will it keep the water out if the water is above you knees

No. They are designed to keep water out below top level of boots. The strap at the top will tighten to keep boots snug, not water tight.

Yes it will but it has to be lowered all the way down but I don't recommend this cover I bought the support poles with the cover and it still held water and ripped

I have mine positioned under an eave and I've never noticed water coming over the top.

Yes it does. But I have only used it during rain. Never actually used it under water

As long as your swim deck is far enough out of the water so that when you tilt the outboard it is high enough to clear the water.

You would need the 17-19 feet cover so far no water has seeped through as Marshall has recommended do what you can to prevent water puddling up

Yes it does a good job keeping water out. The lid overhangs the frame and water does not enter. It is important to keep the unit level or tipped forward slightly so that water rolls off top toward front. If the unit is leaning toward back water will puddle on top and can leak into box. If you set the unit properly it stays dry.

No. The water will ask through like a thin wetsuit. It is useful so you don't chafe if surfing or as sun protection on a dive boat or while swimming.

The mats do have a lip all the way around and yes,, the holes would let water out but I have yet to get that much water in the mat.

Will keep rain off. But if you drop it in the pool it will get really wet. Hope it helps.

Yes, if you keep it zipped all the way it will keep out snow and rain. However, you will get condensation on the inside.

Yes in that it will keep all moisture off the seat itself. The backing is waterproof, but fabric "top" can absorb water.

Yes. NO water gets through the one I have. It will actually puddle up in the lower areas.

We have ours hanging over our deck. It is woven material that does have gaps between the 'threads'. However, it doesn't necessarily fall uniformly through the cracks, ours tends to primarily pool in the middle and then drip through there. We have it mounted level at the 4 corners. I suspect that if we mounted at an angle that most of the rain would shed off the edge.

It is porous and does let water through. Being under it is better then nothing but it will not act as an umbrella.

As long as it is pulled tightly, it keeps my patio dry. Mine has been up through many showers and the patio underneath had stayed fairly dry. Of course, it does get wet around the edges when the wind blows the rain under. Also, you need to be sure to have it tilted slightly to let the rain run off.

I think it would. The pressure behind the bladder should push all the water out even if it's in a horizontal position. Hope that helped.
