Just bought a boat at the end of this season after it had already been winterized. Therefore seller de-winterized boat, we took it on a test ride and then he had the "mechanic" re-winterize. He supposively hooked up muffs with antifreeze and then fogged the engine. I think the "mechanic" is a friend of the sellers. Therefore I would like a little extra piece of mind knowing the boat is properly winterized, since I prefer to do it myself or know who I am hiring.
So for a little piece of mind, I decided to do some extra steps I saw on youtube. I would like someone to verify that the hoses are the correct hoses and my procedure is not damaging something.
- Removed large hose #1 at thermostat. Pour AF down big hose until it filled up block and came back out the thermostat where I had remove the hose from. Re-connected hose.
- Removed hoses #3 and #4 which go to the risers. I poured about 1/2 gallon of AF in each one before running out. I never heard it drop out the exhaust.
Engine is 97 7.4L. I also just replaced the oil, oil filter and outdrive gear lube today. Do you know how long it takes 7 quarts of cold engine oil to get sucked up one of those vacuum extraction pumps in 40 degree weather? I do: 4 hours!
