Oil Analysis

We just sold a boat. I have included the oil analysis. We had to knock off a 1,000 to close the sale.

How lucky did we get? I'm not a diesel guy but the analysis looks like trouble to me.

What do you think? This is an 80's boat with original Univeral.

Interpretation Text:MODERATE AMOUNT OF IRON AND DEBRIS VISIBLE UNDER MICROSCOPE. SOME DEBRIS APPEARS COPPER/ BRONZE. IRON(FE) APPEARS ELEVATED. RESULTS MAY BE REFLECTIVE OF THE BREAK-IN PERIOD. MORE SAMPLES ARE NEEDED TO ESTABLISH A TREND. ALL OTHER LEVELS APPEAR ACCEPTABLE FOR UNKNOWN HOURS ON OIL. PLEASE INCLUDE HOURS WITH FUTURE SAMPLES. SUGGEST CHANGE OIL AND FILTER(S) AND RESAMPLE IN 50 HOURS TO MONITOR.

Interpretation Text:ELEVATED POTASSIUM(K) MAY INDICATE A MINOR COOLANT LEAK. POSITIVE REACTION TO TEST FOR GLYCOL. CHECK FOR CRACKED CYLINDER HEAD AND/OR LEAKING GASKET OR SEAL. ALL OTHER LEVELS APPEAR ACCEPTABLE FOR UNKNOWN HOURS ON OIL. PLEASE INCLUDE HOURS WITH FUTURE SAMPLES. STOP UNIT IMMEDIATELY IN ORDER TO CORRECT PROBLEM(S).

If you have an engineering problem solve it.

Re: Oil Analysis

I think except for the potassium level, which is a real measurement if it had a number, the rest is just word ******** (the feral matter that comes out of the rear of a male cow).

But for a buyer who had enough question in their mind to do the analysis I think you got off cheap.

Don't blow air up my rear, be useful and blow it at the sails!

Re: Oil Analysis

"POSITIVE REACTION TO TEST FOR GLYCOL." Pretty lucky, IMO. But honestly, had our engine not had only 30 hours on it I would have preferred to swap it out for a Gardener right from the start. Not that I'm not taking good care of this one. But one day......

Re: Oil Analysis

Who did you send the sample to for analysis? I use Blackstone Labs. I can call on any sample and speak to a tech who will break down the numbers into real world information. For example, lower than expected flash point indicates fuel in the oil however, it does not necessarily mean you have a problem. Extended idle time, cold sample etc., can cause anomalies in the sample.

Having a history on the samples is always good, without a base line it is difficult to develop a sense of what the engine is really doing. When we do aircraft samples we have a significant advantage as we have engineering data on the engines and can predict very accurately what the sample "should" look like.

Re: Oil Analysis

I too use Blackstone for my airplane and rice rocket and will on the next boat. Great guys, great service, good reporting and trend monitoring.
Thinking it's just a scam to sell more sampling is plain foolish. Excellent engine monitoring at the microscopic/chemical level. We also check screens and filters regularly for larger evidence of problems. Guessing on a boat, if like my last one, the sampling would be fairly infrequent due to lack of hours. I don't think I put more than one oil changes worth of hours on mine in the 8 years I owned it. Won't let the next one go so long as time affects oil too. Maybe more critical on aircraft but just the same......

Re: Oil Analysis

If it was the M25 on the O'day, I suspect that someone installed a new raw water pump (iron and copper/bronze), and the alternator bracket was recently replaced (resulting in coolant contamination of the oil from the exhaust manifold bolts).

It sounds like you got ~$30K for a plain-vanilla O'day 35 (no modern electronics, no traveler, no dodger no bimini) which seems about right. In what condition were winches and the sails? Was this the shoal-draft version?

Re: Oil Analysis

Winches and sails were fine. If I remember the draft was about 5' maybe a couple inches over.

The guy that bought it came from FL and shipped it back home.

I would have thought he could have found a boat closer but who knows.

You don't think the glycol was a problem?
