  • Patrick Childress Sailing demonstrates how to Repair, Rebuild, Replace our Yanmar 4JH3E marine Heat Exchanger & exhaust Riser on our cruising sailboat. Also, how to insulate the new marine exhaust riser on our Yanmar 4JH3 Diesel engine. the old insulation was asbestos, but this new exhaust wrap is not.
    In this sailboat repair video, sailor Patrick Childress removes the old heat exchanger and the marine exhaust riser and brings it to a heat exchanger shop recommended to us called Empengani Progress, close to Richards Bay South Africa. They say they can rebuild the Heat Exchanger to like new condition. A new marine heat exchanger from Yanmar would cost $3000-$4000. Yanni Enterprises in Zululand Yacht Club boat yard made us a new exhaust riser out of 316 and 304 Stainless steel. It wasn’t cheap, but it was very well made and needed very little coercion to fit it back on to the heat exchanger of our Yanmar 4JH3E Diesel engine.
    Empengani Progress shows how to take apart the heat exchanger. They then cleaned it all out, welded and rebuilt deteriorated parts of the Corroded cap on the heat exchanger, reusing the core, and then put it all back together again,pressure tested it, and then charged us a very reasonable rate too! Much cheaper than a new heat exchanger! it is always difficult to decide whether to replace or repair a heat exchanger.
    Once the new exhaust riser was fabricated, Patrick reinstalls it. Because Patrick had removed all of the asbestos insulation on the old marine riser, we had to find a new material to insulate the new exhaust riser, and find out how to insulate a marine riser.
    There were many Yanmar spare parts that we needed for this rebuild, and we fell back on our old source in the USA, Toad Marine Supply (aka MarineDieselDirect.com, LaserSailingDirect.com, SunfishDirect.com, BoatDollyDirect.com, and Torresen Marine Inc). They are always responsive to emails, and double check everything with part diagrams to be sure we are all talking about the same engine part. They ship Yanmar, Westerbeke, Universal and Volvo Penta Diesel engine spare parts all over the world, as well as other marine supplies, very quickly and very correctly.

    Few veteran oceans cruisers do hard core maintenance videos that have the clarity, brevity, practical explanation, and focus on getting the project done that Patrick does. One of Le Vagabonde's best videos was how to install a water-maker on a monohull, Riley did a good job but with a background in offshore oil work, he had confidence. I think of Patrick as the Dean of the School of Cruiser maintenance. So, I was surprised when that locally sourced fiberglass wouldn't dry & sympathetic as to why Patrick tried local sourcing, he has faith in people. Your videos are really clear in terms of communicating the message and on boats the message is more boat maintenance is almost always needed. So, I encourage you two to keep presenting content on maintenance.

    I enjoy boat work videos as much as sailing and the adventure segments as well. Be wary of the hose clamps in South Africa. Brian from SV Delos replaced several hose clamps which they were told was a good stainless but were cheap knock off's that rusted out (bands and screw) and caused leaks on their boat. Hopefully you found a good retailer, bought some spares, and kept the old hardware for backup. Love that refurbish and the new riser with the flex coupling. Great Job!

    • @SailingBrickHouse-RVLife

      Thanks for watching. We may have found those same “stainless steel” hose clamps that Brian On SV Delos found...we didn’t buy them. When I was back in the US, I got good quality, true stainless ones from Fisheries Supply in Washington which passed the magnet test, and carried a LOT of them back with me! We could not find any hose clamps in Richards Bay that would pass the magnet test. It is like no one here has heard of using a magnet to test the quality of their clamps. -Rebecca

      @SailingBrickHouse-RVLife  4 ปีที่แล้ว

      Well....there is good access from one side only. A while back I changed the kill pull cable. What should have been a 2 hour job at most, took 8 hours. Even if I had good access on the other side of the engine, the critical connection is so deep inside a Grand Canyon that no human fingers could ever thread the needle of wire and brass stopper then turn the tiniest set screw to secure things. Laying pads on top of the engine, I got real comfortable in that face down position. What helps greatly for changing oil, since the normal oil filter mount is as nearly impossible to get to as the pull cutoff connection, on the far side of the engine,is a remote oil filter, hung on the wall ,and an electric oil pump. Bud, thanks for your comment.

