your engine is on and the water and gases are spewing out into your wake.

There are all kinds of lift silencers but this one is mine. Dazzler is fitted with a very old fiberglass style with both the exhaust in and out ports on its top. It is a cylindrical sealed can with an approximate 1.5” flange on its bottom for fastening it to a platform.

So what’s all the trouble with these things? Do they have a life expectancy? Can they go bad? If so, what causes them to go bad? I sum up these questions with our experiences over the last several days.

First, I’m not sure if this is the original lift silencer on Dazzler or not. I suspect so though. I have owned her since 2003, and she is now 32 years young. I knew where it was located, but honestly didn’t know much about how it worked or what to look for in the way of issues. One of the two previous owners had it installed or installed it themselves. When it was installed, the angle of the elbow that connects to the back of the engine apparently was modified from a 90° elbow to an approximate 30° down angle. During the modification process, as determined by the crack I found, a regular 90° elbow was cut to accommodate the needed angle and a putty similar to the Minute Mend that I used to make our emergency repairs was used to complete the modification. Perhaps the instant epoxy has a use life also. Years of vibration and almost 6000 hours on the engine had finally hit that magic age of disintegration. LOL How do I know these things?

Well, two days ago the engine stopped spraying water again. No big deal as we’re just putting up the sails again. We sailed through the rest of the night and into the next afternoon before I had to tackle the new water leak situation again. It seems that I missed this crack because I couldn’t see it during the second fix. Hence I pulled the entire silencer out of the engine compartment to better diagnose and attempt to fix ANY and ALL cracks this time.

I guess third time is a charm. After grinding the areas around the several additional cracks I found, I filled up the canister with water to see if it had any other leaks. It’s flat bottom is also fiberglass and is joined to the flange of the bottom of the canister. When it was installed. The installer drilled through the flange and into the mounting deck. This held it firmly in place but it also put eight screw holes into the flange that apparently should have been avoided as all eight holes leaked water. I’ll tell you how I tried to fix this issue later. While the minty flavored dog poo was setting up From the new application, I refitted the silencer to its mounting deck. I used some wazoo pipe thread sealer I found in Papeete on the screws before I inserted them and fastened the silencer down. Yes, I magically found all eight same screw holes without too much difficulty. Not bad for upside down blind left handed screwing. Actually, I used a Sharpie marker and marked one of the holes and as for the rest the silencer just kind of fit in place. Both hoses were connected as designed. We waited an extra 10 minutes for it to set before I fired up the beast. You’d have thought I was waiting for Santa to come down the mast or something. I was impatient so I found putting away tools occupied me for several minutes while I waited. We fired up the beast and tada! No leaks from the hose connection. Yay! The bottom of the canister was a different story.

As it turns out, one of my Diesel engine repair manuals by Nigel Calder talks a little about the water lift silencer. Apparently a back pressure 1.5 PSI is present to help force the water out to the back of your vessel. That’s good because I’m not sure I could seal it up for any more than that. Additionally, Mr. Calder recommends breaking lose your exhaust connections and inspecting the inside of hoses for excess soot, oil or anything else at least once a year. Catch it before the surprise of not working properly when you least expect it. It will be on my annual inspection to do list from now on.

To answer the question of what the life expectancy is would be like answering the riddles of the universe in one word. They may, but I would recommend routine checks while servicing your engine. You know hands on eyes on while it’s running if possible. I have to admit that this was not something on my radar of things to check. To make sure it doesn’t develop a crack like ours did for whatever reason, defect, installation or old age, I’ll be checking our new one during regular engine services in the future. I only look upon our repair as an emergency repair and yes, we will be getting a new one in New Zealand.

I write this for all my boating friends out there that at the very least ask their own questions. I wonder if mine might be leaking? Do I have one of those? Is it in good working order?

If this helps just one other person to avoid potential exhaust water lift silencer issues then right on!

Now it’s back to sailing in a cold, cloudy environment. We are less than 200 nautical miles from Marsden Cove Marina where we will check into Country with Customs, Immigration and Bio-Security. We have about 14 knots of wind out of the North on our port quarter, the seas are relatively flat and we’re making 7 knots. Hang on Grape Ape! He likes to be part of everything. What are you gonna do? Teenagers!

Cheers!

It’s Not All Fun & Games

We know that to many of you it probably looks like all we do around here is play but the truth is that living on a boat full time is a lot of work. During the six months we are here waiting out cyclone season in New Zealand we have a list of projects to complete that’s as long as Dazzler. Many of these things can’t be done in the islands because you just don’t have access to supplies so when you do, you have to work.

SO TRUE!

