Hi, I'm posting this on behalf of my dad, unfortunately he's not of the technical age..
He has a Perkins Sabre M225TI, The engine is 16 years old and on 2200 hours, very well maintained and never taken above 2200 RPM.
Two years ago the engine developed a temperature issue where after long periods of steaming it would rise from 82-88 degrees C at 2200 RPM.
Firstly we cleaned the fresh water cooler and gearbox oil cooler both being clean to start with, a new thermostat was also fitted and tested in various jugs of water with water temperature sender.
This did not cure the issue, since then we have -
The engine has an electrically operated advance/retard unit, we're unsure if this is causing a fueling issue leading to overheating, the engine runs fine apart from temperature and is not smoking.
We've already had an engineer and a marine engineer look at this issue and this is starting to get expensive! Please help.
I'll try to reply on behalf of my Dad as often as I can.
Thanks!

This did not cure the issue, since then we have -
- Fitted new cam, backplate, wearplate and impeller to Jabsco saltwater pump
- Flushed engine with flushing fluid twice
- New air filter
- New genuine Perkins turbo and wastegate (old wastegate was apparently seized)
- Cleaned intercooler
- Checked seawater output from exhaust (found to be over 27 gallons per minute)
- All pipework is of recommended sizes
- Run with engine box open to ensure engine has sufficient air intake
- Engine oil,gearbox oil, fuel and oil filters changed yearly with recommended Shell Rimula 15-40 and genuine parts
- Tappet clearances have been checked
- Hull has been cleaned and re antifouled
- no oil in water at all, sniffer test has also been done and found no fumes in coolant
