A friend of mine has a technomarine cobra 60 boat it has twin Detroit diesel fp series engines to run it one of which is overheating so looking for a Marine engineer or someone who is familiar/competent on this type of engine the boat is in the Famagusta area any recommendations would be most welcome.
First thing to check would be the Impellar. This inside the water pump on the engine, driven typically by one of the belts. This sucks the water up through the strainer (make sure that's clear of debris), and pushes it around the engine and back out through the exhaust system. Also make sure that the water intake under the boat (intake point for the strainer) is not blocked by 'creatures'.. If partially blocked the Impellar will not draw enough sea-water to cool the engine.
If the above is all good, then either the engine thermostat (which on a marine engine is not common to go wrong), or more likely the heat exchanger is blocked.
There is a product you can buy here (it's American), called Barnacle buster... I use it once a year. Look on YouTube for videos on how to use it.. Comar Marine (Larnaca or Nicosia) sell it.
