Twin 671TA boat detroit diesel trip to VA day 2

Day 2 in VA at a marina to work on a boat with twin TA inline 671’s 450+hp each. 238 hp is a stock 671. One did run away and the other i got running yesterday.

Now that I watch your videos I look at all the buses that pass on the road . Never gave it a thought before

[@billchapel5248]

Back in the early 80s, i drove truck for a while, out of the three different ones i drove, they all had the Detroit 8v71in them, i just loved the sound of them, until i drove it all day, then all i could here in my head at night was that Detroit screaming in my head its been many years sense i drove those old Detroit, i really miss them.

[@OBS_Ford_Diesels_Inc]

Nice to see someone who really understands these old Detroits and can get them running with no big problems. Nice work as always.

[@phooesnax]

Don’t own a boat, a diesel, a bus BUT I love this stuff. Thank You !

[@slyguyaction]

phooesnax Me too!

[@scottkasper6378]

“Don’t own a boat” is good advice😂

[@axeman6560]

That one sounds good too. This owner will be stoked to get her out of dock! There's nothing like the sound of marine Detroits howling.

[@buenaventuralife]

Scott did great things here. Methodical when analyzing the engines - before touching them. The best thing about getting the port engine running is that it was the one considered damaaged. Just the injector.

[@Jethrosgarage]

Ahh, a mid to late 80's Ocean. The Bayliner of big boats. Having been a marine diesel tech since the late 80's I can tell you there are tons of boats that age rotting away in marinas all over. The maintenance to keep one of those seaworthy is astounding. From it's looks, that boat has been neglected a loooong time. Bet the "fuel" in those steel tanks is black sludge. The cooling system on those J&T's is likely full of barnacles, and lord knows how many bolts will possibly snap off in the process trying to get them apart! Back then, you had so many distributors and dealers taking a Detroit industrial engine and marinizing it to their own package. Thus there are parts unique to the marinization that may or may no longer be available! I know you had Stewart and Stevenson, Johnson and Towers, United Engines and who knows who else was doing their own unique mods. So thirty some years later there are boats out there that have parts and let's say changes made to blower drives etc that no body knows about. And now the boats, once shiny prize possessions of well off folk, are in the hands of folks who really don't have the money to make them run right, and are too cheap to pay somebody with the knowledge to actually make the thing right! That boat is kind of like buying a 1987 Ferrari... needs lots of love and lots of money and the skills very few have.

[@siaripop7]

When that engine finally started it ran amazingly smooth at low RPM's...impressive!

[@makeitwork583]

Marc Del check out Deboss Garage. They do a 16 cylinder 2 stroke runaway, good stuff!

[@jgriff3218]

Thank you for the shot of the back of the boat. Sounded so great. Brings back memories

[@Shane-Singleton]

Another pair of Detroits lives again! Nice work as always. That vendor got that injector to you fast!

[@1320fastback]

Love that heavy duty engines have serviceable starters. Save so much money and get to keep your OE high quality part.

[@justjackfromsc]

Thanks for the video. I really enjoy learning about the diesels from you. You have a ton of knowledge and I like how you present the material. God bless.

[@lutemule]

This channel is becoming one of my favorites!

[@AustenARW]

Mine too!

[@cbmech2563]

A boat is what a 6 71 was designed to be in. Bring them up to rpm and leave them. Ever seen the power heads they use on work barges? An outboard motor with a 6 71. A guy who worked for Valley Detroit in Fresno CA. Had most of the 1937 engineering notes and drawings from the Louisiana testing. He was also one of the trainers when I took a 650 Allison rebuild class in 1985.

[@davidhollfelder9940]

Great stuff .. I don’t own a bus, diesel or a boat, but, karma will call at some point .. (like the vice grips on the fuel rack .. and checking for seized injectors) .. in my travels, one day I’ll be tasked with working on an old diesel. I’m an advanced DIY mechanic, fly turbine powered model jets .. this is also right up my alley.

[@bbrut3332]

Good going two running and burning. Just what we expect from the classic diesel mechanic. Good find on the starter bendix ring.

[@daverayasr.6287]

Always leave us wanting more! Can't wait to hear them purring in unison! I'm a patreon now, not much but it's the least I can do for all of the knowledge you have shared!

[@AustenARW]

Man, the exhaust sounded great from the outside! Totally different tone from a boat compared to the same engine being in a vehicle; what a rumble when it first fired off, he he. Hope you're able to film more outside footage from the back when you get both of them running. Thanks for taking us on all your adventures. This is great fun to follow!

