I also I found a number on the engine mounting frame, looks like 80087 12, does this help?

Thanks for that, I will have a good look (on the correct side) tomorrow!

Engine number location:
Plus two other places to look, the front projection in the bottom of the sump and the horizontal top surface of the generator bracket facing, see pics.

In addition it is often on the generator bracket itself and it will also be on the oil pump body, this is the unit projecting downwards from the back-end of the sump with a rusty 2″ pipe fitting in it.

Hi Pete,

I’ve checked the front port side engine foot, but its heavily corroded. Thank you for the pictures, I will check the other locations tomorrow.

Thanks again,

Walter.
