Sorry Long post. but if you have cooling problems this could help.
OK , so now i know , I should flush out the raw water cooling part of the system with something that will remove the scale at least once every year or so. My BMC was getting warm under load all season. Nothing in the filter , water pump and impeller were both OK. I stripped the Heat exchanger , a little scale but nowhere near blocked so i stripped the exhaust manifold exchanger. Same here , removed thermostat and rebuilt everything. Ran it up , better so took it for a run to load the engine, got hot!
After reading other threads and becomming desperate as rumers of nasty things like head gasgit replacement and engine & gearbox removals were getting a bit real. I drove 100 miles round trip and bought 2ltrs of Rydlyme at £9 each. Last w/e i sat on the boat and connected up a 12v circulation pump and for 4 hours on Saturday and another 3 hours Sunday ran the stuff through my cooling system . I ran out of time for a motor up river untill today.( but did catch a few small bass , returned as too small to eat) Today i ran her up tide against the wind wide open and she never got hotter then the thermostat cut in of 74deg.
So if you are having problems keeping your cool give Rydlyme a go could save you a lot of time and expence.
I have no connection with this company .
Hope it helps.
