    2009 Sea Ray Sundancer 270 - with Arch
    Mercruiser 350 / 300hp Bravo 3 drive
    Hi there, just purchased a used 270 2009 Sundancer with a sunroof on the deck before the opening hatch. Every rain storm I am getting a ton of water in the cabin. Have pulled the hatch and resealed with marine butyl strip. Then put adhesive sealant behind that. Now still leaking and thinking it might be the skylight sunroof. Anyone have a similar issue? It may be that previous owner walked on skylight thus loosening the seal. There is very limited info on Sea Ray website. Any suggestions or anyone have any experience in dealing with similar situation. Thank you.

    Sea Ray's website won't have "fix it" information - just like Ford's site does not.

    I'm not quite sure exactly what you're saying... is this correct: You've resealed the non-opening skylight, but have not re-sealed the opening deck hatch. However, the leak "appears" to be coming from the skylight?

    Assuming yes...

    It only takes about an hour to reseal the deck hatch. But I think the next course of action is for you to spend some more time and find out exactly where the leak is coming in. The deck angles downwards, so while it's unlikely that the leak is showing up at the skylight but leaking in at the deck hatch, anything could be possible. Use a hose on the deck hatch... does water come in? Try the same on the skylight but tape over the deck hatch to avoid confusion.

    Sorry I was not more clear. I have resealed the deck hatch. I am inquiring about the non opening skylight. My deck hatch seems very tight. the skylight is behind the deck hatch heading towards the bow. Water would be running over it before it hits the deck hatch. But I will give the hose a shot. Still cold here so have to wait for that bluebird day. Thank you,

    I assume you meant "heading towards the stern"? :)

    The skylight is sealed to the deck and then there is caulk around the perimeter "gap".

    Is it loose at all. No idea how they attached it -- but maybe just with 4200? Is there some kind of frame? Bottom line, sounds like you need to rebed that skylight.
