I am seriously thinking of purchasing a Mobo with twin 4 stroke outboards . Before commiting is it possible to have the engines oil analysed?

Yes, but what are you checking it for?

As part of my engine service Berthon send samples to a lab called Robertson Labs (I think). I had some results a few days ago actually, but the lab reports are on the boat and I'm not so I wouldn't swear to the name. I would have thought it pretty important to get an oil analysis before you spend a few £k on engines which might be shot.

I've heard these people are geared up for exactly what you're looking for. I'd be interested in hearing the outcome if you do decide to go ahead.

That was the sort of report I was thinking of. In fact it may have been the same company. I particularly like the normal/caution/serious categorisation which lent some meaning to the figures for a non-chemist like me

Thank you for the positive replies . I will let you know the outcome.

There is a strage misconception regarding value of snapshot oil samples.
On high utilisation engines oil regular sampling is a valuble tool. Often the outcome of a 'one shot wonder' can be inconclusive. Raises loads of questions and few answers. Outcome boat sales fall through.

Add to that , a good friend of mine and excellent mechanic swears by using a litre of road diesel in the engine oil before an oil change, its the best engine oil flush available.
Apparently the detergents used designed for a cleaner diesel emissions are also perfect for flushing engine deposits away, once the oil/diesel is drained the new oil will stay golden fresh looking for another 30 hours.
But I would expect an oil sample to show a trace of diesel contamination in his well maintained engines .