[@larrygall5831]

Man I love these videos. I used to work on cars a lot when I was younger, but never diesels. I always had a fascination with buses for some reason, and when I seen videos about bus mechanics I clicked right away. This is likely the 20th video I watched and am loving this very much. Thanks for uploading this stuff. You have the right personality for it, too.

[@kwil3330]

Had a pair of 8v92T's in my grandparents Chris Craft....Guy bought the boat for the motors. They were so much fun to listen to....Many fun summers on the Chesapeake with that ol boat

[@johnfenn]

The second engine sounded sweeter than the first.

[@johnfenn]

@jason9022 No I am a complete ignoramus.

[@1982MCI]

Damn it Scott, that thing sounds fricken awesome buddy, well done man!!!! I’ve gotta set up patreon account with you, your the only one I’ve found worthy yet!!

[@TUMBLINJEST]

I`ve been losing sleep over this one..lol, no, love your videos, and glad that yet again your there to fix problems so you can say - yep, thats another one fixed.......Waiting for your (our) next adventure - thanks, from coastal North Essex UK.

[@bnkwupt]

Hey, they both run! Well done ... enjoying the boat stuff in addition to the bus stuff.

[@BusGreaseMonkey]

And the boat is still floating contrary to some naysayers yesterday. Check out my Instagram post today. Smoke on the water detroit diesel style

[@phantom629]

Something very relaxing about the sound of those old diesels

[@dans_Learning_Curve]

Seen the pitted starter solenoid disk and contacts a few times. Great work! Great sound when those beasts fire up!

[@oldfarmer4700]

The first Detroit I ever heard or seen was a brand new Fleetstar 2000 with a 671 my second cousin bought after he got out of the army back in the early 60's. He hauled grain to the twin cities and now he owns a trucking company and about thirty trucks and many different trailers. I thought that 671 was the cats meow.

[@GRADE8BOLT]

Never got on the asphalt with a two stroke but I ran a Terex pan with two 4/71 s front and back

[@michigandon]

I ran a Bomag compactor that was powered by either a 4/71 or a 4/53, can't remember which, back in the '80s.

[@garyrobinson8991]

Not a Greyhound, but still very entertaining ! Great stuff !

[@grosseileracingteam]

I've used a hammer on GM engines, but I've never seen anyone use a screwdriver to check for spark on a Detroit. ;-]

[@fillg]

Ah yes, the old "hit it with a hammer" trick. I use it frequently on everything from cars to computers. :)

[@jw4620]

Of course it runs! I got my T shirt today!

[@bitzaboat]

That is one of the best sounding engines I ever heard on a boat!

[@timnorris5891]

Really enjoy your post. Grew up having a 54 bus that we had to going around the country in. Great memories

i was in a truck shop 40 plus years ago the mechanic had replaced an injector on a 6-71. started it up had it start winding up. grabbed a piece of plywood put it up to air intake. motor stopped. left a nice imprint on the plywood. me i ran for the exit

[@bulkchart3239]

the old hammer on a starter trick. i used to keep a hammer on the front seat of a honda accord. i eventually had to upgrade to a steel mallet. like my old boss at the tractor shop said, "the 1st rule in mechanic-ing is: when all else fails, get a bigger hammer".

[@BusGreaseMonkey]

I got a little hammer.

They are called "tune up hammers"; most mechanics carry a selection.

[@jackbaker5284]

@@BusGreaseMonkey I see. Thanks for the get back! Were you ever able to determine which engine had been recently rebuilt as the rumor was mentioned? Thanks again...Jack

[@ratman5727]

Probably after running away it hit who knows how many RPM's, -it is probably "lightly massaged" ;-)

[@buenaventuralife]

Looking at the marks on the head bolts, rocker arms and springs, we are sure the starboard engine had the head worked on. There are no indications that the engine was rebuilt in place. Also, it had no water in the fuel.@@jackbaker5284

[@USMMCE]

Anytime that we had a run away on a 71 series, we had to replace the Blower Seals.

[@ShainAndrews]

Good stuff mate. Never would have guessed a marine injector would come from Wyo. Afton no less.

[@BusGreaseMonkey]

Those guys are great.

[@4321grp]

Good job getting it going, I wish you would have had both engines running together in the video

[@96chevydually6.5L]

Success!

[@blampa]

Great video as usual, toward the end though there was no water flow which could mean blocked heat exchangers, destroyed impellers, rusted sea pump if it has a steel impeller or closed sea chest.

