what all do I need to do to winterize
Went from a Z200 with 5.7 and alpha one to a Z272. Firstly what do you do about the 2 sinks and water supply as well as the transom shower? Then i am assuming fuel/water separator, filter, engine oil and filter, drain block, power steering cooler, but what about the bravo 3? water pump?

mike ,
I have not done any witertizing of the potable water system on a large boat. I use low pressure air to blow out my RV water system every year though. One of the guys with the "big boats" will chime in. :) I hate this time of year due to winterizing , extra cleaning , and especially it's the end of the season for yet another quick year gone by to fast :( Larry |
Re: what all do I need to do to winterize
My Z280 has three sinks and the transom shower. Best way to winterize them is to run the pump until the fresh water tank is empty, then pour a few gallons of RV antifreeze into the tank, run the pump and open each faucet until the antifreeze flows out of the faucet. I do the same for the transom shower.
As far as the motor goes, I follow the Merc manual. The B3 water pump is located on the front of the engine and both hoses must be removed from it to allow the water to completely drain out of it. It's a lot more work that my old fresh water cooled Alpha 1. |
Re: what all do I need to do to winterize
I do what Steve said for my fresh water system.
After lots of worrying and research about the engine/drive. I now just pull the 5 drain plugs, drain, replace the plugs, then suck up 3 gallons of RV antifreeze through the drive. I've had a handful of pros tell me this is what they do. I have a 5 gallon bucket I sit on my swim platform with a hose coming out of it attached to muffs. Ideally, you'd run it up to the temp where the thermostat opens but that never seems to work on the hose for me. The best thing to do is probably remove the thermostat during the process. The pink stuff right now is about $1 cheaper than it will be later so I like to stock up early since I typically winterize more than once. |

We do have winterizing tips & procedures in our Maintenance section....