      I was warned, when I bought it, not to touch the new insulation with my hands, which I had done at the store. My hands were very itchy for a day! I want to wrap the new insulation with something, like one commentor suggested, thin aluminum wrap, as it is hard to work in the engine room without rubbing up against the insulation. Good idea, the talcum.

    I had never seen an exhaust as well thought out as yours. With the riser going waaaaay above the waterline and a downward slope to the exhaust through hull (presumably). Too often I see an anti Syphon loop with the rubber valve plugged (disaster waiting to happen) but this is well thought out.

    • @SailingBrickHouse-RVLife
      @SailingBrickHouse-RVLife  4 ปีที่แล้ว +1

      I remember way back seeing a figure for a riser height minimum and I thought it was 18 inches which does not seem to be much. There are a few well known boats which had their engine flooded in stormy weather because of two low of a riser. Our riser is 32" above the water line. The flexible section of pipe near the lower end makes it easy to adjust the height, a bit, for proper fit.

Some good tips also, for those really paying attention.....we all use hose clamps, but does everyone set the clamp screw on top to mitigate damage if the hose leaks? Good one! I eliminated all the open band clamps and replaced all with closed band clamps. More expensive size for size, but I have near enough eliminated rusting, breaking of the clamp, stripping of the gears.

    This heat exchanger issue is a yanmar sickness.
    I had a 4jh4e with 7000 hours and 7 years old have a pretty nasty corrosion surprise on the aft cap side .
    Yanmar dealer used a hydraulic press to remove the core with the warning the entire case could explode.scarry but went well. It took a huge amount of force.released with a loud bang.
    Yanmar wanted 800.00 to repair in phuket. But i got a local to do a 100.00 perfect repair. The corrosion was removed and he machined and sleved the pitted erea.
    It went on another 8,000 hours and its now a spare part for my new 4jh5e. I replaced the 15,000 hours engine though it was running perfectly. I did this for cost management. Yanmar guy said this corossion happens when engines are not run enough. Well i cant agree as i put 15,000 hours on in 11 years

      Phuket, what a miserable ripoff place that is. I have heard terrible nightmare stories of overpriced, shoddy, work being done there. Not an engine story but all we needed was a teak table to replace the one in the cockpit. Any marine facility wood shop, we asked, wanted $1,000 to make a new one. We never had a table in our house that cost that much. We had a new cockpit table made at a local furniture shop for $110. A diesel mechanic recently said that the heat exchanger O rings dry and wear out over time causing a leak. They should be changed at intervals. But he never said how often they should be changed. I think I will start doing it every 1,000 hours. Good to hear you got a great run out of your Yanmar. That gives me hope. Good idea to swap for a new engine after so many hours. I am very surprised that a Yanmar dealer would just press out the corroded core. That sounds brutal and risky. I would think they would soak it first to loosen it up. Thanks for your comment.

      Phuket is a place that if you can take the time and really do youre re search you can get good value.
      I have for 13 years, avoiding expat buisneses is the best advice i can give
      Indo is my main cruising ground and phuket my refit base by default.
      Yes youre right about the o rings. My plan is every 2 years to remove and clean the core and replace the o rings. This issue was the only issue i ever had with the motor and had i known better i would have serviced it.
      This issue yanmar said is common. So yanmar owners beware.
      Also that cap end can only go on one way. I spent days trying to figure out why i still had a leak. So that rear cap looks the same either way but its not. Finally i figured that out.
      I feel for you looking at all those blisters. Its no big deal i know but its a lot of hard work. Looks like youre right into it now.
      Good luck.

      Marcel, for a long time I had been slathering LanoCoat, a lanolin, onto the whole stainless steel clamp and especially the tightening screws. The clamps still rusted, especially around the screw area. I would pay for titanium hose clamps but the one company I contacted was not responsive and Allied Titanium, my chain plate supplier, does not make Ti hose clamps. So I try to keep a big supply of new clamps on board. But I first check the clamps with a magnet before I buy them at the store to make sure they are all stainless....but sometimes I have to go with what is available.

