Ross, either the 21" 2-blade bronze or 21" Ballistic should run well at 5,000 RPM. I forgot if you have a tach or not. If not, you should get one installed or else use a hand held one just for testing.
Yup, I have a tach.

Finished the e-bay purchased 21" cupped 2-blade bronze with before and after pictures. Finished with props, now to sharpen (but not polish) lawn mower blades. Prop collection consists of 5 bronze, 3 stainless steel, and 2 aluminum (came with the 1988 115 HP Merc).

I'm picking up a 23p Raker tomorrow for cheap.  I'm really anxious to try it on the 19...I think it'll be too much, but for $50...why not.

Here we go again. Another prop to restore. Purchased from the original owner. Never reworked. Prop sat for 20 years collecting dust. It is a small eared chopper, 14 dimeter x 22" pitch, number 48-75770A-4 22. Will post pictures after cleanup is done. This is the 10th prop to the collection and the last. Joke to my understanding wife is that the prop collection is my retirement fund. Will be a prop to try if the motor is elevated on the transom 1-1/2 to 2"

A Raker for $50? :o  That's a heck of a find since they run about $350 to $550 depending upon age and condition.  I tried a 13 1/2 x 21 Raker on my 1977 115 Evinrude (CVX 16) and I dropped about 3 - 5 mph. I want to try the 19" next time. That is on hell of a smooth prop.

Yeah!! Now yer talkin' David! Heh heh

Looks kinda like an OMC SRX but what's up with the blades sticking in front of the hub. Maybe it's an optical illusion but just looks a lil weird from where I'm sitting?

Doug, those are weed cutters. Maybe they have a purpose, but I do not intend to travel through weeds. Could be that while racing weeds would otherwise wrap themselves around the prop were not for these sharp pieces of metal that cut them into small pieces.

Aha! Now I understand. I avoid traveling through weeds too. Well, 'less it's really good weed ...  Truth be known I'd like to hear more about this "racing weed"?!

Seriously I don't see how those cutters could do much if any weed choppin' on a small hub prop. I do see where they might could help if'n ya got tangled up in some monofiliment.

Interesting wheel Dave. I'm expecting once you work your magic on it it'll be bada$$.

Carry on!

Beautiful work David! Too nice to submerge.

After hours of working to remove scratches, here is what the prop looks like. It is meant to run with the motor off the transom. Prop is Mercury chopper 14" diameter x 22" pitch exhaust over the hub. Upon takeoff, the prop will rev up and then bite and fly at a certain point in time per the former owner. Stainless is harder than bronze to work on. Used combination of discs and sheets of sandpaper from 240, 320, 400, 600, 800, to 1500 and then to Mothers Alum and Alloy and Flitz. Top picture is the before and next three are the after.

What do you use for sanding? Do it all by hand?

Ya it takes a little finesse to run one of those choppers. But once you figure it out the mid-range acceleration is breathtaking. Oughta pick up some top end too.

Now all's ya need's a jack plate David so you can take full advantage of all them props? Heh heh

Nice job on the clean up btw. Looks real purty.

Jason, to start, I use a 120 grit sanding disc on a 4 1/2" rubber pad attached to a power drill to get off the deep scratchs and nicks on the blades. May even use a file. After that, it is 240 grit wet or dry sheet 11"  x  8" sandpaper torn into quarters and then folded to be used by hand, and then up the scale, all by hand, to 320, 400, 600, 800, and 1500 grit. At that point, the surface is smooth enough for the buffing compounds on a 3" cloth buffing wheel on a power drill can take over - buffing rouge, Mothers Mag and Aluminum Polish, and Flitz. After the buffing, then back to the areas that need more sanding and buffing.

This prop had scratches all over the blades, as you can see from the before pictures. Have about 5 to 6 hours of labor in it so far. Really a labor of love. I only do it about an hour or two per night.  

With stainless, you have to hand sand to about 1500 grit before the machine buffing, whereas the bronze props only have to go to about 400 or 600 grit before the machine buffing polishes and erases the little scratchs from the sandpaper.  

Doug, thought about a jackplate, but the ride glide steering cable comes out of a hole on the drivers side of the boat and I do not know if it could make the bend with the motor set back any further.

This bronze Mercury Quicksilver 19" pitch prop purchased on e-bay under false statements as to condition but seller refunded money 100% and said I could keep the prop. It needs a new rubber hub, $60 (old hub dry and cracked) and one blade missing some material. Will post pictures of the polishing process - my outpatient occupational therapy. Might become part of the Hard Luck Trophy.

Picture of the six bronze props - four 21" pitch, one 19" pitch, and one 23" pitch. The 19" (farthest away) is in the process of being buffed out. Note the difference in hub positions in the middle picture. The rubber hubs needs to be moved/pressed so that the washers on both ends of the hub fit into and match the hub recession. Craig at work will use a hydraulic press and cutting machine tool to fit the components.
