I would start looking on sites like oldmercs.com or maxrules.com for old mercury parts

Curious, what is wrong with yours, or is it missing? If you still have yours but it is botched up, maybe you could have a machine shop pop one out. It couldn't be that expensive. I mean they are usually brass. :noidea:

You could probably get the whole carb for it on e-bay easier than finding a jet

Agreed here.------What is wrong with the carburetor parts now.------Or are there issues with the motor and as is common the " it must be the carburetor " syndrome is prevailing ?

Thanks for the info everyone. I need part #29. I tried to remove it and the end is kinda strip but can still use. I also need #31 I totally destroyed that one trying to remove and clean. Marineengine website they have part #31. I also considered finding another carb because i like to keep backups.

Another thing with this motor. I can not turn it from left to right. how can i get it to swivel? I have already grease the fittings do I need to add the torch to it?

You may have to pull the swivel/clamp assembly apart and replace the bushings or clear out the corrosion
