Hi long time lurker ... 1st time poster .. woo hoo (I guess being in precautionary covid isolation has some advantages!)

Had a very similar situation on my delivery voyage, Grand Haven to Lk Ontario.

Turned out that the coolant was leaking from heating coil in the tucked away potable water heater. Easy to by-pass this circuit to check.

When topping up the coolant, venting using the system using the vent valve (aft left of expansion tank, engine at idle and cool), really sped up getting the cooling system purged of air and truly full.
