At annual inspection I found propeller track was out of spec. Contact was taken with Helices E-props, and than propeller was sent to France for inspection. When propeller returns 3 weeks later, the carbon-fiber hub was replaced, and a 5mm thermic spacer was added. In order to reduce heat transfer from engine to hub. Prop mounted, pitch adjusted, torqued to 28Nm, and tracking rechecked. OK.
