We purchased hull #4 this Spring and had the BEST Summer ever on our local reservoir. The only thing that surprised us was the slosh of water we get from the swing keel cable tube. It happens when we back out of our slip and if the weather is strong while we are in the slip stern to. How you you experienced C25, swing keel owners stop that water? Thanks

Hi Ireddin, I am not experienced by any means as I just bought the boat yesterday, but I looked at that today and thought I would just shove a soft natural spong down the hole. Cheers.

I used a sponge to plug the cable tube on #1205 for several years, then at the last replacement of the cable, I capped the hose with a PVC pipe cap into which I drilled a 1/4" hole to pass the cable through. The pipe cap was a 1" size if I remember correctly. Once the cable is passed through the hole in the cap, insert the cap about 3/4" down into the top of the hose and secure with a hose clamp. If you drilled the correct size hole, the cable will be a close fit through the hole and this will stop all but a fine spray of water. To stop what little water still manages to come through the hole in the pipe cap, wrap a towel around it. The towel will get damp, but that's preferable to getting your quarterberth cushions wet.

I used a rubber sink stopper with a slit in it that fitted snugly into the tube. I also capped off the top of the tube with several pieces of duct tape once. The tape worked but not as long as the sink stopper.

Best of luck with ol'#4

I guess my hose must have been long enough, it never happened to me. I thought this was a launching phenomenon only, where the angle and direction were just "wrong".

I think the keel cable hose perculating problem is caused by air pressure in the keel trunk. This could be the result of ramp launching angle, extreme wave action, or air being pushed under the hull by an outboard prop sucking air or exhaust in reverse (and pushing that aeriated water under the boat).

I like both the PVC cap and split stopper solutions. As you can see, they both have in common restricting the area air (and water) can blow through around the cable. The turning ball provides considerable restriction down lower, so the upper spray stopper probably doesn't have to be an extremely tight fit on the cable to work.

An added benefit, especially for boats in saltwater, is reducing the amount of water splashed up onto the steel keel winch. Those winches dissolve fast enough without any such encouragement!

This my be a little off topic, but since I bought my boat "as is" in a cradle, I can't figure out how the stop latch on the keel winch works. I don't see any kind of latch from keeping the keel up when in the water. Cheers.

The stock swing keel winch is 'automatic'. There's a built-in clutch/brake that prevents the winch from letting out cable any faster than you are turning the crank. When raising the keel, you will hear the clicking of a rachet similar to a trailer winch as you might expect. When lowing the keel, the crank will first resist turning, but will then move easily and silently in the opposite direction of rotation. If the condition of the winch is questionable, then replace it. Catalina Yachts has them in stock for a little over $100 (a mere boatbuck and change).

Ireddin, you're not the lone ranger...er..uh...skipper. I have the same problem and I've opened asked the same question several months ago. My dilemna was that with my old 2 stroke 9hp I didn't have that problem. Then I got a new 8hp high thrust Yamaha and discovered a fountain when I was in reverse. It's a natural occurance when the prop wash gets thrust into the swing keel cavity and has nowhere to go but up!

I've solved the problem thanks to the great folks on this website. My first attempt was the "stuff a sponge" down the hose. The problem with that was..when you crank up the keel, many times the sponge comes with it. Then someone suggested a PVC cap with a slot and hole in the center for the cable. It did the trick. The cap is larger than the hose so it's not tight. It is simply heavy enough to hold down the "fountain like" flow upward. Simple solution to a perplexing problem. I also liked Val's suggestion of the rubber sink stopper. It's just good to know you're not the only one trying to stop a gusher and protect your quarterbirth upholstery.
