So I have been spending as much time as I can on the boat during the current crisis. Today I did some more run tests on the 1GM10 install looking for unusual vibrations, things moving that should not, and things not moving that should. Checking for chafing of wires or hoses and making adjustments as needed.
After running the engine for some time it got up to almost 140 degrees as measured at the installed temp sensor, but the coolant entering the heat exchanger, as measured at the fitting at the top of the engine shows 86.9 degrees.
When I had the Palmer p60 installed I had a car heater in the cooling loop and it would really warm the boat up when the engine got up to temp.
It seems on my fresh water converted 1gm10 with 44 degree seawater I will never be able to warm up the cabin.
In the photo attached the old analog gauge is connected to the 1gm10 temp probe and the digital probe is attached to the metal fitting where the water exits the engine after cooling.
It is starting to look a lot like I can no longer get enough waste heat to heat the cabin while underway.
It would seem there is enough coolant bypassing the engine that when mixed with the hot coolant out of the engine the temp at the junction of the bypass and engine out is just going to be too low.
Ideas?
