- I'm really happy with the progress on Seeker's tender. She is just unusual enough for my taste. I wish more people built boats, but I wish those that do build boats would do something a little more unusual more often. There is little to nothing to learn from building from stock plans. Don’t be afraid of picking up a piece of cardboard and start cutting and gluing until you have a model that you believe will suite your requirements. You do not have to be a naval architect to know that the water needs to stay outside. Go ahead and try it. --Doug

Waiting for more videos. Can't wait. I was talking to my oldest son today. He was telling me about this guy on RUclips who was actually building a 74 foot ship in his yard. I told him, " I know, I have been following him too." Keep it up.
Rendering it now. :) Thanks for following along.
ALWAYS A LEARNING EXPERINCE JUST BY WATCHING AND SOAKING IN THE KNOWLEDGE AND INGENUITY!!
Painters minds have been blown by SV Seekers WELDING TAPE!!!
I marinized a Volvo d5. I used a 2" exhaust with two sharp turns. The cooling water was added right after the turbo. The back pressure pushed exhaust back into the water cooling and the engine overheated. Blew the head gasket and cylinder head was bent like a banana. Went to the scrap yard and got a new engine and beefed the exhaust up to 3.5" and used a hose to get a smooth path for the gasses. No problems since.
Old rigger shared with me his Kano Aerokroil that no one can get but I've always used the Blaster which isn't as expensive. Enjoyed watching Steve do his thing in Georgia. Pretty resilient guy but loved his wood working equiptment :)
I hate finding these series half way through. I'm dieing to see the tender on the water already!
My dad was a machinist. Drilling, milling and lathe. He would sometimes do 50,000 of the same small metal or plastic parts, to be used in other machines. His slogan was, “They might not be right. But at least they’re all the same!”
Live Oak - that was a great video! And those contraptions... like no other - Great!
Doug, Very clever install of the VW Diesel.
Please note that it is essential that the turbo be allowed to breathe. The exhaust needs to be as open (large) and unobstructed as possible. Otherwise you will literally "stall" the airflow and obtain less boost. The air intake cooler is a fine idea but the exhaust has to support full flow first.
All the best,
Eric
Progress progress progress. The team doing great. I love the journey the passion the companionship and the madness. Keep it up
I think you're really going to enjoy that Professional machine. It saves a lot of time on Zig Zag work for sails because it does that 4 point instead of the traditional two. I still have my LSZ-1 and got the fabricator because I coudln't justify the 5 grand just yet, but I took a spin on a Professional and loved it. I replaced the silly big gray treadle peddle and knee lift for the foot with two of the shoe shaped black feet from the Professional and that was a solid upgrade.
Yeah, it's crazy to watch it do that stitch.
Hey Doug, These VW diesel engines were notorious for breaking exhausts. the steel mesh pipe at 7:32 was a good fix. they would always crack the pipes pretty close downstream from the exhaust manifold no matter how well you had the pipe hung with rubber bushings etc....something you may want to think about is a couple easy flanges to unbolt so it can be quickly pulled out and fixed
Ive never owned an ocean going vessel, only fresh water boats. None of them ever had an air filter, only ever a bug screen or mesh type intake cover. I asked a marine mechanic about it once. He replied 'when was the last time you kicked up dust on the water?'
I have lived on this coast: images.spaceref.com/modis/image05052012_500m.jpg
SV Seeker thanks for the replies! Also whenever I salvage parts for a build I jot filters #'s, make/model of donor, etc in a book or write the make/model under the lid of the housing. It helps when servicing. Thumbs up again Doug!
Lets not forget this is the tender. It will be going ashore often and there will be plenty of dust and dirt blowing around on the beach.
They want to sell you new engines in 3 years?
Even if you don't need an air filter that just means you'll never need to change the air filter
AvE has done some tests on rusted nuts and penetrating oils. During the tests, percussive action applied to the fasteners made the greatest difference and was not even intended when it was discovered. Old fishy WD-40 was the best bang for the buck, but I am not sure how that converts from Cunuckistan kopecks and beaver pelts to US$. For the most part though, it looked like the data showed similar performance across most of the oils.
Of course, a little physics with differential heating helps a lot too, as you no doubt know.
Science and Humor. That is what I love about AVE. I really think the snake oil is best for giving you a prettier flame while heating it up with a torch.
And don't forget that lovely smell of burning petroleum distillates. Smells like mechanical work.
Gotta go with da dubbya-dee! When she goes, she goes.
I did some statistics from his last one and found that the penetrant itself reduces the variation in loosening torque but statistically does fuck all. The tappe tap tap however did reduce it. I hope he runs an experiment with that and fire and a combination so I can do interaction plots.
That thumbnail makes me imagine him sitting there making boat noises and bouncing up and down.
