Reply To: Pre-war Mercury/Wizard gear cases

Louis, I have a number of questions now.

Is that spring holding the eccentric cam pin really necessary? Where could it go? Also, I don’t see the spring in the charts Bob posted in the tech section.

Of the 3 I have taken apart recently, none has the packing cup (part #64A) that is pictured in plate no. 2 of Bob’s “comet deluxe” general instructions manual below. Nor do I see that part in any subsequent charts (chart #8) of the gear case.

I have heard you mention before that we have to make a leather or cork seal for these early gear cases? Can you tell us more about those and show us where they would be installed and which particular models would require them? Do you know the dimension it should be?

Finally, the vaned rotax type impeller can only be used with the 3 slit type water pump housing, correct?

Thanks for any info you can provide.
Scott
