Happy Holidays to you all!
I'm a bit of a novice so please forgive any wrong terminology or wrong descriptions.
My Ford Lehman 80 is overheating. It usually runs at full throttle (and a roaring 6 knots) and the engine temp hovers around 180/190 degrees celsius.
Recently it's been getting up to 210/220 degrees and so hot there's a fair bit of white smoke out the exhaust and the radiator cap even blew off.
I've checked and there's plenty of oil, plenty of coolant. There was a lot of growth on outside underside of boat so I had the divers around. They said the sea water intake had some growth now removed. Here's a video of the seawater cooling system in action at about 75% throttle.
Is that functioning correctly? I noticed that when at a decent throttle the water level in there is low, it's like it's sucking out all the water waiting for the new stuff to flow in, not constantly filled. Not sure if that's a problem..
Separate to that (or perhaps another cause/problme) I believe I now hear a 'whooshing' type noise in the engine which wasn't there before. I can't diagnose where it is (or if it's even in my imagination...)... but if the sea water cooling system is functional perhaps something else is wrong..
Any ideas greatly appreciated!
