Starting Twin Detroit Diesel 671-TI upgraded to 485HP From Cold Start

[@MrWhat-ef1xr]

The really great thing about owning any yacht with Detroit Diesels is YOU CAN GET PARTS ANYWHERE IN THE WORLD ! A real plus when a boat breaks and it will.

[@tomdavis1694]

Just don't ask for a service call as mechanics with DD 2 Stroke experience are as scarce as hens teeth. Been waiting 7 weeks for Stewart & Stevenson to come out for a call.

[@crphilipp]

No one will work on them!

[@rsea910]

I could just smell that sweet diesel exhaust

[@DavesRange]

One of the best smells

[@rsea910]

@@DavesRange heck yea, that combined with the smell of the sea. brings back child hood memories

[@timheersma4708]

I love the smell of diesel in the morning, it smells like...power 😁

[@Vulcan650Vampire]

Those engines sound great and your voice sounds just like Tom Green lol. Happy cruisin’

The epitome of engines. Detroit.

[@andrewking4885]

Dangar Marine in Australia did a dyno test on a 6-71TI about 485 hp@2500RPM They reckon at those revs they start to develop a problem called ''fretting of the liners'' lack of heat transfer into the block one mechanic said.

[@stevenjones618]

Ahhh good old greyhound buses...

[@railnut8453]

Yeah the starboard engine had quite a lope when it started. And so did the port but not as bad as the SB. The injectors need to be balanced and some fine tuning in the governor is needed I think!!!

[@cliffpalermo]

Thought the same

[@mustangcircut]

Whose brilliant idea was to install the cable master bin right in the center of the engine room?? Must make for some real great maneuvering trying to access.

John Oates on the barge next dock over?

Screaming jimmies!

[@ZoneTelevision]

What kind of FUEL ⛽️ ECON & PERFORMANCE numbers ? Thanks.

[@timbo389]

Time to adjust the governors on both 671s. And do a lot of other maintenance and those Jimmys will purr like they should.

[@travcon8]

Yall in florida, how cold could it be?

[@jacobpoucher]

DONT LET TYLER CROSBY TOUCH IT!

[@shaungilmartin1505]

just about afford to do a quick run up....wonder how many are parked up due to fuel costs?

[@455todrive]

Very nice!

[@Rev1Kev]

Time to get the Bus Grease Monkey over to tune up those Detroit’s

[@Romans--bo7br]

Some folks are deceived rather easily... ; )

[@Barchenhund]

Starboard side engine needs its buffer screw adjusted

[@darylhall3661]

Thanks. Video is a few years old. boat sold long ago.

[@joeblow4566]

Two cycle Detroit diesels

[@jesusisreal3209]

Is it sold?

[@flyin4free]

Those things need some attention! That starboard engine sounds like shit.

[@bassmek21]

I was thinking the same thing they sound very knocky

[@Roadglide911]

Obviously neither of you know anything about a diesel

[@xanaphyst]

They are running just fine. Starboard is probably just fine but if not an 1/8 turn on the buffer screw will clear that right up. All high HP detroits knock like that. It’s common to all of them.

[@michaelkeenan9526]

@@Roadglide911 I have two. Neither sound like that. One is newly rebuild and the other is tired. Still don't sound like this. You're ignorant to detroits.

[@michaelkeenan9526]

@@xanaphyst incorrect sir. Mine are 450hp and they do not sound like this at all. These either need rebuilt or some attention by a detroit wizard, which neither of the guys are...unless they know and are lying.

[@TheBeingReal]

If you slip near this boat, the diesel exhaust stench is horrible.

[@blewyd]

this is common with boats and these big old diesel engines. Everyone is used to it unless you are at a very expensive marina in the center of Miami where every yacht is brand new and over $3 million.

[@TheBeingReal]

@@blewyd I slipped behind a guy who’s nice boat was a diesel fume cloud. You do not get used to it. 😆

[@blewyd]

@@TheBeingReal i was saying that that's common for every boat that runs on diesel. Shouldn't be a crazy diesel cloud if it is running right, but it is common for a good amount of white smoke during cold starts.

[@mgp870]

@@TheBeingReal it's better than listening to drunk people or screaming children! Good day.

[@TheBeingReal]

@@mgp870 Been there too. 😂

[@SandyMoraFeliz]

Eso es boca chica RD

[@Tchristman100]

You always show the exhaust on a cold start to prove the condition of the engine-too bad.

[@ralphstacey2020]

time for infram

[@Syntax73]

lol inframe in a post sportfish?

[@darrenwebb5334]

671 isn't 485hp or whatever bs you claim. Maybe the two might make that together. 😊

[@xanaphyst]

Detroit made them all the way to 500hp with a double bypass system. It’s you that is talking BS.

[@darylhall3661]

As many diesels horsepower range varies with Turbocharging, and after cooling options to increase Horsepower. 671 Detroits were made so do 190 HP AND UP TO…. 485 HP… these engines are 485 HP… maybe you should try Google???
