Thanks for watching. If you have and comments or questions - don't hesitate to ask. Blaine answers them every morning!

Dudes. Spend 15 mins at the end of each day and clean and organize your workspace you will find that it will speed up work the next day twice as fast and not aggravating. I am the same way but now that I do this things are way more professional.

@OnboardTangaroa 24 дня назад

Over all my years doing this kind of work I have come to accept that this is just how I am. I have unsuccessfully tried to change many times so I have instead learned to work around it. The end result ends up being just as good for me. Thanks for watching!

@billymiller9991 24 дня назад

You two are very talented watching Blaine design the fuel systems and just the clean setup on the wall really awesome to watch plus it’s quite entertaining lol great work guys

@williamhamill813 24 дня назад

@@OnboardTangaroa It is not like you are doing it professionally so whatever.

@OnboardTangaroa 23 дня назад

I work this way on very nice cars professionally and I have a waiting list so they don't seem mind either. As long as the end result is the same it really doesn't matter how you get there.

@johnschieffelin3226 23 дня назад

Lots of technical know-how and skill required.

@OnboardTangaroa 23 дня назад

Some of it for sure. Other stuff just needs creative thinking and problem solving. There are typically multiple ways to do things and some may work better for one person than they do for others. I am fortunate to have a background that has been ideal for this project. Thanks for watching!

Yalls boatyards are way different than ours in the states. Yall seem like nobody bothers yall for anything and yall can actually work on yalls boat. Here in the states the only way that would happen is if u pay them to do the work. Other than that u have to take ur boat out and onto ur own property so kuddos to yall for being able to do so in yalls boatyard. I know its a pain either way not only living in a boat but actually working out of one as well. U will eventually get it all organized and the way yall want it. But once its complete which it will never be 😂😂😂 it will be all worth the work and cant wait to go along with u guys on yalls journey. I promise this is the last comment for me on this video. 😂😂😂 much love to you guys from Maryland❤❤❤.

@OnboardTangaroa 23 дня назад

We are very fortunately to have yards like Steveston around us. I know in a lot of places the yards are like you describe. Steveston is a municipal owned yard that's there to help subsidize the fishing fleet so they aren't as money hungry as business owned yards. Even the day rates are massively less than other yards. No worries about the comments. We read and respond to the all.

@jamieallport7106 19 дней назад

Blane i would love to have your level of knowledge on all things mechanical and electrical. I know you are a marine mechanic/engineer. But i can't imagine how much extra it would cost to pay for the experience and man hours to do the refit on your boat, if you were paying someone else to do it. Much respect sir, and love the channel.

@OnboardTangaroa 19 дней назад

Thanks for the compliment! We regularly discuss how much money we would be spending if we didn't do almost everything ourselves. I doubt we would own this boat for sure. We are definitely not perfect though. There are plenty of things I end up redoing as I am not happy with it. Thanks for watching!

The clear hose is food and beverage line it was very common to use it. Stuff was cheap, heck of a lot cheaper than black fuel hose. The fuel system is a little mind boggling. That is a lot of valves and manifolds you'd definately would want to have things labeled. When an oh sh*t moment is happening gotta know which valve does what. A person can look at that and say it could have been done differently. When your designing something in your head you have to do it yourself. Check off the boxes in your head okay that one is done. Im a little sceptical on the push to connect fittings. Heat cycles stuff is going to get loose over time. I'm a bit old school, prefer stainless band clamps. Yes you need the tool to make the connections. Its like sharkbite plumbing fittings don't really trust them either. Everything has become push to connect especially in the automotive world. So that tank you guys moved the day tank? The old 12v71s would have sucked that dry in a few hours. The 6.7 Cummins there can't be that much fuel return. I assume the engines have a valve to keep the rail pressure where it needs to be. If you ever had a vacuum happen on the return side it could drop your rail pressure. Keeping fuel clean is the utmost importance now you have engines with tighter tolerances fuel systems. The old green grenades would burn anything. They sure don't like air in the fuel system. Your there shooting the cosby sauce in the intake praying the pump will pick up the fuel. You hope the batteries have enough juice the starter is hot enough to cook an egg on it 😂

@OnboardTangaroa 23 дня назад

I hated that food grade hose. That stuff terrified me. The fuel system looks like a lot but its actually fairly simple. The top two manifolds are supply and return for the transfer/polishing system and the bottom two are supply and return for the engines/generators. We just have a lot of tanks.I will eventually make up some nice label placards but for the time being, sharpie it is! The pushlok fittings are a bit daunting at first but I use them lots at my shop and have had really good success with them. I believe the tank you are referring to is the little plastic tank on the aft deck? If so, that one is a water tank. The day tanks are 200 gallon aluminum tanks down in the engine room. They lasted a good while even with the Detroits as we didn't push them very hard. Surprisingly the Cummins actually move a fair bit of return fuel. Those CP3 pumps work well. The rail pressure is actually controlled by a valve that controls the suction side of the pump. Seems to maintain pressure very well. The Cummins do take a bit to build pressure if they suck air but I have some ideas to make a rapid bleeding system in the future. Thanks for watching!

@erichildebrandt9802 24 дня назад

Looking great

@OnboardTangaroa 23 дня назад

Thanks Eric! Should be back in the bay in a couple of weeks.

@jimmydaniel8752 24 дня назад

That boat would look awesome with that raw aluminum painted or need to grain the aluminum all one way if it stays raw

@OnboardTangaroa 24 дня назад

We wont be painting it again. Its too difficult to maintain paint on aluminum in a salty marine environment. Polishing it up a bit more is on the list but unfortunately its pretty far down in priority.

