There are water drains in the transom shield but not on the drive itself.

Look at post#10 in this thread,

Re: Omc Cobra Outdrive

I was told by a 30 year pro that the way to winterize the water passages in a Cobra drive is to pour antifreeze into the water supply hose from the drive (usually at the thermostat housing) until it comes out of the water intakes on the drive. Sure beats truing to get those screws out.

Re: Omc Cobra Outdrive

Thats the way i always done it.I never removed those screws..
Drained the block,manifolds and PS cooler then filled all the hoses with AF until it runs out of the drive....easy..

Re: Omc Cobra Outdrive

yeah, that sounds better!!! there is no motor in the boat I am getting a new one for it. Them power steering coolers, are they a must have?? mine leaks water and thay are like $75.-$100. for a new one. A buddy of mine has a 24 foot cabin cruiser with a 350 in it and he does not have one. Another one has a 19ft Rinker with i think some v6, and he said he dont think he has one?? So, do I have too have one??

I would take it to a radiator repair shop and see if they can fix it.
Not sure if you can get by without one.

Re: Omc Cobra Outdrive

i dont think it would get so warm that they would need a cooler for it??

Re: Omc Cobra Outdrive

Is that what that thing is? I have a 1990 Chriscraft 198 Concept and there was tube about 3" in diameter and 8-10" long that froze one year. It was way behind the engine and I had to pull half the boat apart to get to it. Once it was out, the guy at the marina who told me what to do tapped on it with a hammer for a while and resoldered one end of it. I put it back on and it was good as new. Under the black paint it is all copper.

Yes, that is the power steering cooler, and at times they can be mounted in very hard to reach places. You may want to relocate it along the underside of one of the exhaust manifolds - along the block. Some engines have them mounted there.

Re: Omc Cobra Outdrive

yeah, I was thinking about doing that too. its just the top cap that poped out a little, and leaks a little water. I was just askin why I have a power steering cooler in my boat. That fluid dont get that hot!!??

Re: Omc Cobra Outdrive

Its on there for a reason...i would fix it or replace it rather than taking the chance of running without it.

 

[medalist1901]

Re: Omc Cobra Outdrive

im going to just fix it!! because I dont feel like finding a fiting or something to put the 2 power steering lines together, plus if its there its there for a reason

Ayuh,...It would if there Wasn't a Cooler....

A buddy of mine has a 24 foot cabin cruiser with a 350 in it and he does not have one. Another one has a 19ft Rinker with i think some v6, and he said he dont think he has one??

Your Buds don't know what they're talking about....

If the boat has P/Steering,..... It has a Cooler...

Re: Omc Cobra Outdrive

OK, I just got off the phone with one of them, he said one of his boats does not have a cooler, the other one does not they both have power steering. im on the other guys boat right now. NO COOLER for the p. steering. Well, turns out that my bud's do know what they are talking about, cause these two boats do not have p. steering cooler, on e of them DO. All im asking is "do you need to have one" he has owned this boat for 9 years, and is runnig it w/o a cooler, he sais he has never had a problem with the power steering. I am going to get mine fixed, i just wanted to know if you need one. But thanks for the advice! Bryan

Re: Omc Cobra Outdrive

The way I figure it, if they could have gotten away without it, they would have. This way they could make more money. Instead, they decided they needed it, so gave up some profit to put one in.

I am keeping mine, no matter what a pain it is to get at and fix.

Re: Omc Cobra Outdrive

oh, for sure, if its in my boat im going to get it fixed or get a new one

Re: Omc Cobra Outdrive

On the right side near the bottom is big screw. thats the drain plug. The one near the top is the fill plug BUT fill it from the BOTTOM, not the top.

Re: Omc Cobra Outdrive

Besides this being a 2 year old thread, you just gave wrong info about filling a Cobra drive. They get filled from the middle plug.

Is that how u filled yours? If u did, you'll only do it once.
