That's one gem of a lady you have there. Hang onto her! If I gave mine a filter wrench for a birthday present I'm certain I would get out of bed the next morning with an unmistakable gait. She will have found someplace to put it besides the tool box.

Re: Engine Hours: How many are too many?

They are not much different than humans: if all they get is junk food, never exercise, breath dirty air, don't floss, don't get regular check-ups, are over weight, smoke 2 packs/day, drink too much booze and ignore any signs of ill health...

you get the idea.

Re: Engine Hours: How many are too many?

Hi,

Why Yanmars twice as long-lived as Volvos? Any source / article / web info on this phenomenon?

What constitutes too many hours?

What is the average life expectancy of a marine diesel engine?

To many questions? Can't help myself, still learning, and apparently "my husband says" the running on of the fingers.....ya right....lol

Velma
If the engine has had regular oil changes, maintenance, and clean fuel................. it's not even close to 1/2 life yet. 10k+ hours in not uncommon. The biggest problem I have seen with Yanmar owners is that they run the engines way too cool, or they go to the other extreme of brining the salt water side.

Re: Engine Hours: How Many Are Too Many?

There are a couple of checks, which will give you a pretty good picture of the health of your engine.
#1 A compression bleed down check. It's like a compression check, only each cylinder is pressurized & the time measured for how long it takes for the pressure to get down to X. Tells you the health of your piston rings, & valve train.
#2 A lube oil, & transmission analysis. You get a small sample & send it off to the lab, where they check to see how much of various types of metals are in the fluid. And then basically compare these numbers to an engine/transmission wear rate chart. It's an inexpensive test, & tells you a lot about the health of several different major components in your engine or transmission.

I got my Dad HOOKED on the above for his car. Gives him a Lot of peace of mind now that he's retiring... knowing he's got a solid vehicle.
So yeah, not a diesel only, specific test.
I've got the company name around here somewhere, likely in my car, but if you do a Google search, you'll come up with companies that'll do it for you. You just mail in a small sample, like 3oz or so.

Companies which run a lot of industrial equipment & engines do the fluid analysis a lot. Especially as it can catch problems early, like say a bearing starting to go bad, or traces of fuel or coolant in the lubricating oil.
Then, knock on wood, if it's a bolt on component, it can be swapped before the whole engine has a catastrophic failure.

Or if you're shopping for something with an engine, & have 2-3 days to play with (literally), you can send out a sample on the vehicle in question. And with test results in hand, bargain from there. Yeah, the tests are quick, it's the mailing that's the long part.

Re: Engine Hours: How Many Are Too Many?

People base their decisions to repower more on the number of dollars on the repair estimate than the number of hours on the meter.

Re: Engine Hours: How Many Are Too Many?

The answer to the question is another question. Are you the buyer or the seller?
