Hi there, I used to have my '92 BFN winterized at a marina. This year, I have the boat stored in a barm and do the prep myself. Already drained the block (2), headers(2) and pump(1). And want to pour antifreeze in, but are not sure which hose exactly to use. Other question is on the (Walter) V drive: do I need to drain this as well? And if so, by disconnecting the hoses or by a drain plug. Many thanks in advance from a very mild Holland (68 degr. F, new record for November 1).! ------------- '92 BFN |

Pull the water hose off the walters on the port side of the boat. I'm not an anti freezer, pull the two hoses off sea water pump, and large water pump hose, if you can move the boat find a steep grade and lower the bow as much as possible wait several minutes then elevate the bow as much as possible and wait til she's done dripping. Don't forget the trans cooler and strainer ------------- Brian |

| I always add a/f through the large hose connected to the circ pump. That will fill the engine from bottom to top. |

Thanks for your reactions. I poured the A/F in the thermosat housing; about a litre came out of the exhaust. And disconected both hoses from the V drive and from the raw water pump and let the water out. All set for winter. ------------- '92 BFN |

Don't forget the trans cooler. If it's mounting position doesn't allow draining when you disconnected the hose on the RWP. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

How much did you pour in, should have held 2-2.5 gallons? |

Yes, RV antifreeze is cheap but it always amazes me everyone trying to fill up the complete system. Drain only is a viable option and many do use the method. With a complete drain, all that's needed for piece of mind is to hit the low stops with the RV that still may have water present. I, in all the years have NEVER used more that a gallon and have NEVER had a problem! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Sounds like you are one of the "try to fill it up winterizers"!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

^ pulling the hose off the RWP side in most applications accomplishes this. Follow the hose(s). Look for low spots. Gravity works the same on all cooling systems. Water trapped in cast iron is bad. A little ice in the bottom of a rubber hose won't hurt. I had to thaw out 2 hoses Saturday to get an 88 PCM bbc sucking water. I've had to do the same on an 88 PCM sbf. Rested the clogged hoses on my car engine until the ice slugs fell out. Harder freeze than I anticipated. Cost me some time but no damage. ------------- |
