I have a 115 Chrysler. When I advance the thottle, It's seems to have a rough spot or vibration between part thottle and idle. Do I need to adjust the idle mixture or is that normal for a Chrysler outboard? My second qustion is when I am at cruise, the temp is stable,(135 to145)but when I go to wide open thottle, it slowley whant to get hot. When I back down off the thottle, temp comes back down or I stop to let it Idle to cool down. I have done all of the Head gasket, New water pump, check for blockage in the channels and by-pass valve. I have a 110 thermostat. That might be to cold because the water in the river is very hot this year. N.C. As soon as I start the engine, in about 2 1/2 min the thermostat is opening and never close the whole time(2nd new 110 thermostat) which result in low water pressure on the gauge.(no resistant) Manual says it should be 140 temp Thermostat.If the Engine is to high on the transome, will this cause this problem? Any help woud be welcome.
