I have a 200hp Mercury outboard 1996 with 75 hours on it,It was in storage for some time. I used it three or four times and noticed the temp going up at a sustained rpm between 1800 and 2000rpm and if continued to run at this rpm it overheated. I had a new water pump and poppet installed. Since then I used it and it seems to have the same problem. It runs normal temp at idle and WOT. My question will concern the poppet valve, someone told me to cut one coil off of the poppet spring to lessen the water pressure that the valve will open and that this a dealer fix. Has anyone had a problem like this or has had this repair done?
