My starboard engine at higher RMP is overheating,and if I bring the RPMs down around 2200 the temp will come back down. I have replaced the sea water pump,the thermostat seams to be fine and my mechanic says my water flows are fine. He says now the next step would be to remove the heat exchanger soak it and flush it out with meratic acid because the boat has been in salt water in its previous life. Has anyone heard of this methode ????? Or what else could be the problem???:smt017
