I got an AA report & showed the vendor, He didn't want to loose the sale so we agreed on a revised price, bit like the oil sample, if your not going to use it whats the point.

He has a problem with me as I didn't think buying cheapo Chinese heaters (that if fail could kill) was a good idea. Everyone to their own, I just hope to god one of them doesn't cause anyone harm. Testing in a garage for a couple of weeks is not going to find a problem years down the line, mattresses (good ones) get more testing than that.
I don't suppose he bothers with surveys & tests.

Is this a boat you are considering buying or one that you have owned for a while? Here are a few considerations
How long is it since the oil was changed? An oil sample is only worth doing if the engines have completed 30-40hrs minimum otherwise it is not representative of the condition of the engine
How long had the engines been idle before an oil sample was taken? If the engines have been idle for a long time then some of the contaminants might have sunk to the bottom of the sump and therefore again an oil sample may not be representative of the condition of the engines
Where was the sample taken from? If a tube was just pushed down the dipstick pipe and oil sucked up, it might have been pushed all the way to the bottom of the sump and picked up a lot of contaminants which again could make the sample unrepresentative. If the technician who sampled the oil cannot tell you at what oil level he took the sample then he didnt know what he was doing
Oil sampling can be very helpful in assessing the condition of an engine. I do it for every new (to me) boat I buy and then keep doing it every year to identify any trends. It is trends that you should be looking for rather than isolated results but if a single sample shows a high contaminant then it is worthy of further investigation. In your case it might be worth doing another sample to confirm the results of the first. It also might be worth speaking direct to the engine manufacturer to ask whether the iron content level is actually excessive for the type, age and hours of the engines.

I see it as a comment about how another person behaved not a personal insult as you seem to see it...… Why do you feel you have the right to tell others what they can and cannot post...…. What is your comment about the Boat issue.... Perhaps it is time for you to look in the mirror

Perhaps you should therefore understand the value of your work & apologise for your earlier comment.

I understand my Industry and feel no need to apologise to you. Look back at some of your comments and ask yourself if you need to apologise. The issue I have is that you sit there from I think (I will stand to be corrected) a position of wealth decrying those with smaller means for trying what you deem to be cheapo things. This is despite me proving why the so called non cheapo units were expensive. Namely the cartel. Ebay and the Chinese are here perhaps you need to grasp that fact

I guess I need not reply to that, readers will draw their own conclusions.

Going back to the op's query, without knowing the number of hours since the last oil change, the results aren't terribly helpful. It is however of some comfort that the results are similar for both the engines.

Back to helping Russ , I’m sure he won’t have the time to be reading personal crap.
Did you take the first sample through the dipstick and bottle it , I hope not as that’s just a false sample.
Did you ask the owner how many hours the engines have run since the last oil change .

Thank you Paul.
Yes sample was via dipstick after an hours trial at speed. Quite possible as mentioned that I may have bottomed out on the sump crud oil.
I have sent an email asking for the last service date as I cant remember from my visit.

the oil sample can be useful in other ways.
A Turbo 36 was recently rejected after an oil check on both engines engines,Cummins 300Hp.
When results returned, from Cummins dealer it showed a highish amount of whatever goes into Anti Freeze diluted in oil sample.
When anti freeze percentage was checked in suspect engine, found to be 99% pure water.
It was thought that as engine lost its coolant via either head gasket or heat exchanger, owner had just kept topping up with pure water.
A hefty bill would have been on its way for any new owner.

Sensible advice from Paul as usual. It is really difficult to make concrete conclusions from 1 sample, as there are lots of unknowns, not least the age of the oil, and the thoroughness of scavenging the old oil when doing the change.

How would you explain what was done
