Wards Recoil Pawls.

[Tz9ccz23]

I see my recoil paws as attached by

a thin wire.  Is there a specific procedure and material to use to be most successful on a repair of this part of my motor.?  I have 74MG9021 Model.  Serial #117340.  Not sure HP of this motor.  It also has a variable propellor hub that I have not seen on the internet so far.  Looking for any help on these issues.

Here’s a few more pictures of the adjustable Prop.  Any help is appreciated.  Now on to my project making recoil pawl springs.

Well that prop is sure different than any adjustable pitch prop that I had ever seen. The usual adjustable prop the blades are movable to the hub, allowing the pitch to be changed, your blades are integral to the hub. My guess is that the entire hub is tilted on the shaft, there by effecting the blade angle to the line of the prop shaft. Try loosening the nut and see if the hub “wobbles” on the shaft.

Very cool and unusual…

Your prop it a Paul Bunyan Vari-Pitch from the Paul Bunyan bait co. Minneapolis, MN. They show up from time to time. Hunter sold this one on eBay last June for $30.00.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

Thanks for the help on my propellor, anyone got the decoder for my serial numbers ?

Model 74MG9021. Serial # 117340. Believe it’s a 1947 but not sure how to dissect the rest of it?

Thanks in advance!

Appreciate the details on the variable propellor.  Nice to have some understanding on that.  Thank You

I’ve heard of people using one of the thicker acoustic guitar strings for the spring wires. I’d go with maybe a heavy gauge “B” string. I don’t know why it wouldn’t work, and it would be cheap as well.

The way this starter works is the springs push the paws out and they catch in notches in the flywheel. When the motor starts centrifugal force pulls the paws in. If a spring is to strong the paw wont pull in and you’ll here it clicking on the notches of the flywheel as the motor runs. A friend and I tried to make some and we didn’t have the recommended guitar string. What we had was heaver and we could never get the tension right so the paws would pull in. From our experience I think these springs are hard to get just right.
