It has come to our attention that there was an awful noise in the beginning of our video posted yesterday of our passage from Fiji to New Zealand. We have corrected that and the new video is uploaded. Click on the photo below to see the revised version.
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!
I’ve spent the past two days searching Dazzler from stem to stern and still can’t locate the tiny hidden cameras. This has led me to believe that either they are some microscopic feats of engineering that are undetectable to the human eye or that we are not in fact part of some evil psychological experiment. If the ladder is the case then I can only assume that we have surely been involuntarily cast in some aquatic themed Twilight Zone episode. I think I can even hear the music drifting over the sound of the sea as I write. Dododo…dododo!
Why would a perfectly sane (well somewhat sane anyway) sailor believe this? Well, let’s just recap the past 24 hours shall we? You already know everything up to that point and honestly I think that alone would prove my point but let me add some fuel to the fire of madness in my head so that you too can join in the delusions that presently afflict my muddled brain.
Yesterday was a truly delightful day on the sea. We had amazing winds and the swell was just right. The sun came out to warm the air a tad and we were sailing across the open ocean with a certain assertiveness that comes from being truly confident that you finally have your whole world under complete control. Both Captain and mate were beaming with pride as Dazzler cut through the swells with determination and grace. The white foam of the ocean splashed high above her bow as she plunged into the sea in her typical dramatic flair. Yes, this was the most perfect day of the seven we’ve spent on this roller coaster passage from Hell. Smiles were abundant and hope was in the air.
We performed our expertly choreographed passage routine like true professionals switching between watch and naps, food preparation and mealtime. Finally as the sun began to dip low in the sky I too looked toward a night of slumber in my warm and cozy bunk. I confidently left Dan on watch in the cockpit. The winds had dwindled so he had put on the engine to keep us moving at a good rate of speed. We were still trying to make up time that was lost over the past couple of days and there’s still that pesky low pressure system we’re racing to New Zealand.
I slept soundly with the crashing waves thundering away against Dazzler’s stout hull and when I said my prayers I thanked God for a glorious day without so much as a simple problem…err challenge as Dan refers to them. Before I knew it Dan was waking me for my normally scheduled watch. As I began to stir I asked him why I thought I heard the engine go on and off several times. He told me he’d tell me when I got up. That “Oh holy hell” feeling washed over me like the tsunami that hit Sri Lanka years ago but just then I remembered my pledge to try to keep a good, can-do attitude about these “challenges” so I crept out of the bunk and let Dan begin explaining the newest hurdle in our race to New Zealand.
It seems once again we have no water exiting Dazzler’s exhaust. Cue the music …. dodododo dodododo. “How can this be?” I calmly question. “I’m not sure.” He replies. “But I will figure it out and fix it. Don’t worry. I’ll fix it.” He goes on to tell me that we are sailing nicely and don’t need the engine right now so he’s going to get some sleep, have me then get some sleep and when the winds begin to die he will clear out the lazarette (almost as bad as emptying the quarter berth) and he will go down and fix it. With that he kisses me goodnight and retires to the bunk for some well earned rest.
I, in the meantime, gather my watch materials and snacks and head to the cockpit. After completing my instrument and sail checks I sit beneath the dodger where it’s out of the wind and a bit warmer. I gaze out to the ocean and as I do it dawns on me. I’ve absolutely zero emotional response to this news. I’m not mad, frustrated, frightened, sad….nothing. I’m completely devoid of all feeling whatsoever. I guess it could be called being at peace except for I just wasn’t feeling anything at all. It was odd to be sure but I kind of liked it!
I think I’ve finally resigned myself to the fact that there is nothing I can do about any of this. I certainly can’t diagnose and fix the problem. I believe in Dan and his ability to do so wholeheartedly so I just need to sit back and let Dan and God do what they need to do. The rest of my watch I hardly thought of the issue at all.
I wake Dan at 0400 for his watch and make him coffee as usual. We’re sailing along at close to seven knots and we have following seas which is making it a very nice and somewhat speedy ride. Once he’s clipped in on deck with his go juice I head to the bunk. I’m hoping to sleep well because I know he’s going to wake me in a few hours so we can tackle our newest challenge.
Several hours later I hear the Watch Commander alarm go off. The beeping goes on just a little longer than normal so I wait…it continues so I jump out of bed calling for Dan. As I race up the companionway stairs he’s nowhere in sight. My heart is driven into my throat like a shot from a pistol as I climb higher to get a look on deck. My head swings right then left. In the light purple haze of the dawn I finally see the dark outline that is Dan standing on the starboard deck holding onto some line as he’s tightly gripping the handrail on top of the dodger. Dazzler is healed over close to 30° as she’s slicing through the sea at top speed in the 20+ knot winds that are blasting our port quarter. There’s white water splashing up behind the dark figure and then the Watch Commander sounds its 130 decibel alarm. In the confusion I forgot to reset it.
