1951 10 HP Johnson QD-10

[tbfosback]

I am working on this motor for a friend. The top cylinder has 65lbs compression and the bottom has 70lbs. It needs the carb rebuilt and the starter return spring. I have been unable to find any parts. I have only found 1954 and newer parts. Any ideas? Is this motor even worth it?

So a couple of questions...<br /><br /> 1) When was the last time the motor was started? Do you know?<br /><br /> 2) Do you know when the last maintenance was done on it?<br /><br /> 3) Did it run well the last time it was started?

Evidently, Sierra doesn't make a carb kit for that. Check here:<br />vintageoutboard.com<br />tcoutboard.com<br />americanoutboard.com

I have no idea about the history of this motor. I am pretty sure that it ran well the last time that it was started. But I believe that it has been a few years.

This may help you quite a bit:<br /> http://users2.ev1.net/~rainbowchaser/manuals/qd/qdr.html <br /><br />A lot of very old engines are neglected by Sierra and to a degree BRP. But with the original part numbers in hand you can figure out the modern ones. Sites like ishopmarine.com will provide the latest part number for older ones.<br /><br />Unfortunately, the rewind spring is listed under the old part number system, and I have no conversion table. But I'm pretty certain (I have a note that indicates) it's #395460 which sells both OEM and aftermarket for under $10.

I believe that a QD-10 is a 1949 model motor.<br /><br />The carb system was an odd-ball, only used for a couple of years. I think it was in 1953 that they used the carb design that you can still by repair kits for from the factory. Not bad still getting parts for a 53 year old motor.
