  1. I ran the engine for 10 minutes with water, then drained the block and manifolds (but not the heater hoses), then restarted the engine and sucked four gallons of coolant in then shut it down. Sounds like I just need to blow those hoses/heater core out with an air compressor and be done with it.
  2. Just winterized my 2012 Centurion Carbon Pro with 5.7L PCM 343. Question is how do I know if the antifreeze reached the heater core? I'm always concerned because the last boat I had, Malibu Response LXi with Indmar engine, 2 out of 7 years the heater core froze and busted even after putting pink antifreeze through the system the same way. Is there another way to make sure there's no water left that will freeze?
