Why does my air conditioner keep blowing cold air?
Heater valves: These valves control the heat output of the heater core. They can be mechanical or vacuum-operated (like a rotary knob that you turn) or electronic (in electronic climate control systems with specific temperature settings). A valve that is stuck in the closed position will prevent heat from entering the cabin.
What causes an air lock in a hot water heater?
Air lock: An air lock is a large air bubble that forms in your cooling system as the result of a coolant leak or a recent coolant top-up. An air lock prevents the coolant from circulating properly and can cut your heat output. Solution: Set the heater to its maximum setting, remove the coolant tank cap and fill it to the proper level.

What should I do if my MerCruiser engine is too hot?
Usually, when first started, it is a good idea to watch the gauges and monitor the temp. Watch the temp gauge as the engine warms up. The temp will usually climb just a little above the normal operating temp and then it will drop down a little when the thermostat opens up. That is normal and it confirms that the therm is opening OK.
How to check engine temperature after a drive?
To verify the actual engine temperature, check if the top hose to the radiator is hot after a drive. Thermostats normally open at around 80-90°C and the hose will only get hot once the thermostat has opened. Point is that the sensor is reading fine at low temperatures.

Compression, you’ve nailed that one down, all looks fine as far as ring seal. Ignition, still undetermined, DVA testing stator output and/or verifying spark on all cyls when the problem arises still needs to be done. A motor can rev freely UN-loaded, but as load raises so does the demand for a high intensity spark.
