    Over heating problem. need help

    ya I know its a tough one. water pressure is stable at 3000 RPM at about 12 psi but the temp builds to close to 210. Water pressure drops at higher RPMs but then the temp falls back to <180 and at some RPMs as low as 150.

    Over heating problem. need help

    one thing I have not mentioned. I have a water pressure gauge and it shows a constant 12 psi at 3000 rpm but at 4000 rpm the pressure varies wildly from as little as 5 psi to about 10 psi but it runs at about 145 degrees at 4000 rpm.

    Over heating problem. need help

    I replaced the poppet valve and all its various parts. I have not had time yet to test it but the old poppet valve looked practically pristine. I dont think that is the problem but we will see when I get out to test it. Hopefully there will be a day before ice up. LOL

    Over heating problem. need help

    My understanding of the poppet valve function is to allow excess water pressure to be dumped directly to the exhaust. I imagine if it had a week spring and was opening too soon it could cause this problem. If I am wrong with this someone please correct me.

    outboard was very hard to start after sitting a while then smoked a lot

    I have a model year 2000 200 EFI Merc. It sat for a month or so. I took it out to the lake to test a new kicker I had installed. When I went to start the 200 it ran very slowly and would not allow any additional throttle or it would quit. After a few of these starts and stops it began to...

    Over heating problem. need help

    I have a model year 2000 200 EFI Mercury outboard. This past August I was on Sturgeon bay and the water temp was in the low 70s. I was just cruising along a about 3000 RPM and the over heat warning horn came on. I looked at the temp gauge and sure enough it was at about 210 degrees. The...
