262pequa

Hi. I recently purchased a 2000 262 cruiser. Excellent boat, really enjoying it. A few minor problems though that I would like to address. The portlights over the galley are leaking a bit and I am wondering if there is a way to replace the gasket that seals them. If not is there a replacement available? Also, the helm seat is broken and I am wondering is there is a suitable replacement available somewhere. Thanks for the help
