"Hey guys,
I just replaced the complete water pump,in my Merc 160 outdrive.Housing, gaskets, and impeller. I also replaced my exhaust riser, and checked the saltwater tubes in my heat exchanger for buildup. the tubes were clear. Replaced the thermostat with a 160 degree unit and replaced the freshwater antifreeze. My problem is that the engine still overheats with a load above 2000 rpm. It cools down fast when I slow the engine down to about 1500 rpm. I seem to have a good stream of water on the input side of the heat exchanger coming fro the outdrive, and a good flow of water coming out of the manifold. Any suggestions ????? thankyou in advance for your reply !!!!! Dave"
