M601-B & M601-D OVERHAUL

Expired Walter GE M601-B's and M601-D's are available for a low acquisition cost; in some parts, they are abundant - but not for without reason.  The cost to replenish a TBO on these turboprop engines is substantial and often makes no sense economically.

However, if you're building an experimental turboprop aircraft and are looking for a sensibly priced engine with at least an 750hr TBO, then read on.


An increasing number of new Experimental Turboprop aircraft examples are being built in the US; which is great for General Aviation and homebuilders.