@kevind767 23 дня назад

Have to ask about the Tef Tape…….. AFAIK, Tef tape is a “BIG No No” with regard to with Diesel fuel fittings. Dope, or the appropriate Diesel sealant is the way to go. And I have heard that the Yellow Tef tape may work as well, as it is fuel resistant. The White Tape commonly used in plumbing, is not. It will break down, and contaminate the fuel system that you just so Painstakingly put together. P.S. I have not rewound this episode to see if you were using the Tef tape, but just wanted you to know. I am enjoying the rebuild of Tangarora, and wish you much luck.

@OnboardTangaroa 23 дня назад

Have no fear! The tef tape I used is the fuel compatible tape. I rarely ever use the plain white tape. So far that part has held up well. Glad you are enjoying the channel!

@matthewwelch9084 12 дней назад

What brand fuel line/fittings are you using? I’m getting ready to redo fuel system in my Grand Banks. Thanks. Great video.

@OnboardTangaroa 11 дней назад

I am using the Parker Wavemaster hose. It's coast guard approved and is a proper vapor barrier fuel hose. For fittings I am using the Parker push-lok fittings. They are super easy to install. Thanks for watching!

@melvinrawlings1457 23 дня назад

I would of def left that mast there and did what i had to do with it in place and let it eat and wish it well.😂😂😂

@OnboardTangaroa 23 дня назад

Janis just couldn't quite get behind it to grind off the paint. It was a necessary evil.

@JustinTurnerman 24 дня назад

Love the 1hr video guys . Blaine did you go to school to learn all these things on your guys boat or is it experience.

@OnboardTangaroa 24 дня назад

Glad you enjoyed it! Janis decided to try it out. I am trained and was licensed as an airframe and powerplant technician for aircraft originally. Immediately out of trade school (circa 1996) I was hired on as crew on the first yacht I worked on. After a brief stint as the first mate I moved to the engineer position and did that for six years over two boats. When Janis and I got married we moved to Victoria where I worked as a tech at a local boatyard for two years. I left there to work for the local cable company for five years then finally moved to my current occupation of owning my own performance automotive shop where I do a ton of custom fabrication, wiring, and engine swaps. I have been doing that for the last fourteen years and next year will be my final year with that. All-in-all its a mix of a lot of life experience backed with some great schooling that has got me to where I am today. I don't know everything but if something interests me I absorb info like a sponge.

@JustinTurnerman 24 дня назад

@OnboardTangaroa awesome. Experience is how I learn best. Once u do it a few times, it tends to stick and you find the best way to do something that works for you. Great video Janice. Thanks for the reply Blaine.

@OnboardTangaroa 23 дня назад

No prob at all. I try to reply to every comment. May just take a day or two.

@JustinTurnerman 23 дня назад

@OnboardTangaroa I think it might get alot harder once you guys are up over the 100k subs mark haha.

@OnboardTangaroa 23 дня назад

We will see how it goes. Never know how people will take to a channel. We will just keep doing what we are doing and see where it takes us.

@JustinTurnerman 24 дня назад

That wood might be Birch.

@OnboardTangaroa 24 дня назад

Could be. We met a local shipwright at the yard an we just went with what he said 😁. I leave the wood stuff to the woodies!

@kenmcdonald7793 24 дня назад

Just wondering... With the "smaller" engines would one muffler have managed the exhaust flow?

@OnboardTangaroa 24 дня назад

Unfortunately using one muffler with two engines will not work as if one engine is shut down the exhaust from the running engine could path back through the shut down engine and exit out the air filter into the engine room. Would be nice to not have to have two mufflers though!

@deuteronimus750 24 дня назад

Who made your boat?

@OnboardTangaroa 24 дня назад

She was built by Stevens Brothers in Stockton, California in 1969.

@rogerreed905 24 дня назад

Are you looking at starlink at all ??

@OnboardTangaroa 23 дня назад

We have Starlink already. It has been a very good addition when we are out of reception range for everything else.

@jimmydaniel8752 24 дня назад

Before u weld always wipe it with acetone

@OnboardTangaroa 24 дня назад

I always do, except for when I don't.

@mikej1097 24 дня назад

Did you leak test the fuel manifolds?

@OnboardTangaroa 24 дня назад

I did not really have a feasible way to leak test them. They have been installed for a bit now and do have leaks however none of the leaks are from where I would have expected them. We will cover that in a later video. Thanks for watching!

@melvinrawlings1457 23 дня назад

Should of did that board cutting and all that for the exhaust before she painted it and all. Got to work on yalls organizational skills for your projects so ur not taking 1 step forward and 3 steps backward. But yall def get shit done though. Great job once again.

@OnboardTangaroa 23 дня назад

I just totally forgot I had to cut that board is all. My brain was already pretty fried by that point.😄

@1798iscomingback 24 дня назад

With smaller displacement engines, can't you get smaller mufflers?

@OnboardTangaroa 24 дня назад

You can indeed but marine silencers are ridiculously expensive. We already had these and they don't really take up any usable space. With an unlimited budget we certainly would have replaced them but alas it was not in the cards on this refit. Thanks for watching!

@mikej1097 24 дня назад

That turbo compressor wheel hanging out unprotected makes me nervous.

@OnboardTangaroa 24 дня назад

Unfortunately I had to do some fitment and there was clearance issues with the compressor housings. No compressor wheels were harmed in the making of this video. 😁

@jimmydaniel8752 24 дня назад

Lol how do u guys find anything it looks like a organized mess lol wow

@OnboardTangaroa 24 дня назад

I have long since come to accept that this is just the way I am and have learned to work around it. 🤣
