Difference between these 4.5 props?

[sloopy]

part numbers 48 - 77716A1 and 48 - 63494A10 for a 4.5 single cylinder. They are both props but what are the differences? <br /><br />Also the 4.5 I am working has its propellor firmly corroded to the shaft, any sane ideas on how to get it off? I am going to use an insane one soon.... <br /><br />I am not posting this in the prop forum because it is not really a prop question, it is more of a part number and difference question. I am not asking anything about the pitch or diameter or how to get better hole shot. <br /><br />Thanks guys!

^bump. These are part numbers from Doug Russell Marine.

You can download MW comprehensive catalogue from: <br /> miwheel dot com/MIWheel/Catalog/default.asp <br /><br />It's in PDF format, it cross references merc part numbers and gives detailed specs.

I had a prop stuck to the shaft on a Merc 1250 a long time ago and was told to use a blow tourch on it. It really worked great, the props rubber center started to melt and actually pushed the prop off. Once it was off, I used a flywheel puller to get the rest off. Don't know if that will work for you though.<br /><br />craig

Sloopy, does the 4.5 have a reverse?<br /><br />If it does, you can leave the prop nut loose (install the cotter pin though) and run it hard in reverse.<br /><br />I've had several stuck props pop loose that way.

Yes it does have reverse. <br /><br />I still can't find the difference in the props.
