winterizing question
I have a Donzi Regazza with a 5.7 Mercruiser. I live in the Northeast and
the boat will be shrinkwrapped outside. I'm debating two things. Should I
leave the tank (Metal) full with gas and add stabil or should it be empty?
Also should I drain the engine from coolant (raw water cooled) or run the
"pink stuff" through it until it comes out? Thanks in advance. David |

| Fill the gas and stabilize. Drain the block,risers,water pump, and risers,
then fill with the pink stuff or something with metal protection.

| We should start a FAQ for rec.boats. There are a lot of opinions on this subject. In your case, with the
metal tank, I'd take it down to near empty (leave 5/10 gallons), use
Sta-bil for a full tank and keep it capped but vented. I'd also vent
the shrink wrap tent to keep air flow constant. >Also should I drain the engine from coolant (raw water cooled) or run the

| I have an unusual circumstance this year with regards to winterizing the
Navigator. I purposely have not started the engines since they were
winterized last fall. I figured I'd save some money on winterizing this
year but, at the recommendation of one of the diesel techs, they will be
fired up just to circulate oil to all the bearings and turbos, then
winterized again with fresh anti-freeze. I used the generator, so that
will have to be done along with all the water and AC systems. We are going
to wait until the first week of December however. The GB has been used, so it needs the full treatment anyway. It will be
hauled at the end of October and stored inside. The Navigator will stay in
the water again this winter. Eisboch |

| Opinions differ on leaving the tank full or not. I chose full with some
sorta stablient. Our boat has a 5.7 efi merc engine (2001). As far as the block I drained there are five drain cocks on it. They are
blue in color. They are located near the center of the block. The
outside ones are easly visiable. The other two are just inside and under
a little further. It is easiser to feel them then to see them. The fifth
is located under the left side of the engine under the water pump. After they are drained and replaced you will see four hoses connecting
to the front of the block. I then disconnect the front right hose and
fill the block with antifreese. It took a little over a gallon and I
could see it running out the drive leg. You can also here it filling un
in the block as you pour it in. It only took about 15 minutes to do. I was going to use the muffs method. But the local marina teck suggest
this as a better way. He pointed out that just using the muffs. The
engine needs to be warned up to open the Thermostat. And even then it
opens just a little bit. Not allowing a whole lot of antifreeze in. Capt Jack R.. |

| I suggest that since you seem to lack experience, you take it to a
reputable dealer and have it winterized there and have the other
regular maintenance done at the same time. I witnessed at my local
marina this summer the result of an improperly winterized 5.7 (efi) ...
what a shame. |
