6-71 Jimmy start up

[@MarcvanExel]

I used to be in the scouting when I was young. We had an old barge (spits) of a 126 feet long powered by a 6-71. The barge was built in Belgium in 1908 and this engine was later fitted. When she was still earning her keep she could load 350 metric tons (about 385 short tons). She was a loud and slow barge but I always loved the engine music.

love that sound of a detroit diesel 2 stroke

[@tbamagic]

I had a 50' trawler yacht in Sausalito with a 6-71N natural. Ran it for 15 years with nary a burp. Terrific engine.

Back in the day, when these were in trucks, I was told that the first thing you do in the morning is slam your finger in the door. Why? Because they run best when you drive it like you're mad at it!

Truth

[@michaelbenoit248]

My Little Yanmar diesel on my lawn mower is happy at full ass whose open/governor/ 3600rpm. My 7.3 idi on the other hand likes to hang out at 1500-2000. She’ll do 3300, but I rarely take her there when I need to pass a moron. Most newer diesels need to be run hard. But yeah, Detroit’s are the the one Diesel engine that need to be driven hard, they sound like they’re going fast, but it’s a 2stroke so it’ll sound like it’s doing 5600rpm when it’s only doing 3300rpm.

[@zopEnglandzip]

@@michaelbenoit248 agree the newer diesels have to be run hard to make power but they ain't built so tough, ag tractor industry is a joke right now.

[@ericmorin1860]

Nice clip, and nice engine room!. I am in my first season with 2 x 6-71TI . Keeping up with the oil leaks has been a challenge, but quickly learned to appreciate the engines and their history.

[@JohnAdams-to5ch]

How have you made out keeping up with the leaks from the "green leaker"? Looking at a boat with twin 6-71 TIBs. Thanks, Eric.

[@joefwarren]

Worked on supply boats in 90s. Couldn't sleep when I got home after 2 weeks of listening to those things

[@theq4602]

Wow didn't think a 6-71 would power a boat that big... Now I see why the marine industry loves those engines.

[@1320fastback]

They can run big injectors using the entire ocean for cooling that a truck or RV could never keep cool.

[@Dave5843-d9m]

These engines will happily make double the power of a similar size fourstroke. No surprise really - each cylinder makes power on every Revolution.

[@1958johndeere620]

@@Dave5843-d9m Not so much. A non turbo 671 usually turn 236 horsepower. A non turbo 8v71 is 318.

[@jamesgeorge6551]

@@1958johndeere620 I know of several 6-71 TIB engines with N90's pushing 450 HP.

[@1958johndeere620]

@@jamesgeorge6551 I said non turbo models. Every diesel engine, being 2 or 4 stroke can be fueled to run many horsepower ratings. My point was they don't make double the power of similar size 4 stroke. Right now you can buy a similar size marine cummins engine with 550 hp. Yes, the detroits ran the world for decades, but they are not the best of the best when it comes to power.

[@russvoight1167]

When a Detroit quits leaking oil, that's when you worry. By then it's out of oil!

[@steveswallows8525]

That sounds like an SR71 Blackbird. They say if it's not leaking fuel it's empty.

[@ericcommarato7727]

Interesting how the exhaust and cooling water are separated unlike the combination marine water jacket exhaust risers that inevitably rust out.

[@admdhc5583]

two stroke 1000 rpm sounds like 2000 rpm at 4 stroke LOL

[@chickey333]

Yes they do. They're real screamers in double ended earth scrapers.

[@ronmeidlinger249]

Because there are the same number off power strokes at 1000rpm for a 2 stroke as there are for a 4 stroke at 2000 rpm

[@davidmg1925]

Nice sounding 6.

[@grngs1]

Cold oil pressure is abysmal, only 20 psi cold? Whats it at hot, 0?

[@Trucker1957]

Gorgeous boat!

[@enginemaster01]

The old style furuno radar brings back memories

[@spartonboat1]

I find the oil pressure interesting. If cold, it should easily run up to 50 #'s. If warmed up, then when run up to 1,100rpm, then it should raise toward 60#'s, then drop back to 50 #'s. They have a pressure relief valve that releases above 50 #'s. Otherwise pretty engines.

[@johnb4183]

oldcarboater he was talking about 140 / 150 psi oil pressure =??

[@spartonboat1]

Most internal combustion engines run around 50#'s (pounds of oil pressure). The Oil Pressure gauge is on the lower right part of the gage panel and the needle is sitting just under 20#'s. The low reading could be due to the sending, although sometimes the oil is brought directly to the gauge, via a metal pipe. So again, on a nominal (what it should be) basis, it is low for a cold engine. 20-25#'s is normal at idle, when fully warmed up.

[@tomjones-Hawaii]

I prefer a 40-50, but if the owner thinks its alright, oh well. Its still a great engine..

[@1958johndeere620]

You only need 10 psi per thousand rpm's. 20 psi at 1500 is plenty.

[@RJ1999x]

You guys are talking about normal engines, Detroit's run very lo oil pressure 5# at an idle isn't unheard of!

Best to avoid revving diesels without load. Just put it in gear and wind on the fuel.

[@robertborchert932]

Detroits are an easy target. Let's get real. Who properly maintains them? They run strong despite neglect. Don't take care of them for years? Hell, that Detroit is still running isn't it?

[@geraldbostock9858]

Detroit v. everyone.

[@prevost8686]

Their reliability was the reason many of them got the reputation of leaking so badly. Few of them ever got pulled down for regular maintenance and repairs because they would just keep on running.

[@robertborchert932]

@@prevost8686 you're right! Years in the fire service kindled my love of the 8v92, the smoothness, the power, and the sound! In the engine bay of my good friend's Country Coach rests a lovely example. Only oil leak we've run into was the accessory plate behind the air compressor, just loose bolts. New gasket and a tidying up was all she needed. It was fun pulling the bed cabinetry, Country Coach cabinets are a joy to behold, built very well with the idea of allowing access to the Prevost's access door. The engine cradle is also brilliant, doing an inframe bearing job looks simple, But building a proper dolly to pull everything when needed will be nice. We replaced the exhaust system a few months ago, the original muffler was showing its age. The new system surprised us both! The sound is a wee bit louder, but it purrs exactly like a fire apparatus. A bonus, the pyrometers show lower temperatures, and the blowby has decreased. I tease Doug, I really want to redo that silver paint in all its glory. Mind you, there's no oil on the exterior of this Detroit!
