Any thoughts on what happened to this company -- or tips for
troubleshooting in particular the electronics. After some big rains
this year we did have some issues resulting from moisture that got
under the cover. Any other information resources out there on Ozark
boats?

Other than the engine and lights are there any electronics you need to T-Shoot?

Johnson has full parts diagrams on their web site, and you may be able to get original
owners manuals and factory service manuals there as well.
My '68 100 HP Johnson outboard came with manuals,
the service manual includes wiring diagrams, most parts are available from Johnson

The blower is for inboards or inboard/outboards, vents fumes before starting to prevent a fire hazard.
Perhaps your boat was originally equipped with an inboard.
