Need a replacement engine for your Stinger equipment? This is a brand-new, genuine Kohler ZT740-3007 (Rehlko spec PA-ZT740-3007) 25 HP Confidant vertical-shaft engine with a 1-1/8" x 4-5/16" crankshaft — the engine spec used on Stinger machines.

Kohler Engines now operates as Rehlko; same engine, same factory, same part number. Ships new in the crate with the manufacturer's engine warranty.

Before you order: confirm fitment

  • Check the engine tag on your Stinger machine: it should read ZT740-3007 / PA-ZT740-3007 or an older spec this engine replaces (ZT710-3030, ZT730-3034, ZT730-3043, ZT740-3063, ZT740-3065).
  • Match crankshaft diameter and length, mounting pattern, PTO/clutch, fuel and wiring connections.
  • Not sure which engine your machine has? Call (646) 666-7225 with your machine model and serial number and we'll confirm the right spec.
