Default help with older Mercruiser

Hi everybody

During Covid, I acquired a Marieholm Concorde V8 with the intention of renovating it. I sailed it a bit initially, but then various issues arose, and since then, it has been sitting on the trailer waiting for some love.

One of the problems is that it's dripping some oil from the propeller. So, I suspect there's a leaky seal in the lower part of the drive.

Another issue is that the screw for the control/filling of oil in the drive is hopelessly stuck. I've tried WD40 and tapping on it, but nothing helps.

For starters, I need help identifying which drive it is. Can anyone assist with that? Otherwise, it will be difficult to find spare parts.

I need 2 more entries in order to upload pictures, so there will be 2 blank entries before the images.

Best regards
Mads from Denmark
