Review on 🔧 Enhanced Efficiency with Duo/Twin Prop Tool Kit: 3855516 Propeller Wrench for Volvo Penta D F Duoprop by Shug Quinn

The product does what you really need it to do – Remove the lock nut from the front propeller. A socket wrench that removes the first nut is fine - my experience is that the handle will bend and give slightly before my nut is lost. I ended up having to use the ratchet and socket I already had. He removed the patented nut, but had to use a long-handled screwdriver as the handle that came with it bent/bent again in the process.
