Hi Jarrod...Thank you for selecting the undersigned to reply to your question.

A 34 yr. old engine? Wow.

Chances are there could be a problem with the shift linkage or cable. Alternatively, the pinion gear may not be engaging for any number of reasons. Best you consult a reliable marine mechanic to do the trouble-shooting, and hopefully he will be able to locate parts that vintage of engine.

Safe Boating
