Extremely impressive and educational, thanks so much for filming your work!

If it helps someone else then our aim has been achieved. Thanks for commenting 😄

On my D2-40 I had steam above 1850 revs. I added a salt water intake by using a T on the sink and a Y to the salt water pump. It solved the problem. I also added a filter to prevent barnacle to get into the impeller. This also provides an advantage whenever a plastic bag might block water intake on the sail drive.

This is something we are considering doing. We think having a separate intake for cooling the engine would be better than relying on water coming through the sail drive, which has a very small opening and is easily blocked. Thanks for the idea.

Sea water go's through the heat exchange tubes thanks 😊

The sentence has a great start, but the end appears to be missing. We hope you are enjoying our videos and have subscribed to support us. Please finish your comment and we will respond.

@@sailingseagullsouth I think the comment refers to something you say at 7:14- the heat exchanger has salt water in the tubes and fresh outside the tubes. Thanks for such an in-depth video. We have steam coming from our old TMD40. Sigh.

@@Karma-fp7ho I hope something we did helps you solve your problems. This one took us ages to figure out.

You changed a number of parts on your engine and the problem has been solved but if you had to pick one item that solved the problem which would it be?

[@sailingseagullsouth]

This is tricky, but the fuel injectors is probably the one.

I’ve just changed the exhaust elbow on my Thornycroft 230 d engine when I fitted the new one the engine started and stopped within seconds and will not stay running each time I try Question 🙋 Do you have to bleed the water system or something when you change exhaust elbow thanks 🙏

[@sailingseagullsouth]

@@sailingmsmalachite1503 We do not know about your engine specifically, but we primed our raw water filter by filling it up with tap water to create suction. Once water is coming out the back consistently it shows its working. Not sure why changing the elbow has caused the engine to not work. Sorry.

How do you explain the combustion gas in the coolant? Seems like the head gasket must have had some seepage. Did you repeat this test after re-assembly?

[@sailingseagullsouth]

@@1768ify We did change all the gaskets when we had the block off the engine. So it may have been a gasket issue.

[@dpalt007]

Thank you very much... we have the same Problem with our 2040 think we are doing the fuel injectors.

[@sailingseagullsouth]

We hope it helps. It's so frustrating when you don't know what to try to fix the problems. Let us know if it works. 😀

[@Steve-ul8qb]

Hey mate, did it work? Currently having the same issue…

[@sailingseagullsouth]

It's been great for the last few seasons. We wish you the best with solving your problem.

[@Steve-ul8qb]

@@sailingseagullsouth thank you. It’s driving me mad 😂
