VP manual says to drain the raw water pump (the one with the impeller). Then it says to drain the supply pump, and shows a diagram of the raw water pump & its two hoses.
Just confirming this is a redundancy in the manual, and not a mistake where one of the pump draining set of directions should be for the circulation pump?

Somewhat related, does the oil cooler need to be drained of water or does it drain out when the raw water pump lines are disconnected?

Thx

Just found the operator’s manual online. It says to remove the hose from the circulation pump. The workshop manual does not contain this tidbit.

Question stands on the oil cooler; does it need to be drained uniquely / separately?
