Thanks for service, my grandfather always said the 2strokes hit the beach on Normandy as grey marines, powered us through wwII and built the interstate system in North America
More like 8 miles if you lived where I did growing up. My dad drove an old gmc back in the 70's we lived on a hill . My dad would travel mountain top road from work to home . I made sure I was outside.
We use Detroit’s as turbine starters offshore. Once started, they idle for about 20 seconds & then it’s balls to the wall for them for the next 5 minutes. Beautiful noise from the motor & supercharger.
Oh boy, you can't mistake the sound of a Detroit! Back when I was trucking with my dad. One of the trucks he trained me on, had a 8V92. It was a 359 model Peterbilt, flat top. With the double sleeper. About a 83-84 model, with a 15Sp. Fuller O.D. which took getting used to. Because it had the upside down horse shoe pattern from 3rd-4th. and 13th-14th. In 15th gear, you were either lugging or flying!!
We had an old Hatteras with 12v71’s in it. 3am, we’d wake the entire marina up when we’d leave the dock to go fish. Thing ran like a tank though, one of the most solid sport fishers I’ve ever been on. Now we have a Hatteras 56 with CAT C32’s. Lot quieter, but I miss the old Detroits.
My grandad had a 42' Uniflite with twin 6-71s and this video just took me back 35 years. Such a sweet symphony when the two engines were running in synch. It was one of the last heavy hull boats Uniflite built and those jimmys could get that thing up on plane in pretty quick fashion.
That sound and smell when you first fire up a sportfish at about 4 in the morning is something that imprints on your brain. It has been burned into mine for over 50 yrs because I know iam going deep soon...
Awesome. I spent the summer of ‘86 out in Montauk working for my uncle. He had a 42’ Bertram with twin 6V92TA’s. Loved hearing those things sing. Nothing like it
when I was in diesel school way back when they had an 8-V 71 on its stand and did a dry fire. pop off instantly, but me at 19 reach and grab the throttle body and yank the crank. that things roared blew fire about 5 feet and 19 people left the room as the ground shook. I was in love
One of the first bankout wagons I ran had a Detroit. I got in the cab and sat down, started the engine and the guy who owned it and who's rice we were harvesting look at me and loudly said "run it until it sounds like it's going to blow up....then give it some more!" I'll never forget that for as long as I live. That was a fun machine.
A lot of folks trash talk Detroit’s they are one of the most dependable, and easy to work on and maintain diesels ever built . If you were trained to work on one , you could work on almost anything they made.
Depends on the year. Series 60 is a fantastic motor. Loved when those buses were on my run card. Now it’s just Daimler renaming Mercedes engines. I despise the DD15.
I randomly clicked on this video for the hell of it and I noticed that it said Weymouth Ma, and I was like “ oh no shit I know where that is!” Becasue I literally live on the cape haha
If you were to shoot about a half second of ether into each intake silencer, you would save the batteries, save the starter motors, and prevent the knocking which is caused by the accumulation of liquid fuel on the tops of the pistons igniting as the engine finally starts. Of course you'll get all sorts of advice from the "experts" as to how ether will kill the engines, but used properly it doesn't. In the winter I used a quick shot to start a pair of 6-71N's in my boat ( I'm in Canada ) and in the summer it wasn't needed as the air temp went up. They were the advanced cam timing high compression engines, and they would blow a few seconds of light grey smoke on a cold start and nothing more after that. Very nice boat you have.
I have a friend with a 44ft Pacifica that had twin 8V-71s that had a top speed of 19 knots, cruise 15. Through California re-engine program (since he did commercial 6 pack chartering) he qualified for re-engine the boat with twin 500hp Cummins QSC engines. He lost about a ton of weight and his fuel consumption went down to almost half. Remarkably at 7 knots, the two engines combined only burn 2.7 gallons per hour (that's as good as a single engine trawler). He can now cruise at 20 knots and tops at 25 knots.
@@RJ1999x the new electronic engines (with common rail fuel injection) are much more efficient than older mechanical injection. My big rig Caterpillar (14.6 liter) burns about 1 gallon an hour at idle. My friends boat has 8.3 liter ISC Cummins in then. Pull up a propeller curve of that engine and you’ll see the fuel burn
My uncles boat has twin 6V92TAs and was a little slow amd smokey on startup. He's since gotten electric coolant heaters installed to keep the engines somewhat warm and it made a huge difference. Nearly instant startups and no longer smokes out the rest of the harbor on cold mornings
Was on a boat in Hatteras with twin diesels and one ran away about 9 miles offshore on the way in and caught fire and sank. That sound of those engines in sync will forever scare the living shit out of me.