If you know anything about boating you know that no project is ever easy. What starts out as a simple project can quickly become a massive one and some projects are tedious and just take a lot of time. Dan does just about everything on our boat. I’m sure you’ve heard me say more than once that there’s nothing the man can’t do and he proves that time and again. One of his favorite things to do on the boat is to varnish her. Yeah, I know, sounds like a sentence not a pleasurable activity but Dan loves it and when he’s done it’s nearly perfect.

I’d be more than happy to help him but there’s two reason he won’t even think about it. The first is that I shed like a long haired pup and long black hair doesn’t look very good in the varnish. The second reason he won’t let me play the varnish game is that he is an absolute perfectionist and he’s afraid I won’t be able to do it exactly the way he does. Honestly, it doesn’t really hurt my feelings that much. I mean, varnishing is a lot of work and I’d just assume stay below deck writing articles and creating videos for you fine folks.

Dan recently spent three weeks varnishing Dazzler’s cockpit. This time he needed to take it back to bare wood which meant it would require eight coats of varnish! Yes, that’s a lot when you consider he has to sand in between each coat. And, like I said, no project is easy. Just after getting started sanding the cockpit he found wood rot in one of the seats. This required him to completely rebuild the seat. He’s never done anything like that before but he didn’t let that stop him and the finished project was perfect!

And there’s been a whole host of other projects from cleaning stainless to removing the sails for when we take our trip back to the states. There have been parts to find and engines to service. In the two months since we arrived Dan has replaced the front main seal on the Yanmar, serviced the shower bilge pump, rebuilt the propane locker door, cleaned the rigging, replaced the deck waste fitting, replaced gimbal brackets on the stove, rewired our steaming light, installed a 240V battery charger, had injectors and our spare alternator serviced, varnished, and even managed to fit in a bit of sight seeing. I guess you could say he’s been a busy man.

It’s a whole lot more fun doing it this way than in a bucket on the deck of Dazzler.

As for me, I’ve been maintaining things below deck, writing, making videos, cleaning, cooking, doing laundry and doing research and planning for a three week trip to the South Island with our friends, Jack & Mary, who are coming here from Los Angeles. Not long after they leave we will be making a trip to the U.S. to visit our families for a month. We’ve got lots going and before we know it cruising season will be upon us again.

But don’t think we won’t pay for the “vacation time” because when we get back Dazzler will be on the hard and there’s a bottom to paint, deck repairs, a thru hull replacement, provisioning and a list of other items that must be done before we can take off for this year’s cruising season. Yes, the sailor’s life can be exotic and take you to amazing places but there’s always work that must be done. As Dan always says, “Nothing’s free in Water World!”

Until next time,

Oh No! Not The New Honda!

During our journey this last summer our Honda EU2000i generator had decided to take the big dirt nap. Necessitating a replacement be shipped to us in Nuka Hiva, Marquesas.  We use the Honda daily to assist in recharging the batteries, making fresh water and occasionally heat the water heater tank.  Needles to say we were happy to see the new one arrive before we continued our travels.  Wow!  I was glad to be able to give the Yanmar engine a rest from charging batteries when needed.  It was great having a Honda back online aboard Dazzler.

Everything was working well for several months.  About a month after going online the pull cord to start the generator started to fray.  No trouble, I have plenty of cord onboard.  A quick replacement and she was back in business.  About a month later the cord started to fray again.  Okay, now I’m starting to wonder what’s going on.  We were in VaVa U group of the Tonga islands when it happened the second time.  No trouble, I would replace the cord with a bite of Spectra cord which should be a bit more abrasion resistant than the nylon cord.  After getting Jack put back together, it wouldn’t start.  We called the generator Jack, because of all the assistance our friend Jack had done in helping us acquire the new generator.  

I hadn’t disconnected anything and it had been running that morning before I decided to replace the starting cord.  I have to tell you that after taking the end covers and the side covers off and putting them back on more than eight times looking for and diagnosing every wire and the carburetor, I was at my wits end.  Still no spark to the spark plug.  There are only five electrical components that could be the culprit.  Including the wiring harness.  I checked each piece for its factory resistance or ohms and everything seamed to be within specifications.  If everything is in specs then it could be the sealed electrical spark unit.  Nice!

I’m usually not a quitter, but this time I was.  I didn’t know what else to do. There is no Honda dealer in the Tonga island group to get parts and the closes supply would be New Zealand.  Many of the parts on our EU2200i are similar to the EU22i (European model).  It is sold and distributed in parts of the world that use 240 volt 50 hertz cycle electricity.  

