Our Autoprop™ APA Adaptors.

Our APA adaptor for an autoprop™ feathering propeller is shown on the left  and on the right it is shown with its cone zinc anode attached by a central fastner. 

 The picture below left shows the APA adaptor attached to a typical autoprop™ feathering propeller.  The photo on the right shows the APA adaptor with zinc anode attached to the propeller by its central fastner.

The APA Adaptor’s are designed to match the standard hole and screw patterns of the autoprop™ feathering propellers.  This makes no modification of the propeller necessary to attach the APA adaptor, just line up the attachment holes, insert and tighten the supplied screws.

All of our SMT, Inc. Propeller Adaptors are made of high quality marine alloy and were developed over many years of in-water marine corrosion control.

 To order:

First determine which size of anode your propeller uses

by locating the size designation(H5 or H6) on the interior of the original zinc. 

Then match this measurement with one of the APA adaptors (H5 or H6).

Call (Janice @253-307-3360) or email SMT, Inc at smt@smtinc.net

and order the APA Adaptor that is matches the anode .
