Juergen,
Yes, you do need a cover plate. Now you need to determine which cover plate.
There were at least two different cover plates of different sizes.
I had an alternator on that pad and recently removed it. There was a cover on
that pad but in the building years, I have misplaced it. So I called Lockwood
Aviation to obtain a replacement cover. They had just removed that cover from
a new engine and send the cover and gasket to me free of charge. (Great folks
at Lockwood!) The new cover and gasket arrived but it didn't fit. Seems they
have changed the configuration of that pad sometime in the last 10 years.
Here is a picture of the new plate and gasket along with the alternator adaptor
plate that came off my engine:
I turned them over and added a ruler so you can get an idea of the sizes:
As near as I can determine, the old cover plates are no longer available.
If your engine uses the new, larger, cover plate, I'll be happy to send the new
plate and gasket to you or you can contact your local Rotax dealer to see if
he has one lying around that was removed from another engine.
If your engine is older, like mine, you can still check to see if an older plate
is available. If not, perhaps you can do as I did and make one up from aluminum
bar stock:
That's a piece of 1/4 in aluminum bar stock cut to shape and drilled using the
adaptor plate as a template. I also made up a thin silicone gasket to go
between
the plate and engine.
I hope this helps.
