Fitting transom bung

[gtflash]

Im tired of the boat filling up when the battery dies like a giant bath tub.

Ive got a bung i bought last year in the picture but never got around to fitting it

How do I fit it. Drilling and sealing transom up! Seems lots of people have donw in but i not found a definative answer.

Thanks GT

1" holesaw to cut the hole out, brush some activated GRP resin to seal the exposed ply of the transom, when dry, apply some sikaflex (or silicone will probably do the job ok) around the cut edge of the hole and shove it in there, twisting to & fro to give a good seal in the sikaflex/silicone. A couple of pilot holes for the two A4 csk screws which secure it in place.

Check the thickness of your planing pad to decide how high up from the base of the pad to drill the hole.

Normal silicone caulk tends to degrade with long exposure to water. Make sure the sealant you use is rated for underwater use.

If the boats been built properly, you won't have ply in that area!

It has been known though, even in some 'proper' ones!