As Dan steps into the cockpit I reset the alarm asking what is going on and why the hell he was on deck without me being up. He tells me the jib sheet got ripped right out of his hand and he had to go get it. He says he needs to walk it back around deck. I suggest that maybe we could wait until the winds die a bit and it gets a tad lighter out. He agrees as he tosses the line into the cockpit. Having been in a deep sleep before being rousted by the incessant beeping of the Watch Commander I was not dressed to be outside. It was cold and damp and I needed more clothes. I went below to curl up in our thick Sherpa blanket in the bunk for a few minutes to get warm before I got dressed.
This would probably be a good time to tell you that we have a hard and fast rule on Dazzler. No one, including the Captain, is to go on deck without making the other person aware that they are going there so they can keep watch. It’s a good safety rule and one that my dear Captain has been known to break. In an emergency such as the line taking off and him needing to get it I can understand and forgive him. That said, what happens next was not one of those times where I could just look the other way.
I’m in the bunk warming up and all of the sudden I hear an out of the ordinary sound above my head. I stop and listen a bit harder and realize it’s footsteps. “Are you freaking kidding me?” I gasp as I go back up the companionway. As I do I see the winds have jumped up to 24 knots. We’re screaming through the water as I look toward the bow and there is Dan on the port side restringing the sheet around the deck.
Remember that feeling of nothingness I had on watch? Well let’s just say all feeling has returned and the emotion that immediately rears its head is pure anger. “What in the hell are you doing on deck without telling me?” I scream above the wind and waves. “We have rules damnit!” You think the wrath of a woman scorned is bad…try a woman at the edge of her sanity on a boat hundreds of miles from shore as the love of her life is on deck breaking one of the most critical safety rules of all. It’s not a pretty sight and one that would strike fear in the hearts of the most macho of men.
Dan returns to the cockpit explaining that he yelled down to say he was going on deck. No! Just no! We have had this discussion many, many times before. If you don’t get an acknowledgement you must assume your message was not received and act accordingly. I’m furious and he knows it. He doesn’t say another word as he clips in and sits down. I storm down below to cool off a bit.
The thing is we never let an argument linger. It’s not worth it and we both know in the end we’re still going to love each other and be together when it’s over. I leave Dan to consider his actions for ten minutes or so then return to discuss what happened. Certainly he tries to defend himself but when I turn the situation around and put me out on deck he realizes that I am probably right and apologizes. I apologize for yelling and just like that everything is good between us again. Just as it should be.
Now we still have the issue of the exhaust to deal with but we’re sailing along at six to six and a half knots so we don’t want to slow down. No, we’ll wait until the winds start dying off and then tackle that. It looks like that will be later this afternoon so we go on about our normal routine.
Mother Nature provided us with some beautiful weather that allowed us a rather spirited sail today running as high as 7 knots with kind and somewhat mellow following seas. It certainly helped us to make up some lost time. Alas around 1700 the winds and seas started to settle down and we knew it was time to get working on the exhaust repair. Dan went on deck to drop the sails and I started praying this would be an easy fix.
With the sails down and the boat slowed to about a knot Dan cleared out the lazarette and went in to see what else had gone wrong. He ended up pulling out the exhaust lift silencer unit. We found a large crack in one of the elbows. Dan filed it down with the dremmel and we used the Minute Mend epoxy to repair it. I’m telling you this stuff is amazing! With this repair we used the last of it but will definitely be buying more in New Zealand.
After an hour and a half of floundering while he worked on the exhaust we were ready to fire the engine. It took several minutes but eventually we had water coming out of the exhaust! I’m sure we don’t need to tell you what a joyous moment that was for us. There was lots of shouting and a few high fives! Of course a few praise the Lords were in there as well. Within 2 hours we were up and running again.
What we hope for now is that the repairs last for at least three more days. We just made the turn near John’s Corner and are now headed toward NZ. Our hope is to arrive just ahead of the 25 knot blow that is expected on Saturday. Nothing like sliding in at the last possible moment.
As for this episode of the Twilight Zone let’s just hope the producers haven’t decided to make it a two parter. I don’t think these two battered old salts can endure much more. Dodododo Dodododo.
Until next time…
Jilly & Dan
