The adjustable kicker bracket was manufactured by Spar marine in Vancouver. I had a 9.9 Merc on it on my old Hourston. The composite plate that the OB clamps to was removed and used on a fixed mount. But its easy enough to replace with plywood or plastic from Industrial Paints and Plastic. $25 OBO
Item two is a older brass prop , Looks like it came off an older sterndrive. 10"/11" RHR. Dont know the pitch. Would make a nice wall hanger if it was polished up.
PM if interested.