I also use CAD exclusively during my fabrication projects... Cardboard Aided Design...
Doug and crew-Another great video! Love the looks of the tender and can hardly wait to see it in action. Take care and keep on moving' on.
Yeah! I just watched that video about the white oak boat repair. Pretty cool way to cut lumber.
Hi as a suggestion I live in baja on sea of Cortez and I learn the sun kill plastic, rubber , elastic, a cover for the tender will save it
Keep the good work and the mojo .
If you put graphite anti-seize on the exhaust bolts it would put a protective film on them so it doesn't rust. I would coat entire bolt so it also wont brake in the holes. Project looks cool
ain't it funny how things change! if I'd have gotten all excited about a Sewing Machine as a Christmas/Birthday Present back in the day, my parents would have been a little concerned! lol - however these days I get your enthusiasm, good engineering is good engineering at the end of the day I guess. Great Upload Doug/Betsy.
Well as long as its got good torque thats all that really matters eh Doug?!
Watching SV Seeker being built from the bare bones up is all the nudity any guy ought to require - there's raw sex right there.
If you're going to install the intercooler, you'll have to run another keel cooler to supply clean cold fluid to the intercooler. Never, ever use sea water it'll either corrode the intercooler and/or get plugged up with seaweed etc. Plus don't forget a lot of sacrificial anodes to avoid corrosion to the hull.
The Georgia lumber cutting on Sampson boat Company was really interesting.
Great decision to use the sailcloth, looks great!! :D
hey good intro, good for newcomers and feels more cohesive as a ''series''
Oh Ship, I was in Stilllwater a few days ago and it was raining and I totally forgot to come over and lend a Hand . Weld , Fabricate, Engines, etc . Used to build Trawlers.. Be back again soon To see Family. all the way from Sunny Florida .
Your welcome to stop in for a tour on Saturdays, but to work you need to see this: www.svseeker.com/wp/sv-seeker-2/about-us/welcome-aboard/?v=7516fd43adaa
I guess I worry about hot salt water corrosion on the aluminum water lift muffler and exhaust pipe but we will see I guess. Don't forget to allow some sort of expansion and contraction for the exhaust pipe , even with the water cooling it will be very hot.
Loved the Simpson film , a real character and way less of Hill Billy than he appears! What an accent!
Cheers Warren.
You'll don't have to worry about that for about 10 years.
absolute great project and great channel!!!
Great progress! Thanks for the video.
Dear Doug, Amazing all the progress! Question: Do you ever wake up in the night and wonder/question if you can keep up with all the momentum this project has? Greetings from a big Fan
No. I wake up with an idea about how to build something.
“We do it right because we do it twice.” That was my family’s quote building are home at one point in time. Said around 12:00-12:15.
Love PB Blaster. Keep in stock all the time.
If you can, position that intercooler so that the condensation can flow out naturally. Water injection can be good thing, but uncontrolled splashes may be troublesome. Water standing in those cells will tax the surface area of that IC as well.
I did not see any flex pipe installed on that exhaust. Diesel engines have hella vibrations and you will have a broken pipe in no time...
Keep up the good work Doug!

Your decision to make the exhaust 90° bend a gradual radius is the right approach. You don't see trucks, cars etc with sharp 90° bends in exhaust pipes for the very reason that it creates too much back pressure. On any turbocharged engine the idea is to allow those exhaust gases to escape as easily as possible.
If you want to find out the best penetrating oil, check out Ave's series on them. Really informative and eye opening. Expensive doesn't always mean best.
With a turbo engine of any kind the less restriction you can have after the turbo the better. So making your exhaust flow well could give you some extra ponies. It's not going to make a huge difference in this application with low boost, but it will make some difference.
Thanks for the update Doug hope your taking vibration from the engine into consideration
fresh water only in that intercooler! btw it will only help during extended periods of full load over 14 PSI. For a boat where you could be pulling/pushing something at full throttle for a while it could come into play but again only if you are over 1 bar of boost.
Thanks
I like PB Blaster and AeroKroil, but I buy whatever's handy, too. Proximity to the door or checkout is a consideration. 😂
Have you thought about putting in a mesh flexible joint to make your curves on the exhaust? Same dohickys they have under a car to
let the exhaust flex a little to avoid fatigue.
Like it... Doug, have you thought about adding an air compressor to the engine? Now would be the time to reserve space for it, might be useful for filling bottles or anything alse.
i like using conventional motor oil on rusty bolts. paint them down at least a day in advance. one week is ideal.
i try to oil all the exterior bolt heads/nuts i can find on my vehicle.
also, petroleum jelly makes for a nice long term fluid film.
I love how you started the vid btw. That was a great intro.
That first intake is the same as the one I just pulled out of a Ford pickup yesterday.
