About this part

This is the O.S. Max .46AXII ABL Airplane Engine with the E-3071 Muffler. This engine features an Advanced Bi-Metallic Liner that uses a double layer of plating material rather than one thick layer. This helps the metal to bond to the cylinder and increases durability. Also, the plating process is more consistent, resulting in a more precise fit between the piston and sleeve for better compression and longer life. The E-3071 side exhaust Power Box muffler features a squared-off shape, enabling the Power Box it to fit into a variety of cowls avoiding the frustrations of compatibility issues.

  • Advanced Bi-Metallic Liner

Larry HyattVerified owneron O.S. Max .46AXII ABL Airplane Engine w/Muffler

I used to buy from Tower, but I have bought more from AMAIN as of late, AMAIN tries to get my orders shipped fast and most of the time has what I order, I don.t like it when it says in stock and after I order it is out of stock, I don't order anything on back order....

Lowest prices on the web, too many things are getting more expensive.
