I need some information on how your exhaust is designed to prevent a flooded generator. Our Northern Lights 5 KW generator is installed below the galley counter top sink area. The limited space down there has caused the generator to get hydro-locked, luckily no damage resulted. I think the only way to raise the exhaust hose out of the muffler is a loop up thru and down under the head vanity. What type of design do you have on your Manatee's ?
