Help..! Need to ID a small outboard motor

[DaveEsch]

Regarding the water pump…

I’m looking at what I believe to be the impeller and from the illustrated parts breakdown it looks as if it has one blade/wiper… is this correct and is it a rubber part or a metallic part?

Any recommendations regarding a source for the points and condenser, impeller?

463-5100 is what many of us call a “wobbler” impeller, properly called a “rotor”.  They are pretty reliable.  Their main enemy is grease leaking out from the gearcase, which causes the rubber rotor to swell.  That, and sandy water which causes wear of the rotor and aluminum cavity it wobbles in.

The points/breaker and condenser in the ignition circuit…

is it pretty vanilla with regards to the 1970’s era ignition condenser size?

I have not taken it apart yet but wanted to get the scoop on this…
thanks in advance

It’s a Wico Magneto with an unusual condensor and points assembly.  The Points connect directly to the condensor.  Very reliable mag in my experience esp[ecially if it has the orange shellac looking coil.  Just polish up the points and you will probably be OK.

Thank you for the pic… gives me a idea of what to expect…

side note:

I was all giddy when I removed the cover on the lower unit and found it in tip-top shape…

I then removed the nuts securing the impeller/drive shaft assembly…

the first thing I noticed was a cam shaped lobe and the rubber impeller not bonded to it.

would I be correct in assuming the cam element is on a spline and tapping it off is the removal process?

I have made the assumption that the impeller is all jacked up because it is not bonded to the metal lobe…

Looks good to me.  Turn the driveshaft with the impeller on the lobe and you will see the motion it creates.

The rubber wobbler / impeller is not suppose to be bonded to the eccentric cam.
There’s probably no good reason to remove the cam off of the driveshaft. I’m
guessing that the cam is pressed onto the driveshaft, but I’d have to look at mine
to be sure.
The last two motors like yours that I worked on had a lot of wear in the
cavitation plate that the wobbler rides on, from grit and sand no doubt.
The first motor, I sanded down the cavitation plate for a new wear surface,
the last one I flipped over, but I had to drill a new hole for the pump discharge,
and plug the old hole. Hopefully that works out, as I’m putting it back together
today.

Prepare to be boarded!

Anyone printing impellers?

need a Scott Atwater 3.6 HP Wobbler

[DaveEsch]

Unfortunately I could not find a source for the wobbler… knowing the general age of the motor and the general history this makes sense… with that said I suspect reverse engineering/printing the part is the next best option or identifying a source

the plate that interfaces with the wobbler looks as if someone fabricated a new one from plate stock… I suspect the original was a hot mess

Thoughts?

seems like a solid motor… source for new old stock is a bit difficult

It’s hard to tell from your photo, but your wobbler doesn’t look that bad.
Is it still a snug fit on the cam?

Prepare to be boarded!
