Lawn Boy engine swap

Posted by dcrso none (My Page) on

I was thinking of putting a 2 cycle 6.5 duraforce engine on a Lawn Boy 10515 Gold Pro mower deck. Mower had a 4 3/4 F-series engine orginally. Does anyone know what all I would need to change to make this swap work?

I'll give this a shot. The duraforce engine is designed with an above deck exhaust but the exhaust flow passes through a transfer pipe under the deck and up into the muffler. also, the engine mounting plate, looking at the parts viewer, looks different. I own both of these types of mower but never thought about a sweap.

RE: Lawn Boy engine swap

the engines' exhaust ports are shaped different. The duraforce port is also larger. Will not bolt up. You should be able to find another junk mower with an F engine.
