For your consideration, here is a New Piranha Composite Propeller Part Center Hub, no. CH1A, part of the Hub Assembly MA3, A Style for use on Mercury, Mariner and Mercruiser. All items have never been used. The instruction sheet, grease packet, Piranha brochure and Piranha decal are also included. The Rear Cap, no. RCA would be the other part of this, but I don't have it. Items pictured are the actual items up for sale and come from a non-smoking household. (105.251e-2.7sp)
