I can't relate this prop to any listings I've found on the net. It came with my 31 Commander Sedan powered with 327Qs. The only markings on it are 4620C. Any ideas ? J.

You could give Johnny's Propeller Repair in Detroit a call. They're the experts. 313-885-7446

I have a '69 Commander, 31' with 15x17 props, 1 1/4" shafts, 327Q's. Just looked at my old ones. They don't have that number.

Are there any numbers on the other side?

No numbers anywhere other than 4620C. It does measure to 14 inch diameter,and RH rotation of course. J.

If no one on the forum can help, I'd call Johhny's.

According to the numbers I found that would be a 25x33 1.75” shaft. Unless you’re running some serious power I don’t think that right lol

That number is a chris craft number. There should be a plate under the engine hatch that will have the prop numbers on it, if it matches it then it is the original prop. If not it is just a spare that someone put in there. I know that somewhere there is a list of Chris Craft numbers that will tell you what the pitch and diameter is. My 31 sedan fly bridge came with 15x15 round bladed props. I pitched them up to 15x17 and seemed to work very well. I have since put on 15x16 with super cup and has been magic. If yours is 14" diameter it may have been damaged and shaved down. Dave

name that prop!  According to my complete Giant book of Chris Craft service bulletins a 1969 31CC with the Q's ahould have 15X17 screws, part# 12.13-01024  and   12.13-01025    4620C does not compute even in the pages with chris four letter numbers on the props.

The data plate has only the hull number on it. Prop is definitely 14 inch diameter by measuring from shaft C/L to outmost edge of a blade, indicates 7 inches. J.

Thanks Bob ! That is very useful information.

. I called the prop expert Johnny. He has no clue to who made it or what its spec are. I think I will frame it for display as " Mystery Prop ". J.
The image below illustrates the prop hub of the forward side towards engine. It has obviously been persuaded with a BFH at some point. I'm now thinking the prop data stamping may have been here and is now vanquished to obscurity. Yep, wall hanger. J

do you have a local prop shop that can measure it for you? most of our local shops wouldn't even charge you to identify a prop
