@rene - are you looking for vintage brochures? If you're looking for service manuals, you won't find them. Like many boat builders, Rinker didn't produce detailed service manuals. We all just find manuals for the components (engines, water heaters, battery chargers and so forth).

Anyway, I haven't been able to find catalogs for mine - as a '98, it's too old, apparently. You may want to check out https://www.greatlakesskipper.com/oem-parts-and-accessories/rinker-boats and Rinker Boat Parts | Replacement Parts For Rinker Boats (boatoutfitters.com) ... both sites seem to have a good supply of OEM parts.
Would love to see a pic of your boat...
