O&R Compact R/C Boat Engine

[1olddog 3]

I just bought an O&R that was from an r/c boat ,probably the Octura White Heat V. It has an eight pipe exhaust for a boat.I've cleaned it up and ordered a pull starter knob for it.The O&R 1 HP decal is worn off and also the label on the pull starter. Is there anyone that makes decals for vintage motors. It has model II on it but looks like a B was stamped over it.There's also an A stamped over to the right of the model number.On the other side of the engine is stamped 014811. There may be either a B or an 8 at the beginning of number.Don't know what I'll do with it as it's not fast enough for my r/c boats.May just sell it to fund another project.Here's a pic of the boat it was probably in.

It looks like a Model B with an X stamped over it to me (to convert it to a Model A), a Model B has a base mount gas tank, a Model A would have a standard round gas tank that could be fitted anywhere.

Serial #014811 would date from somewhere between late 1961 to early 1962, sorry I can't give a more accurate date for these earlier engines, after June 1967 they had the date coded into the serial number.

 

The engine is a 3/4HP version, it would not had a decal for this as no other versions were available at the time this was made.

These are the decals it would have had (from engine #014035);

 

The V8 style exhaust was supplied by Octura Models, the 60° version is for the White Heat V and the 90° version is for the White Heat X.

This is the correct starter knob for your engine;

factory,thanks for the info on the engine.I was just guessing on the hp.I was thinking that because it was in a boat it would have the greater hp.The White Heat boats with these engine weren't very fast for todays standards,but back then I suppose they were the fastest available.They were probably lucky to achieve 30 mph.A stock Homelite propped correctly will get that much and I have a full modded 25 cc Homelite that was at 54.7 mph on a GPS and that's fast for that engine.I'm into old woodworking and metal working machines and some before 1938 had no model numbers,just a name.I'm a member of OWWM http://www.owwm.org/index.php?sid=646df6f82b1017bee8d02919f050377d and will have to see if the O&R tools are on the forum or if they qualify to be on there as long as they're American made and over 20 yrs old and are either wood or metal working as a circular saw,sander or drill

I have that starter on it's way.

I got the new pull start knob today and put it on and also fixed a crack in the ignition wire with Performix Liquid Electrical Tape,so no spark would arc from the wire to the metal.

[1olddog 3]

What spark plug does this engine take ? The one that's in it is a Champion UY-6 and is one that the top cap screws on.There wasn't a cap on it but I found one off an old sparkplug.Need one that has a removable screw on cap.

The Champion UY6 is the correct spark plug.

The modern versions of the Champion spark-plugs used for the O&R's tend to not have the removable screw fixing for the HT lead that the originals did, they should really give them a different part number as they aren't the same. I first found this with the CJ8 used for the later engines with the 14mm hole in the cylinder, only bought NOS of the other types after that.

I want to paint the recoil housing on my engine and need to get the recoil spool and spring out. I visited the below thread but it doesn't tell how he got it out.What's holding it in ?I tried prying it out but didn't want to put too much pressure and maybe break something.I'd also like to replace the rope while it's apart. How do you get the spring retainer clip out without breaking the little ears off ? Also is there a favorite spray can of red,made by what manufacturer ?

I gave up on those little spring retainers. They get removed and don't go back on and I even have a bunch of NOS clips. They are a real PITA to get back in.

To remove the spool, don't pry on the spool or will get bent. Grab one of those spokes close to the center with your fingers or pliers and pull up as you rotate the spool back and forth an 1/8th to a 1/4 turn each way. You will have to "work it off" but you should see it moving up off the bearing cup. Re-install the same way but pushing down on the center with your thumb.

 

Same process for the newer type with a retaining clip but the clip needs to be released from the groove first

[1olddog 3]

Thanks ,I'll give it a try .

[1olddog 3]

Well I got the recoil apart without bending or breaking anything following Wallfish's instructions. I even got the retainer out by heating it a little with my little butane torch and then bent the ears back. I had to tap on it with a screw driver and it popped out and flew somewhere.Oh well I guess I don't really need it.I'll have to check the length of the rope and get a piece at a local hardware that has all kinds of stuff for mowers and hand held power equipment.What's a spray can red that is close to the O&R red.I got the pull starter decal and the bird one from Ebay ?

I've found this Ace Hardware Banner Red to be a decent match, especially for the older style engines. Search in the O&R section for a Chip-A-Saw restoration and you’ll see what it looks like on the recoil cover.

@1olddog I managed to retrieve the Model J at the weekend and as it was nice & sunny I took some good pictures outside. It has the correct decals that would have been on your engine (note: there is no "stop" decal).

If you still want better pictures I can email them to you.

Thanks factory.Those pics are great.I'd like to get some made locally as the ones off ebay are expensive.

I've gotten the shroud stripped down to the bare metal and I'm ready for the next step.I have the ACE paint you recommended.

Did you strip yours down to bare metal or just scuff up the old paint ? I know the paint says paint + primer,but would it be better to use an actual primer on the bare metal then use the paint ? My flash wouldn't go off for some reason.

[CNew 404]

I stripped to bare metal and used a base primer. I don’t think the paint+primers work all that great by themselves unless maybe you’re touching up a painted surface that is still in good shape.

[1olddog 3]

Well a couple of days ago I got all the old paint stripped off the shroud using Dumont Peel Away 6. I got it primer yesterday and today I painted the Ace Hardware Banner Red to it. It's really glossy,even better in person. I might clearcoat it,but not sure. I need to see if a local hardware has the small pull starter rope and then put the pull starter back together. Probably going to be fun and then on to putting the new decals on.I'd like to find or make a soup can type fuel tank for it .If all else fails I could get a round r/c airplane fuel tank,if I can find one big enough. I may even try starting it after all is done.

[CNew 404]

Very nice, that looks great!  FYI, Stens makes an aftermarket rope that looks really good and is the right size.

 

[1olddog 3]

Thanks,I think the hardware sells Stens products.

[CNew 404]

I think there is also a NOS O&R rope on eBay...
