Johnson temp light problem

[PierBridge]

64 johnson 75hp....temp light come's on, have replaced the T stat, water pump.<br /><br />with the old and new t stat we were getting some water out of the exhaust, today we tried with out the T stat and we have no water exiting the exhaust. we blew air through the t stats hoses and it does not seem to be plugged.<br /><br />At idle it's over heating in a bout 5 minutes the cyllinder temps were 222 and 232 i'm guessing the light comes on about 220...?<br /><br />Engine starts and runs well.<br /><br />were thinking something must be blocked in the lowere unit.<br /><br />any ideas?<br /><br />Thanks Pier.

Make sure the tube from the water pump to the engine block is inserted properly.

I noticed the o ring in there was torn apart i have new one and will make sure it's connected properally.<br /><br />compression is 100, 95, 92 , 90. Does that sound OK for 1964 85 hp????????

Compression sounds OK.