[@BusGreaseMonkey]

One step at a time. Yes that’s all probably crap. A diver inspected the bottom and confirmed nothing is blocked. Impellers are rubber. She has new ones and the heat exchangers need to most likely be pulled apart and cleaned at the least. Let’s just say she didn’t want to put new tires And rims on the boat before we knew the engines were in working order. We won’t run it long enough to heat anything up. Baby steps.

[@blampa]

Bus Grease Monkey thanks for your reply which makes perfect sense. You sir are the Detroit whisperer, I just love how you coaxed both of those engines back to life. We just serviced an 88 foot Pershing with twin V16 quad turbo engines. 102 litres of low SAPS oil in each - all pumped in by hand in 20 litre drums due to EPA regulations. Stick with buses; boats hurt the body too much.

[@cobrasvt347]

They sound perfect. What beasts of a engine. Wonder how much horsepower those injectors that are in them are allowing it to produce. The M's are 450, do you think someone has changed them out from what came in them and it's just a mis lable or what do u think?

[@enginefreak454]

Looks like they were in drive

[@WallStreet749]

You need a pair of 2 way radios

[@captsam54]

Good Job.. we sometimes had to stick a big Craftsman across the solenoid to get the starter to work. .. lol. but you have to be quick and firm... Those deadman switches should be routed all the way to the pilot house or next to the start etc. switches.(looks like once they did), to kill it..(engine stop) cables. Still love those 671's.. .. Old Military Surplus now but still tons of parts.. I did learn something with your vicegrips on the rail.. Love your dedication.. And.... what is the new WIFI antenna you just got? thx.. Sam

[@BusGreaseMonkey]

They run up to the fly bridge for emergency shut down.

[@cravenrj]

Hi can’t wait for the test run on full chat will you guys use both engines together ,like your work thanks 🇬🇧🇺🇸👍

[@jeffnicks4909]

cool project did you do other work on the boat?

[@zackreuter6344]

Ah, the old hammer on the starter trick. It often works.

[@BusGreaseMonkey]

It failed me today but it’s about always a good effort, even if it’s just a stress reliever

[@mahatma171]

That second starter sounded tight.... then it just clicked. Ha....

[@bogiewheelman71]

That sea water is good for engine cooling ?

[@wallacegrommet9343]

Cautionary note! ULSD is less slippery than the diesel fuel of old. Add TCW3 two stroke oil or biodiesel at 1% ratio to the fuel to improve lubricity. Your high pressure pump will thank you.

[@Romans--bo7br]

Wallace G...... That's bad advice for these engines. They need to use FPPF Lubricity with fuel power in their fuel tank(s), was created specifically for marine use, as originally formulated. As far as.. "Your high pressure pump will thank you." goes, there is NO "high pressure fuel pump" on these (or Any 2 cycle GM/Detroit Diesel) engines.... all pressurization of the fuel takes place in the unit injectors, only.

[@wallacegrommet9343]

Never heard of FPPF. What is it? Both of the additives I mentioned reduced the wear scar on the HFRR test substantially, surpassing the EPA diesel fuel standard. Most diesel in the Pacific Northwest already contains biodiesel at a very low percentage as a lubricity additive.

[@BryanTorok]

Do you ever use a bore scope to look at the inside of the cylinders before turning them over? I've heard of people being concerned about rust or dirt damaging the bore, piston, or rings in an engine that has not been run in a long time. Your thoughts?

[@buenaventuralife]

There was no indication of rust inside the engines. Both had oil in the head valley. If Scott had any concerns he would have looked inside. I have a bore scope to use.

[@artymike4506]

When you order parts for a BOAT, does the parts company charge you extra for the injector because it is going into a MARINE engine?

[@slyguyaction]

What kind of torque are we talking about with these engines? Each?

[@Cemi_Mhikku]

Any idea if they're planning on restoring her? All that exterior wood's in pretty rough shape. If so, this is a great start on it! Edit: No pun intended, but I stand behind it anyway.

[@buenaventuralife]

I am rebuilding and recommissioning her. The engines running makes all the work go easier. Scott taught me a lot so I can handle them now. It will take a few years to get her back in a nice condition. You can follow my work on the Buena Ventura Life.

[@simonmorris3964]

Why does it seem to always happen that way. End of a big job ......eager to start it, ....and the starter gives up.

[@markvansledright7653]

Nice Job. Do you have a remote starter button. Let me know I might have an extra. No need to make sparks with the screw driver then.

[@buenaventuralife]

I plan on adding a remote start button to the engines. It is a lot of exercise running up to the fly bridge to start the engines and then back down to the engine room each time.

[@cobrasvt347]

Is one counter rotating or do they both rotate the same way and the counter clockwise is done by the gearbox?

[@buenaventuralife]

They are counter rotating.
