I don't understand your comments about range and sea-keeping.
We owned a 1984 48 MY....virtually identical...and after doing the loop, went from Florida to the Bahamas; Turks; Dominican Republic; Puerto Rico; BVI' s ; St.Maarten; etc., etc to Grenada....and back.
A great vessel and we still miss her. Our story with recommendations was published in two issues of Southern Boating back in 1999. She was very stable and handled blue water very well. We never had an issue with range concerns.
 
Nice looking boat. Needs the exterior wood done, but there is a manageable amount of it, not horrible.

92 DDs are not my favorite engines, but with a serious survey you could live with them. Reasonable asking price, seems to me.
 
92s with over 3000 hours.
They are not maxed out HP engines but it is time (or soon) for rebuilds.

That is also a very old gen-set. Running or not, zero value there.

Why? How can you say that based only on hours. I've got 5000hrs on my 6v92's and they start and run great. It all depends on how they were run and how they were maintained.
 
I have 3600 hours on my 8v92's twisted to the max HP and they made the trip from Florida to Wisconsin with the Bird without a hickup. Didn't even need to wash the transom when we arrived.
 
I see my 3000 hour comment stepped on some toes.
Sorry about that kids.
Your engines are doing you very well.

Having been around Detroits most of my life, I have resolved the mortality rate for a 92 is 3000-3500 hours (including fuel consumed and proper maintenance)..
There will always be different cases of shorter and longer lives.
Keep up your good maintenance, luv and luck.

If the O P is shopping for a 92 series propelled boat and does not understand the luck or pucker factor behind a used boat purchase with them in it; I hope we can help, even with different opinions on build / rebuild schedules.

I have 3,200 hrs on my 1292's. They can sit for a month and i swear they start before my finger touches the button. They will give one puff of smoke as they fire, if its below 50 they will smoke for 10-15 seconds. They leak oil but I've never had to add between oil changes. Usually about halfway between add/full at 100hrs. I'm not sure why everyone thinks motors need a rebuild just because of hours. I've also never understood why everyone pushes an engine survey. I'm on my tenth boat and only had an engine survey on one of them, and I was pissed off that i wasted my money on that one. the motors will tell you everything you need to know with a cold start and sea trial.
 
No ruffled feathers here. I hope you are wrong in my case but if one or the other goes that means someone will get a nice 60' MY (if I do say so myself) with rebuilt motors some day.

Curious, what are the signs the old girls are going to give me trouble? These are my first diesels.
 
In a sportfish application Capt Ralphie is spot on. It's been my experience that the MY kids get a lot more time out of them having been running them at lower RPM's.
 
The PO put 29X32s on because he didn't need or want the speed so I'll guess it was run at hull speed a lot. We run her 12-1300's then push her up to WOT to get her up then drop it down to 19-2100 for a bit to here the turbos scream before we enter the harbor.

The biggest thing for overall motor condition is cold start, that tells you if they still have good compression. If they start quickly and the smoke clears within 30 seconds they are still in good shape. You also need to keep an eye on the horizon behind you. If you see a haze you need to look into it, could be injectors, the rack may need to be run, or it could be over propped. But if your leaving a haze behind you a lot of times it means you're working the motors to hard, which will lead to a rebuild shortly. Mine had developed a haze over the last year and it ended up being a bunch of worn rockers on the injectors.

Even once they get tired they will still run for a while. I had a boat with 671's that started hard and would clear all the bugs out of the marina when it did start. once they warmed up they ran great. I sold it like that and the new owner put another 500-600 hours on it before he had them rebuilt.
 
Fact of the matter is that 92's got a bad reputation when they first came out and almost bankrupt GM engine. But the "silver series" corrected that bad sleeve o-ring issue. That didn't matter to some people and that bad reputation continued. We owned a bunch of these in trucks in the early 80's.

So, we have 92 haters out there who will never acknowledge that they are indeed just as good as the other Detroits.

Anyone who tells you anything about the longevity of an engine only based on hours is speculating at best. Get an engine survey if you want to know the condition of the engine. It may be close to rebuild or it may not. Only the survey will tell you this. Generalizations are worthless.
 
My surveyor said run clean gas and change the oil regularly. That’s it so I guess I’m good. I realize the importance of my DD’s and the cost if I don’t. I love saying that.:D

But please don't run gas :)
 
Gas won't run them. They will sputter and die quickly.

A colloquialism. I used to step on the airplane and ask FO/IRO whether we were getting "gas" yet. No one blinked.

Dave and I know each other. It was simply a joke. And these are boats, not aircraft.

Didn't know the relationship, of course. And I say the same thing on my boat. :p
 
I apologize if I upset anyone.
