Author Topic:   Drain Tube Install?

Ok, I know some listers have installed drain tube replacements. How does one flare the brass tube in say a 15'? Not much space to work in from the inside... Looking forward to the answer to this, before I order the replacement tube. Anyone know the longevity of the plastic replacement tube offered instead of the brass? My drain tube watches the sunset every afternoon in Florida, so I know how long brass lasts. (16 years).
Thanks from the drydock...

Go for the new plastic ones. They will outlast the brass and are much easier to install.

Dick: I understand the new plastic drain tubes require a bigger hole. What size, and how is this larger hole accurately & best accomplished? Is the original hole 1"?

Where can you get the longer sizes, say 5".

The new drain tubes are slightly larger and you have to drill out the holes to fit.
The tubes are only available through Whaler dealers. No aftermarket tubes are long enough.

Dick - thanks, but how does one enlarge this hole for the larger plastic tube, inside and out, and what diameter is needed? I can't figure out how to do with conventional drills or hole saws. There must be some secret technique you know about!

What about enlarging it my grinding?

If I remember coorrectly it doesn't take much. It would probably be best to use a rasp or small grinding wheel in an electric drill. Then bed the new one in with 3M 4200.

There was an older thread someone wrote- he made wood plugs as guides and then a hole saw to the proper diameter. You should only have to go about 5/8" deep before you hit foam, the new tube should be able to be "pushed" through the foam.

Thanks for the info. I need to install a new one in the bow locker of my 18. I think I'll try the plastic version. The original one didn't corrode, but simply came un-crimped on the outside, losing the o-ring gasket. I also discovered that the factory omitted the protective Perko cover, which allowed the fitting to take a real beating while the boat was under way.
