Good luck

Hi Mschesser, thanks for your support and comments

I have changed the oil and filtter and there was no milkiness in the oil, the oil filler cap had no signs (droplets) of water on it. 
Since changing the oil there has been no raise in oil level. 
Cheers again for your suggestions

Hi Steven,
Thanks for your valued comments and suggestions 

When the engine is running there is no white smoke or steam from the exhaust, it is how it has been since getting the boat a year ago. We have even taken samples of the exhaust outlet water.

Hi All 
Thanks to all of you who  have made valued comments and suggestions on this topic

It was suggested (somewhere) that it maybe the saltwater raw pump and I did have a very small drip from it, so two days ago I took the pump off and it is now being serviced. So I can not run the engine. I filled up the coolant reservior and to my surpise in the morning it was empty. Here are three photos 



Taken at 1334



Taken at 1341



Taken at 1642

This is the third time the reservoir has been filled. ShockedShockedThe engine can not be ran as no saltwater pump. There is no evidence of coolant anywhere to be seen even been over the side and looked at the exhaust outlet.

What I dont understand is the liquid is below what I belive is the feed pipe into the heat exchanger ConfusedConfusedConfusedConfused shown by red arrow.

Any suggestions welcome 
Desperate Ian

hi

Just a random thought Remove the reservoir from its mountings fill it up again and then lower it until it stops losing fluid - this should give you the level at which the leak is accuring =?
