winterizing question?

[bones774]

I put the muffs on and turned on the water then climbed up into boat, started it up and started to pour fog oil down carb until she stopped. I then climbed down and walked over to hose spigot and turned water off,(maybe 3 minutes) then drained block as per instruction. Now i'm starting to worry that leaving the water on as long I might have filled cylinders with water, did I make a mistake here? I usually have someone standby and turn water off as soon as engine dies.Thanks

Shouldn't cause a problem at all.
If you REALLY want to check it, just crank the engine over, no need to start it. Water in the cylinders would hydrolock the engine and it wouldn't turn over.

Re: winterizing question?

Well, I'm not sure how the water would get from the hose/muff into the cylinders. Since you have a 350 magnum, it has a sea water pump and that will not let water pass it unless it is turning via the engine. So, the water from the hose just spits out of the muffs for that period of time when the engine is off.

No worries, but Like Don says, give it a crank or two just to check.

Re: winterizing question?

I was thinking about a quick crank but was worried about impeller with no water thru muffs, and if i muffed then I would have to drain all over again.

No one said hook up muffs and turn watere on, just crank the engine over a few turns NO water.

Re: winterizing question?

Is this an alpha or a bravo outdrive?

Assuming it is a Bravo with the 350 Magnum . . .

You said that you were winterizing, but you ran water through the engine. The sea water pump and related hoses have water in them. They drain ever so slowly and may won't drain completely. So, are you really winterized? or are you planning on replacing the sea water pump and the oil cooler next year?

The seawater pump still has water in it unless you specifically disconnected the hoses and drained it.

Regardless, the impeller can take a crank or two whether it is an alpha or a bravo.

Re: winterizing question?

It is an Alpha, I drained according to owners manual which does state to remove those two lower pump hoses and power steering cooler hose.
I know no one said with muffs on but i've read over and over again how quick you can toast the impellor with no water.

You only have to turn the engine over a couple of revolutions. No way in HELL can you damage an impeller doing that.

Re: winterizing question?

You should be OK, and you can crank the engine over without concern (just don't start it)

I still don't understand how you would have water in the cylinders.

Re: winterizing question?

i just wasn't sure, i've heard how water can backflow thru risers into cylinders but didn't know which engines. it sounds like you are pretty sure, so i won't worry. just figured id ask to be sure.
thanks

Ayuh,... That can only happen if ya have faulty manifolds, or risers...

There are a very large group of people on these forums that have no first hand experience with a subject, but post because they have read things. Then they repeat it, but usually change things a bit or add what they think might happen, not realizing that that information is there for everyone to read. So yes, you can read a lot of things on the internet, especially in forums. But you have know way of knowing who actually knows, and who is posting only an opinion.
All you have to figure out is who actually knows, and who is just raising a post count and sounding like they know what they are talking about.

Re: winterizing question?

wait wait
everyone knows if you run water with muffs you will blow the water pump seal....
the bell housig has to come off!
my machanic says this is an 1800.00 doller job....

No, everyone doesn't know that.

Find a new mechanic, yours doesn't know what he's talking about.

Re: winterizing question?

Just wanted to support what Don said. I will always include that "this is only my opinion" or "just throwing ideas out there, don't know if that is the problem". By making it clear I'm just throwing something out there, my idea will either be confirmed or invalidated within the next couple of posts. Of course it's rare that I get a chance to offer help in the I/O section. Our mods here pretty much can answer anything given a proper description of the issue.

Good luck with the winterization. Turning a wet impeller with no muffs will not do any damage in the first couple of turns. This I feel pretty confident about. Maybe if it was bone dry??

don s. , is just saying don't listen to everyone.

Re: winterizing question?

Truth is I actually hook the garden hose right to the intake house before the thermastat housing.
Then I let her run, bypasing the water pump in the lower end all together.
This way if their is a ? spot in the cooling system it is easily found, and can be fixed.
and no even doing it this way their is no way water can get in motor unless u have a mutch bigger problem.
the minamal psi from the garden hose will not hurt anything.
That being said the post from earlier was a joke, and proof that any can say anything in a forum, So yes never take to heart what you read.
Allthough their is a lot of smart peaple in this forum that do know what they are talking about!!!!!!!