    I'd call that a lovely surprise. Nothing more satisfying to find a definite disaster waiting to happen .... and then prevent it. That corroded elbow could have fallen apart in your hand a 1000 miles out. Fixing that was a bargain at any cost. Beautiful job on the riser BtW.
    You did a good thing with the hose clamp positioning it at the very end of the hose. So if the hose splits at the edge of the clamp (in the future) you get a chance of a 2nd go by moving the clamp a little further up the tube (get you home measure).
    It's been years (decades) since i stripped an engine, but somebody once did once tell me that it doesn't hurt to put manifold bolts back in the same holes.
    Lastly gaskets are there for a number of reasons, one that you touched on elsewhere. They can keep the metals apart.
    OK this time lastly, really. Have you ever considered rigging the engine cooling as an emergency bilge pump? I've heard of this but wouldn't know how it could be prepared. Maybe you're thinking of how that might work, right now.
    Probably better on just sea in sea out cooling.

      Thanks for your comment. It would not be hard to rig the engine to suck bilge water by putting a Y valve between the engine and raw water strainer. It would be my luck, in such a situation, the bilge would be sucked dry and at the same time I'd be so distracted with whatever emergency was going on, the engine would burn up from lack of water. It is an option though. We have 3 bilge pumps. The main pump then the emergency electric bilge pump which never touches water unless it should get very high in the bilge then the very high capacity manual pump. Hmmmm, rather than installing a Y valve, I will take a look at the hose on the raw water strainer and maybe set up what could be a hose extension which could plug into the raw water hose after ripping it off the raw water strainer. Thanks for the idea.

    Nice work on your part, but I was a little surprised that the rebuild shop did not clean and paint your exchanger more than they did. I have always seen that type of thing come back looking like brand new. Also, that bolt you put in to support the upper rad hose looks like it may rub its way through over time.

      That would have a nice touch to have had the exchanger painted upon pickup. Online somewhere, a person said that a rebuild, such as I had done, would cost, in the U.S., 75% of the cost of a new unit. I would think the same would be true in Australia. So, for $250, I am satisfied. To protect the discharge hose from the new hanger, there is a cut open piece of clear water hose separating the discharge hose from the bolt and the ties securing things. It is hard to see in the video. Thanks for your comment.

      In these radiator repair shops, apparently it isn't too big of a deal to build up the deteriorated metal by welding, brazing, or whatever, then milling back the desired shape. They also checked the copper tubes and soldered some thin areas. It would have been costly to have this work done in Australia or the U.S., but in many of these foreign countries, labor cost is a fraction of what it is in the bigger economy countries. I also hope it does not leak. We are still working on rebuilding the exterior resin blisters on the hull so it will be months before we are back in the water and really give the heat exchanger a good workout .

    Patrick, You set a high standard for us diy'ers. I have a problem with my goggles fogging up when wearing them with my 3m respirator. Do you have a similar problem when you are suited up? What respirator do you use? Is it good for paint like Perfection 2 part polly as well as particulate matter like the asbestos?
    On another matter, my boat had a small leak on a brass drainage hole in the transom. It has caused the plywood core on the transom to rot a little. The transom is still strong and the fiberglass is in perfect condition. I was going to fix it by getting some gitrot and pouring it into the layers between the two fiberglass sections and then fill the void with some West System Six10 Thickend Epoxy Adhesive. What do you think of this attempt at repair? After the void is filled I was going to use a nylon drain instead of brass because I think it will hold up better.

    • @SailingBrickHouse-RVLife
      @SailingBrickHouse-RVLife  4 ปีที่แล้ว

      If your goggles are fogging up, air is escaping from the respirator and not going out the discharge at the bottom. Check the one way valve and see if it is stuck. That thin piece of rubber disc often gets stuck to its surroundings inside the respirator. I have a very good dual filter respirator and a cheaper single filter respirator. The dual is far better for all reasons but I have dedicated that one to my helper named Sip. I don't like the idea of sharing respirators.
      You would have to check the specifications of your respirator to see what it is good for filtering. Painting the inside of our aluminum water tanks, it would have been impossible to paint them with 2 part paint using only a respirator, without burning out some brain cells. There I used the pumped in air from a hookah to breathe. Out doors, I would use a good, properly rated respirator.
      Forget, GitRot. The wood is rotted because it became saturated with moisture. Pouring something into or onto wet, rotted wood, does nothing. The GitRot will stay but the wood continues to rot. A heat fan, like a hair dryer, would have to completely dry the area first and that can take days, if not weeks. If you have the right tools, it is actually faster, better, stronger to remove the deteriorated wood and rebuild the area. Can you drill down or some how dig out the deteriorated wood without opening the fiberglass skin to gain access?

