Could it be a leaking drainplug?

    New to the forums here so apologies if there are threads that address this already. I recently bought a 1977 used boat. We completely refurbished the hull, sanded, filled in dings, etc. with Evercoat Formula 27 and then painted 2 coats with Pettit Easypoxy paint. We repaired the surface cracks in the deck with Gelcoat repair. We also pulled the two ports and reseated them with silicone sealant, as well as pulling all hardware off the hull and reseating it with new silicone sealant. The maststep appears solid and original as best I can tell. After all our work, our boat looks brand new and we launched it yesterday. Great fun!

    After about 3 hours in the water, we pulled the hull drain plug and about 1/2-1 gallons of water came out. The boat is older and does not have an autobailer installed, just a cockpit drain plug which I plugged with a rubber stopper. When we were refinishing the bottom, I noted that the plastic cockpit drain assembly appeared loose as I could turn it, but was unable to unscrew it to remove and reseat it.

    My question is this... is this my likely culprit leak into the hull? If so, does anyone have any recommendations for resolving this? Should I try to pull it off and replace the fitting? Just bead it with silicone against the hull? Other ideas?

    If that's not my likely culprit, do you have other common places I should look for leaks and any recommendations on how to find them? I really feel the hull and deck are very solid so that's why I am focused on the drain plug.

    Thanks for your help. I found these forums to be incredibly helpful as I was researching how to refurbish the boat...

    Hi Barts,

    If the fitting in the base of the cockpit is plastic (and it is loose) it is likely that is has failed completely and is the source of your leak. The replacement bushes are made from brass and do a much better job in this area than the plastic ones (I had a plastic one on my first boat and this leaked badly until i replaced it).

    APS list this as follows but other dealers may have it in stock: http://www.apsltd.com/p-24102-cockpit-bush-assy-brass.aspx

    When you fit the new bush you will need to ensure you seal both sides using a good quality flexible sealant as the cockpit and hull do move around a little.

    Did you check the hull/deck joint (the rails and the inside of the daggerboard case) ? Those would be other potential leak points, as well as the drain plug in the stern.

    You can use soapy water and a little air pressure to pinpoint the leaks - search the threads here for the technique

    Thank you guys for the tips. After looking at the 'rectal shot' and related thread, I do suspect this is a major culprit. I'll order the brass bushing.

    Do you have any recommendations for removing the plastic one? I tried to unscrew it when we were refinishing the hull and it wouldn't give (granted I didn't get too 'Terminator' on it as I didn't want to break anything). But, is it a screw fitting or a compression fit? Should I just grab a pair of pliers and go nuts?

    Thanks again,

    Barts

    the plastic bushing pops off... you will need to take a screwdriver to it... and also can you post a picture of your boat??? i am quite interested in how the petit easypoxy turned out!!! :D

    Seems relatively durable... time will tell. It was recommended by West Marine for the job.

    Looks great, but I see a bottle port aft of the cockpit, wouldn't the tiller run over the head of the bottle?

    Where did you find a brass bushing? I'm not having any success with that, everywhere "backordered".

    Wow nice job on the hull!

    That amount of water sounds like it could be the bailor fitting or maybe hull drain plug, don't trust anything just because its new, even when sealed properly sometimes things just leak,

    Even the new hulls leak sometimes, the dealers take all the fittings off and reseal them, usually works

    Replaced the cockpit through hull fitting and that solved it!! Also have an inspection port aft of the cockpit so went in and applied Boatlife caulk (strong stuff from West Marine) all around the joint between the hull and cockpit. Then seated the new fitting in with Boatlife as well. Worked like a charm. Sailed several weeks ago and no water leak!

    Benjamin, I had the same problem so ultimately contacted Laser Performance directly. It was backordered there as well but finally shipped a couple months ago.

    Thanks everyone for the help. We named the boat Phoenix and had a great time. Here's a picture of her in action...

    Welcome to the new Laser Performance method of running their business. Carry only enough inventory to build new boats (most of the time), let dealers fend for themselves for spares

    Not sure who you have called, but start with the bigger dealers:
    APS www.apsltd.com
    West Coast Sailing www.westcoastsailing.net
    Colie Sails www.coliesails.com
    Kolius Sailing www.kosailing.com
    Svendsens - www.svendsens.com
    Dinghy Locker - www.landfallnavigation.com/dinghysailing.html
    Tackle Shack - www.tackleshack.com

    Throw in a Candian Dealer as well

    Thanks for this, Tentmaker. I'd already called some and struck out, there are others you don't have here I called without success, some here listed I'd not seen before, and finally struck gold with Kolius. They had but one, and I snatcht that one up right off.
    Every store: "It's backordered with Laser Performance". What they don't know is that LP doesn't even have them.
    btw, Fogh Marine has 21! but international shipping was $35, so the money wasn't ever gonna let me get that one!
    Thanks for your help

    I went to the hardware store and got a piece of copper pipe and put a slight flange on one side. It works very welll so far, but my laser is a 71 . I mention it only if someone is reading this and given up on the bushings. Do read the other threads cited.

    Just a word of caution - the bushing has solved the leak problem but it is not the complete fix. The reason why the POS plastic bushings fail is 1) they are plastic and 2) one or more of the three attachment points between bottom and the aft bulkhead of the cockpit and the inside of the hull. I worked on a 1980 boat two years ago with a similar problem. a previous owner changed out the bushing and thought all was well. However, because there was only one rigid attachment point (i.e. the bronze bushing) the liner would move and flex in a chop. The result was that the hull started to crack around the bushing. Do not wait until you see cracks in your nice paint job. IMHO, you should really glass the after bulkhead to the inside of the hull.

    My laser doesn't have a plastic or brass bushing in the bailer hole and my boat takes on about 2 gallons of water every time I sail could this be the same problem with me

    We confirmed our problem by filling the boat with a few liters of water into the hull plug from a hose; closed the plug, and when we tippt it back to drain, the water poured liberally out of that bailer hole. It was nearly impossible to find a new brass bushing however. Above are a few places I checkt, had success with Kolius, and snatcht up their last. Where in Europe you'll find one, I cannot say.
    The new bushing solved our problem. You definitely need that plastic or brass bushing; obviously the latter is preferable.
