Last fall I bought a 28ft. 1979 carver mariner with twin 305s. Really like the mariner style with the large bridge. The two annoying problems to date are a smell from the area near the holding tank. The previous owner said the holding tank leaked. He installed a new 25 gallon holding tank with a macerator pump pulling from the head it has sewage grade hose & appears to be vented correctly? The other non structural problem is dry rot above the windows under the bridge enclosure. Any suggestions for repair it's about a 3/4 wide by 1 1/2 deep area 9 ft. long that the aluminu trim pc. screws into. The area in question is above & over hangs the side windows. I can't shove a new pc. of wood in the slot because their are screws in the way.
