Core drill hole where drain is larger than drain plug assembly. Glass fill the hole. Re drill smaller hole for drain. Fix Drain into the now glass surrounding, this will prevent water ingress into the plywood.
so the SikaFlex will stop the ingress of water from outside the boat hull, but water inside the boat will still be able to soak the plywood transom. No sealant on the inside??
No need to seal the inside as we are just preventing water ingress so we don't sink the boat LOL! The inside of the hull is coated in fibreglass so should be fine, no exposed plywood, other than in the plughole. The plug-holes are normally created during the manufacturing process so they too should be coated in either fibreglass and/or gel coating. If not, well the aim is not to get much water in the hull. Once you're out of the water and back home, keep the plugs removed and allow the transom and hull to dry out.
Agreed as others glass in the hole. You could have at least run the calking in the hole with a glove and let dry before adding plug outfit... lucky for me my Nordica is all fiberglass.
Why so many bung holes? Surely just 1 at the lowest point is adequate? Also what protects the inside of the transom from water isnide the boat soaking from the other side of the hole inside the boat? (great video though, thanks!). EDit: Great work on keeping your hands sooo clean, I can never manage to do that.
Hey, great comment. The hull in my boat is divided in two sections with the internal stringers. So 1 hole for each section. These are the two middle plug holes. The two outer plug holes empty water out from the fuel tank bay and any that collects on the floor. The inside of the hull should be completely coated in fibre glass, there should be no exposed ply wood soaking in water - you hope. Hence, why you leave the plugs off when the boat is stored for long periods, allows air flow through the hull.

Great advice, thanks.
What siez of screw r u using
Thanks for sharing, most informative. I was going to use silicone until I watched your video.
How did the boat go on the water after This video? How many litres come out after this fix up? Did you notice improvement?
For sure, not a drop of water came in.
Where did you purchase that style plug?
hey, sorry didn't see your comment... Just at out local fish n takel shop. Try your local boating shop.

The inside thru hull will continue to absorb moisture from the bilge area and rot out that transom. Way to many drain holes
fantastic info thank you very much

Rainwater is what usually rots out boats, cover the boat and have it up leaning towards the drain plugs on the trailer.
What grit sandpaper should we use?
120 grit
Isn't that overkill with all the holes in your boat? Why do many brotha?
each hole drains a different section of the hull and subfloor. Haines obviously had a reason for the 4 plugs. Not my design.
Itu dimana belinya dan berapa harganya.....

@@dgaltieri Thanks a lot for your info.
I HAVE NEVER HAD A PROBLEM WITH 100% WATERPROOF SILICONE USE WHAT YOU FEEL YOU ARE COMFORTABLE WITH.
Using the dremel has exposed your transom timber to water, this will rot the transom.