We checked into the. Possibility of having a spark unit shipped to us in Tonga which was possible, but extremely cost prohibitive.  So, we decided to fire up the Yanmar again and wait for New Zealand.  I had checked online and the Spark unit for both model generators was the same part.  

After arriving in New Zealand, we went to North Coast Honda to order a new Spark unit.  A couple of days later it arrived.  Imagine my excitement.  I rushed back to Dazzler to install the new part and Shazam!  It didn’t start.  Okay maybe I didn’t get the wiring plug seated properly.  Yea that must be it.  So, I took the end cover off and re-plugged the wiring harness into place and put the cover back on.  Ready…1, 2, 3…no start!  WHAT the H E double hockey sticks?  Or something like that.  There I was removing all the covers again checking everything to no avail.

I decided that Honda was going to get the honor of our Honda generator for repair.  Once at the shop I explained to the technician what I had done and what had been replaced.  The service man was Paul Newman.  Who knew he was working at a Honda dealer in Whangarei New Zealand? It’s always the last place you look.  HA HA! They accepted it without a service receipt and said they would let me know.  Paul did tell me that Honda New Zealand is a private company and not a direct part of Honda global.  And although Jack was only four months old they would not be able to provide any warranty service on our unit.

Well, Jack was only four months old so I decided to contact Honda USA to see what they would be able to do for me.  The first response was “sorry you have to take the generator to one of their service centers”. And because it has had gas and oil in it NO airline would accept it for shipping to the Good ol’ USA. So it either was going to get fixed here or tossed into the trash heap.  We needed it.  I decided to go to the next level and ask for the supervisor at Honda Equipment Center.  Enter John into the picture.   I explained to him our situation and although sympathetic to our predicament he did not initially offer any warranty hope.  I did provide the Honda service center in New Zealand information to John as he offered to contact them to see if he could be of assistance in determining the problem.

To make a long story short, the Honda technician here in New Zealand found the same thing I did as far as the resistance and ohms for each piece of equipment.  The spark coil was a little off of specifications. So they decided to replace that first.   That didn’t work.  They did some more testing and put the spark coil on an EU22i and it worked. Now we are getting somewhere.   Well after ordering a new wiring harness provided by John of Honda USA and a few weeks of shipping time it arrived and was installed.  Now there was spark, but still not starting.  They removed the head and found that the intake valve arm was cracked and the intake valve was frozen in the closed position. 

Once again with the assistance of John at Honda USA, a technique of freeing the valve without breaking the motor case open was conducted and the valve was free.  The Honda dealer had an older Honda generator that they were using for parts, so they robbed the intake valve arm and after putting in some fresh gas…Jackie was alive and running again.  

The Honda dealer was unable to explain how the valve might have become stuck so I could avoid it in the future.  I suspect that after it lost spark in Tonga and then sitting idle for two months had something to do with the stuck valve.  When I arrived to pick Jack up and pay for the bill, they gave me the old wiring harness.  

After returning to Dazzler with a working Jack, I checked the ohms on each wire in the old harness. John had first told me that many times an issue has been a poor ground connection.  Hummm, when checking the ground wire, I discovered some interesting readings consistent with a poor connection.  Could all of this trouble have been right there all along. Well, we won’t know for sure because there is a new wiring harness in place.  But, I’ll put that tidbit of information in the memory banks for future issues and being able to help others that use a Honda generator.

A few days later, I fired off an email to John at Honda in the USA thanking him for his assistance to the Kiwis in getting our generator up and running again.  I also re-approached the warranty issue with him again.  Several days later I received a message to give him a call.  He advised that Honda was going to offer a good faith payment for our inconvenience that worked out to be a little less than half the service bill at Honda in New Zealand.  Better than a poke in the eye with a stick.  

I did ask John several questions to help avoid any of these issues in the future.  He indicated to always use fresh fuel if possible. Hummmm, fresh gas in the South Pacific might be hard to come by all the time.  John also indicated that turning the switch off and  pulling on the start cord until you feel resistance will put the crank at top dead center and both valves would be closed. He explained that this should be done when the generator is turned off and it should help aid in preventing stuck valves in the future.

I can’t always get fresh fuel in some of our destinations, so we will be looking for a source of gasoline additives to help stabilize the fuel that is stored.  I’m not sure this will be the end all, because the Yamaha outboard uses the same fuel and we very rarely have any issues with it. Keep in mind that I regularly service it as well.  The bottom line is _________ we will see what happens with Jack’s continued service in the future.  Until then once a week Jack is started to keep things lubed up and everything running properly until we get back to the anchorages and needing daily use of Jack.  

So turn Jack off and pull his cord until it gets hard before you put him away for the next use.  LOL

Cheers Mate!