Because I don't want to be laying on my deathbed saying I wish I would have..... you're awesome man
That is it exactly. And I have a lot of help from awesome crew that make it look easy.
think if you pull the paper around it and use a needle to pich through both layers of paper , then take the paper off and the holes will give you the schape the flat piece of vinyl needs to be without the tabs for stiching
it was a great video. thank you for sharing. Matt C.
The best penetrating oil I have used is a 50/50 mix of acetone and synthetic automatic transmission fluid.
Good video Doug! Let me think about air filter system of yours. Sorry I will have to say disagree with your install the air filter because for the one you never know when you are going to get flood inside your boat due to heavy rain, rough ride or whatever reason for your boat gets flood and the air filter suck up amount of water into your engine air flow system stalled and stuck in the middle of water. So I would have installed them in higher away from the bottom. Something to think about for safety reason and common sense.
If you want some killer penetrating oil, check out Kimball Midwest Torq "CB" part #80-744 this stuff is amazing. Just make sure it doesn't stay on your hands long. It will go through rubber gloves. Being a shop owner this stuff has saved me a lot of time. Blows Pb blaster out of the water. The test they showed me, they grab A Styrofoam cup full of water, then poured a cap full of their product in it, it went through the water and melted the bottom of the cup. If I have a spare I'll send you one.
Sea Foam brand "Deep Creep" compare it & it will be your favorite.
Check out AvE's recent video on penetrating lubricants. Surprisingly, PB Blaster did not perform too well when compared to WD40 and others.
AvE tested A whole mess of magic loosening solvents, and good ole' WD-40 came out a hands down winner in both effectiveness and cost.
Do install the intercooler asap, the AAZ engine will have high EGT even on a standard tune in a marine application, it's like going up hill in a car all day
mount the intercooler above the intake manifold so when it leaks it hydrolocks while cranking rather than sucking in water pooled in piping once running
running a few of those chinese air/water ICs and all of them leak very slowly
You make fun videos. By that I mean it looks like everyone is having fun and that increases the fun for the veiwer. Now my question. How are you cooling the motor? I see what looks like a radiator cap sticking up but I can't see anything else. A diesel with a turbo is pretty quiet so a muffler isn't really needed. Are you tapped into the jet for cooling water? I hope you are using some kind of heat exchanger for cooling. Raw water will eat the head gasket and any gaskets with metal that is not stainless. That's one exotic looking exhaust system. You will need a flexable coupling from the down pipe to the exhaust or cracking and vibration will occur.
Using a keel cooler. It's in the previous video. And the hose couplers will provide the flex
Great. I remember the keel cooler now. They always make me nervous because they are exposed to debris and objects in shallow water. In your case having an aluminum hull welding flat stock on edge along side the tubing for protection would be easy. Have you sloved the transport issue? I've seen some tractor trailer axels being worked on. Thats a challange I find very interesting and it looks like we are thinking along the same lines. Jamestown Distributers is offering a rust conversion formula to use before painting. I wonder if they might become a sponcer and supply the product in return for video and comentary that you do so well.
@ 17:56, the guy on the left is correct, what you are holding up is more constrictive than a 90 made from 2 45's...
hey Doug, i finally found the video for the exhaust cooling . just a quick question . are you not worried about the manifold being not cooled and just the down pipe being cooled ? i have currently the same system and find that the manifold generates a good amount of heat . thanks again! love the Tender its huge!
You're right, there is a lot of heat coming off the manifold and the trubo. We might build a water cooled manifold for it someday but for now we are going to add a fan and cut some vents.
Don't forget to do a egr delete on those 1.9 alh motors. It clogs the intake
Live oak not white oak, I love the guys Georgia accent. Y’all
thumbnail looks like something out of star wars / jetson,s hahahaa ,,love the videos
if youll be towing anything off a bridle with that jet, i'd mount the steering wheel so its axis is vertical
I got a aluminum fuel cell that would fit perfect in the bottom of that boat its a 50 gallon it is for a boat im not sure what boat it came out of it you can have it if you pay shipping
Thanks I appreciate the offer but the tanks are going in the rear for weight reasons.
50-50 atf and acetone works great
How many new tools have you made, Doug?
Maybe some anti-seize lubricant on the 1032 screws holding the The bumper material down?
Sure you will know about it but most jet skis use venturi effect from water exiting jet unit to suck water out of bilge, essentially a constantly running bilge pump with no moving parts. Just a tube that sticks into the jet nozzle.
I did not know that, but it makes sense. However I want something that works when we are sitting still and dragging wet nets and gear into the boat.
