through-hull drains

Post by chugalug » Wed May 30, 2018 6:16 pm

I'm thinking about installing a hull drain in my Bo-Jest build.since the lowest point is up in the v-berth area-it would have to be a through hull fitting with a plug.I'm thinking on a bronze fitting and screw in bronze plug(if I can find such a critter)It would be open only while on trailer to drain rain water.Any suggestions?Perhaps a Garboard fitting from Glen-L would work.I'm just a little hesitant about drilling a hole.

Bill has stated several times that his garboard drains leak.

I'm planning remove the garboard drain and plug the holes. they seem to act as a one-way valve in. I'd rather rely on the pumps alone than let water in for the pump to get out.

I agree with Bill. Put a good pump down there and Jack up the trailer tongue or find a good slope to raise the bow up to drain the bilge out the transom drains.

I didn't install transom drains as hull is shaped like this

You could at least pull the transom drains on the boat ramp and it would probably drain there?

I have attached a picture of what might work for you. Classic Chris Craft boats had a drain in the bottom of the boat. The picture is of the thru hull drain like the chis craft boats used. David at Classic Boat Connection said they sell new reproductions that are manufactured by the same foundry that Chris Craft used. He sells them for $58. His phone number is (507) 344-8030. This is a picture of one he has in stock.

:D Thanks! saw one -similar concept for 116 bucks at Hamilton marine.Still haven't decided to drill hole yet.I tried to block off vent lines in enclosed bulwarks so rain water might bypass and drain out back vents.Thought a driving rain might enter hull during extended trailer stays and accumulate. :D

I can guarantee you that transom drains are useless on the bojest. During construction I had considerable water in the bilge on mine, and I jacked up the trailer as far as it would go, and then drove to the steepest hill I could find - neither method got the water anywhere close to the drain plugs. Not one drop. I used a shop vac.

Just before I sold it, I had water get in again (a grandson with too much free time) so I drilled a hole in the lowest point and the buyer said he’d put in a plug.

If you're only doing 8 knots how about a regular brass tube with a rubber plug in the bottom? Bad idea?

On my Monaco, when it is level the lowest point is about where the drivers feet are. It would be hard to lift the front high enough to drain at the transom. I have a T- handled garboard plug like Jim posted. It is under the front cockpit floorboard on one side of the keel with a limber through the keel to drain the other side. Works great, it is a tapered thread, no leaks.
After I pull the boat out pull the plug and drive home it just takes a couple paper towels to dry it out.
