Have you looked into marine pans? Most of them are full sump with some type of baffles and doors. Make sure the pan is orientated for the application, a v-drive pan is orientated for the engine facing backwards. [flywheel facing forward] so you would probability use the Jet boat pan as it is set up for flywheel towards the rear of the boat and baffled/doored acordingly. Try Dooley, Milodon, Aviad[sp] or Moroso. There is another excellent pan available by an ex Aviad employee who's name escapes me right now but he makes a damn fine pan....CRS, ya know.