      I second that suggestion by Patrick. Remove all the wet, rotten wood. Then rebuild. I just finished removing rot from a section in cabin wall coring. A Portlight was leaking water into the balsa core of the cabin wall. I drilled “exploratory” holes into the wall after removing paneling to discover the the parameter of the problem. When the drill bit comes out with wet soggy wood you know you’ve struck rot. I drilled about 20 holes to determine the perimeter. Then drew a square around the affected area and used a Fein tool to cut the fiberglass skin. Then used a chisel and hammer to pry the skin off revealing the rotten core. Hammer and chisel to remove rot. Then shaped some plywood into missing core and glasses back in with thickened peanut butter epoxy. Of note is I first coated and sealed the plywood with epoxy for better adhesion. Hope this helps!

Basic workers get around $12 a day but "things" like clothes and tools are not cheap. There is a 58% import duty on most things so there are few bargains. I just paid $60 for a liter of two part polyurethane varnish. Nearly all marine supplies are imported from the U.S.. Africa is fun though and in many ways nice and modern. Certainly not like Somalia or the other miserable African countries far to the north. We just got back from doing a visa run to Namibia.

    Hi Patrick. Great videos - lots of work you guys doing. I also have the same Yanmar 4JH3E (new 2004) in our sailboat. Have you had any seawater leaks from the small oil heat exchanger ? (the small heat exchanger located aft end of motor just above and forward of the bell housing/gearbox joint area that the sea water pumps through first before the main heat exchanger) My Yanmar's oil heat exchanger has some slight corrosion now visible... with what appears to be a few rusty spots just under it from what I assume is the result of small drops of seawater in the area. I have not observed any leaks (ie drops) but it must be leaking a very small amount now. Adding it to my coming 2019/20 winter maintenance here in Vancouver BC to drain oil and investigate this.
    Keep up the videos.

      There are two oil coolers in that area, the main engine oil cooler, far forward, and the transmission oil cooler. The first one in line from the raw water strainer, which is the transmission oil cooler, never showed any leaks on the outside. On the inside core, there was a very slight leak which allowed sea water into the transmission fluid. Good thing I had plenty of transmission fluid on board, to keep changing, till we got to a place to rebuild the core and for us to order a new cooler. So now we have the rebuilt one as a spare. Good thing you are catching your drip early on.

      Bruce, I will give a little response as Rebecca said most. There are places where some people work hard to scratch whatever they can from what little resources are available. A good example is Paul, in Russian Bay, Madagascar. By our standards, he is very poor but lives in a hut on a water front hillside. That is a nice piece of property. But Paul, with the help of a previous cruiser, put together a photo album of his guided, walking, tours across the island and sailing on his wooden dhow. We have hiked hundreds of islands and seen countless waterfalls and really had no interest in doing all this again. But Paul was really trying to work, where there was no work, so we signed up for his island tour and boat ride. It was a fun day, and lunch, with a local. The sail on his "charter boat" was a great experience also. Here in S. Africa, unemployment is very high. In just about any shopping mall parking lot, locals will show up with an orange vest and stake out a parking area. They are now the parking attendant. They help point a driver to a vacant spot, help clear shopping baskets out of the way and help direct a car as it backs up, out of a parking space, to help avoid a collision. The attendant accepts whatever the drives will drop into their hand. Normally the tip is around 14 cents. This service is not needed and could seem annoying at times but these people have absolutely no other work to go to, but they are doing something other than standing on a sidewalk with their hand out. I always give them a good tip. While parked, someone else will have a bucket of water and you can get your car washed for cheap. How fortunate we were to have been born in the U.S. or for others in a European country where education is mandatory and free. .
