Curious to see how others have accessed the holding tank on a Mainship 390 with a single engine to change the hoses. Mine is located in the center just to the portside of the lower helm. There is very limited access through the hatch under the lower helm and through the steps that lead down to...
Does anyone know which gasket fits in the channel in the hatch lids? I have a 2000 Mainship 390. All three hatch covers have solid smoked plexiglass hatches. There is a channel in the plexiglass where the gasket fits into.
Thanks
