Hello everyone!
I recently acquired a webra engine from a guy and I do not know anything about this one. It looks like it is set up for boats(?) I fly planes and was wondering what model this engine is and if someone might know where I can get the proper hub and/or muffler for this powerplant. The muffler holes are plugged so I imagine it requires a muffler with a strap. Any information on this engine is appreciated. I also do not have a project for this engine and would consider selling it to someone who may be looking for this kind of engine. The engine has GREAT compression and it looks like it has little or no run time on it. Here is a picture of the beast!

Thanks for your help!
