Jeanneau Poker 28ft - Teak Deck Fix or Remove?

[fgcity]

The Jeanneau Poker i got came with a Teak deck which was laid out by the previous owner and i suppose hasn't been cared for for at least 5 years, on the Fiberglass boat. I am not sure if it was like this from factory but from all the images i have seen of the Poker it doesn't have it. My concern is that the screws which are in some cases poking from the other side within the interior will leak when winter comes. I was considering removing the teak and just repainting the boat deck. The wife says it looks better with the wood but i am the one who has to make sure it is watertight on the deck.

I can see in some places the actual wood is a bit swollen where there are handles on the hatches as well as some light cracks on the edges of the seat. I am not sure what is under the wood nor how well it is sealed.

I was thinking of removing every single screw and adding some caulking and re-screwing to seal it but i don't know if the fiberglass is cracked anywhere or in general what the condition is underneath.

Overall it looks descent except for the caulking needing to be replaced and the wood sanded and perhaps some oil laid over it.

My question is, would you guys suggest i rip it off and seal the deck properly as well as paint it to its white finish? The teak isn't all that new and although i like it, i wouldn't want my interior to be destroyed after the first rain.