Hello Doug and Seeker crew. Love the vids,and the tender is coming along great! Just a couple of thoughts on the intake and exhaust. Marine engines usually don't have air filters. Gas powered engines do use flame arrestors though. Have you considered using a flex coupler in the exhaust for serviceabilty and to reduce the transmission of vibration created by the engine? If you need to fabricate motor mounts or isolators, hockey pucks work well. Looking forward to the next vid and sea trials for the tender.
I guess I've lived with dust storms too much so the filter is insurance, and the hose joints between the rigid pipe will give it a lot of flex. And I have never head of the flame arrestor being used. That sounds like a total kill joy. :)
I am not getting the "45 split in two 22.5" concept. Should you not consider the whole 90 and then take the number of cuts you want to make to achieve it? That is how you got to 90 = 2 x 45, (since 1 cut will have 2 pieces), right? So it stands to reason that 2 cuts will have 3 pieces and 90 = 3 x 30 .... maybe it's just me, but I keep missing out on 1 of your 22.5's ....
Cut at 22.5, rotate one side 22.5 = 45 degree turn. Cut it again at 22.5 and make another 45 degree turn. Two cuts, 3 pieces, 4 - 22.5 degree angles.
Love this project. Great video. So much going on! :-) I also reckon good old WD40 takes some beating!
How strong is the foam/flotation thing? Because everyone is going to step in ir gerting in and out of the tender
Mighty car mods use tape to make exhausts. I'm sure they borrowed it from someone else though
You should divide the total turn of 90 degrees, divide that by three, equals 30 degrees.
No. Look at it again.
Bart is a regular Vana White
thanks
most junk yard drill holes in things like fuel tanks to drain them
Just an observation, cover the bumper material before you burn holes in it from welding near it.
The EPS foam as well.
Around 20:00, Sorry you aren't the first. I've done it (Not exhaust pipe, but tape!)
Молодцы!!!!
He's famous now
Why don’t you braze or solder them pipes together do it’s clean and no pin holes?
crc 5.56 is what i use as a penetrant.
mig welding with an additional rod I heard called texas tig in a muffler shop
Looking good
when the sailcloth fails, layup kevlar with epoxy resin in it's place and it will last for several lifetimes.
I think your hooked on Ross at "life on the mould"
Maybe you could try some fibreglass work.
Cheers from Niagara
We'll build fiberglass sewer tanks. :)
Don't forget to bring the sail makers sewing machine when you go. A: you can fix your own sails, and B: you can make money/trade fixing other peoples sails.
I think I've seen that landspeeder in Star Wars
That container trailer where did you find it at .. I am looking for a 20 footer ... Thanks .... She is looking good
It was in a salvage yard.
Great video, I suggest raspberry for the painters tape smell idea - patent anyone ?
Do the gradual turn on the exhaust!!! The 90 will choke you off! Ask me how I know........
U should've wrapped the fabric around the flat bar on the foam wrap
I considered that but I don't think it's a good idea as it would trap water and aluminum does not like stagnant moisture.
Hey Doug, love your work and your build. I’m wondering what foam you used for the tender and where you got it from? I’m hoping to do similar to a tender that I have. I read on your website that it is rigid foam. I presume it won’t crumble under impact and it has some sort of absorption. Can you please elaborate? Thank you again and love your videos!
Most of it came out from under old docks. They have banned foam on a lot of the lakes so when they rebuild a dock they have to remove it. That foam is 1 lb per cubic foot. The foam in the bow is left over from out dragon sculptures and that is 2 pound per cubic foot. Hit it hard enough and it stays dented but when it gets too bad, it's simple to cut the damaged spot out and glue on a new piece.
SV Seeker, thanks Doug! I will have a hunt around here for some old jetty or pontoon foam. We’re in Perth, Western Australia, so not too much of that stuff around here. You have a little fan base over here by the way!
Thanks again!
Don't put a 90 degree angle on the exhaust, it will affect fuel efficiency and power at least some what.
I don't think you'd notice. ruclips.net/video/azPKIjxmmdU/видео.html
That's actually quite interesting.
Avtually those are 10-32 button head screws.
Please tell me that the post being used for an air intake also has a hole at the bottom to allow water out?! I think it's not a great idea to pull air from an enclosed space like that, lest it suck up water. If it were me, I'd have an upside down p-trap on the inlet of that airbox.
Have you ever seen a four-wheel-drive truck cross river? Have you ever seen a boat filled with water still running?
Im a little bit concerned about that "cloth". I dont think its gonna last for more than 6 months. Hope Im wrong.
I'm not concerned at all. If we tear it, we can fix it.
Yeah! I get the Spirit! And I like that. It's just that I'm from Switzerland and when we make something, it has to last for 100 years... But, I'm not gonna last that long anyways... My bad... +1
Well were is water big nuff for that Giant ship in the yard
impact bumpers for the outside of the floats?
