Ended up going with a JR DS8411 for the rudder.

I was going to mount my YS160 on the side but after installing a Hyde soft mount found that it puts the motor too far foreward to where I would have to hack up the cowl pretty bad. I went inverted and the cowl will just fit after cutting up to the cowls nose ring. Sent the side mount slimline muffler back in exchange for the inverted model and went for the smoke version this time just incase I get that itch, I could not find out how much more weight the smoke version adds, hopefully not much
