Author Topic:   REVENGE 20 W-T Water Freezing

floater88 posted 10-31-2011 12:23 PM ET (US)
I drained as much water as I could out of my Revenge 20 W-T, but [I am] sure there is more waaaay down in there somewhere. I put an in-line fuel pump on a hose down into the space where the control wires go and got some out of there. I popped off my three deck covers and couldn't get the hose down into any of them [due to] of the gas tank. What kind of damage may this water do when it freezes down in the bottom of the hull? I'm up in Toronto, Ontario. Boat is now covered in three tarps and waiting for the snow.

You may consider to store your boat in a heated garage for the winter months. This would give you a chance to do some work on the unit and to get to the bottom of you water intrusion problems. I have known of some Whalers having shed a lot of water over the few months being stored and worked on. This is not an instant solution and you will have to work at it.

Water sitting in low places in the cockpit will just freeze like water in an ice cube tray. When is the last time you went to the refrigerator and found the ice cube tray has been split or damaged by water freezing in the low places?

If you are concerned about water you can't remove, try adding some RV anti-freeze to the it. The anti-freeze will prevent the water from turning rock hard and may buy you some time until you can determine how and if you really need to remove it.

Well Jimh I have never owned a fiberglass boat before and i'm a little concerned about ice and the hull. I figure it will expand upwards as there should be room for it but it never hurts to ask a question does it? Thanks for the replies

The "space where the control wires go" is a sealed off portion of the hull liner that leads to the cockpit sump. There is a drain in the sump which will remove most of the water.
See the owner's manual for recommendations on the drains and the drain plugs. Here is a link to an owner's manual that I converted to HTML and published:

If you have a few ounces of water in the bottom of the cockpit sump you should not have a problem if it were to freeze--it's like water in an ice cube tray. Of course, it is not a good idea to leave water in the boat over the winter if you can avoid it. That's why usually all the drain plugs are removed and as much water as possible is drained out.
If your fuel tank cavity foam lining is saturated with water and holding several gallons of water in suspension in the foam, you might have a problem--but you're not going to be able to fix it easily between now and the onset of winter. Once foam is saturated with water, the water is rather difficult to remove from the foam. See the FAQ on this topic:
http://continuouswave.com/whaler/reference/FAQ/#Q3
Boston Whaler boat hulls where there has been ingress of water, where the interior foam is saturated, and where the hull has been exposed to many freeze-thaw cycles will typically see de-bonding of the foam from the laminate, as well as possibly other problems. The expansion of water when it freezes will likely tend to crush the foam, breaking it down some more. The hull structure should be much stronger than the foam, and the foam ought to give first, long before the hull is compromised. The problem with water freezing in the foam is destruction of the foam air cells, creating a larger void where more water can collect in the future.
If you want to fix water in the foam, you will need to start with the boat in a heated area and be prepared to do some serious work.

Hey that is great info. THat is what i've been looking for. I got all the plugs pulled and tilted the boat up from the front and even more water came out. I should be good to go now. Thanks for all the help.

I have the same model as you do and my boat freezes every winter, tip the front up and if possible put a board or something under the wheels on the port side to have any water drain towards the sump side of boat. You done good. There are pictures in my profile of my floor removed in my Revenge, there really isn't anywhere for water to sit, and the foam is pretty water resistant.......Jack
