I have a VR45 that has clamp bracket drilled to the rear of stock hole by 1 3/4". I believe motor was never raced and sold new to be installed on a large family cruiser. The prop that came on the motor was a Michigan RC 11 which I found listed in an old Michigan catalog as a 10 3/8" X 14" three bladed prop used on Large Family Cruisers. Does anyone else have a VR45 with this hole pattern?
