I have a rinker 270 with the 350 mpi. Nice little mini cruiser. It has a hot water heater that runs on shore power but is also warmed by engine coolant, I think.. The motor is a closed system and is a 2006 boat.
I recently replaced the fresh water pump and also a faucet that is in a small sink behind the helm. It is a cold faucet only.
While on a run, I turned that faucet on and it was scolding hot. First thought would be that internally the water heater is done and water is mixing from the engine and going into the water system- but I'm closed cooling so isn't that coolant vs water? It for sure was not coolant. This new faucet also is barley working- all the rest work fine. Someone suggested that the faucet has a clogged screen- i will look but not sure that faucet has one- but it was just installed and worked fine before I went in the water....so am I being told wrong on the coolant not vs engine water? The only water available from the engine would be from the heat exchanger...always something!

Could be the hot/cold lines go swapped
