Detroit baby! Pound for pound these engines smashed any 4 stroke engine of the same era. The technology exists now to build advanced two stroke engines with the next gen being opposed piston designs. What a waste to replace these magnificent, gloriously sounding engines!
3900 hours is equivalent to 136,500 "Miles", at least when it applies to construction equipment and generators. Unless the engines were run out of oil, or overheated, they have a TON of life left in them! 27 years in the trucking industry and NEVER had a customer come in for the shop "just for an overhaul". Truckers will run their equipment until it won't move anymore. As long as the A/C works.
End of an era as those old heavy oil guzzling 2 strokes are replaced with modern 4 stroke motors that burn cleaner, take up less precious room,. and are thousands of pounds lighter. Typical 20 knot spt. fish will pick up 5-7 knots after repower.
@@rski1036 I doubt I will get much with a repower. The heavy weight down low actually helps with ride quality..fuel mileage isn't terrible either. I get twice the mileage of my friend with a 76fter and .modern 4 strokes
Why on earth with 3,000 total run hours have they been rebuilt at all? My last engine had 15k hours on it when it rusted out. I have many diesels with 7 to as much as 18k hours. The guy must have ran it on the pin all the time.
The 8V92 produces 312 hp (233 kW) of continuous power at 1,800 rpm. Intermittent power is 362 hp (269 kW) at 2,100 rpm. Maximum power, on the other hand, is 388 hp (289 kW) at 2,300 rpm. This engine has a displacement of 738 cubic inches (12.1 liters). A turbocharged version was developed later on.
My grandfathers 1983 46’ Viking has the 8v92s with twin turbo and superchargers. When you say the turbocharged engines developed later on, would that mean those engines were outfitted with the turbo kit after the original sale? I only ask because last year we had one of the manifolds replaced as it had rusted straight through and just today we had suffered the same problem on the other engine (outboard side, same as last year’s replacement) and I was wondering if that could be related.
@@ryanehlis426 3500 for a 8V92 is not a good idea as they have week main bearings to start with. just ramp up the timing and the flue curve a bit and you can push the pony's pretty safely. being the sea version it should have the big cam to start with.
Harts Fire well i talking more about the 60 series. My work truck has a mild tune and does everything i need inside 2400 rpm. But in truck pull applications they go 3500rpm.
@@ryanehlis426 i do like 60 series my self. but i run the old 1996 navistar 7.3L yes it is a power stroke compound turbo turned down to around 400hp at the wheels my self in my personal truck
@@BillChurchFl this is no lie. we have a 86 POST with two 671TI’s. wouldn’t trade this battle wagon for anything other than a bertram of similar year but the post has much more modern styling.

No way I would swap out those perfectly good engines

Very impressive and descriptive video of your boat plus your understanding about engines is brilliant
Terrible audio, but other than that thumbs up
Wow that's pretty darn fast for such a big boat!
Agreed. What a beauty!!
I enjoyed this ride along and the description. We want one day to set up to complete the great loop. Thanks!!
4000 hours and no smoke? So many hours left to give.
Thank you for the vid 😎👍 very nice indeed 👌👍👍👍👍👍
I thought I recognized that area. Its where they filmed Catch-22
San Carlos...Sonora Mex...yep...Catch 22 beach is 2 miles away

Marine duty
Each one is probably putting out 750hp

With a lot of time left to those engines, why were they scheduled to be pulled out? Those Detroit diesels are hard to kill.
Can you post this with refitted audio
That’s San Carlos,Sonora right ?? Nice video
Lost all my money in a boating accident. I accidently bought the boat
B O A T: break out another thousand
Looking at a 50 hat with 892’s
Shocked to see that top speed!
What was her speed at cruise?
sea trial fancy ass name for test run/underway/ test drive for normal people
Woah audio
Normally we go by hours of operation.
Yep swap them out for mack e7's all mechanical
2250 rpm some one has them turned down it is vary safe to spin a 8v92 up to 2800 rpm.
Yes but 2100 to 2300 is more factory Standard rpm for Detroit diesel for performance aplications Some rune them to 3500 rpm

736 cid 735 hp ❤️ Detroit
Those are great engines but not a nice place to work in we had to rebuild a 371 2 871s and a northern lights lugger.
Was this filmed on a potato?
Who cares about the age of those motors. What are the hours?
The audio in this video is terrible
wonderfull detroit´s
Your mic is too loud for this video lol
What is the cost to rebuild 6V-92's. Engine ?
I paid 9k/side on my 1974 hatteras 42 convertible
Lots. Twenty? Probably more now. Been retired quite a while
Glenn Thompson are these still available?
Recorded with a potato
The worst microphone in the history of TH-cam
jd , dont buy it it
jd, ?8v92, 900 hp if cooled write
What a waste to spend so much money on an old boat. You could use that cash to buy a new one.
because they don't make them like they used to...

The only thing worth saving on that heap was the DD's.
Nevermind the smoke. I would worry more about working for a brown fellow! Did you get kidnapped my friend?
