Need a Float for the Mikuni Japan carb

I have a yamaha p65, no- 821428 outboard, possibly a 3.5hp. I'm after a float for the Mikuni Japan carb. Can you help please? Would a motorbike float be the same? Thanks, Simon.

I'm not familiar with that motor. Mariner had a 3.5hp that may have been a Yamaha motor, look at this diagram to see if thats it Mercury Mariner Parts 3.5 642-23740 AND BELOW CARBURETOR Diagram

The carb is no longer available but there may still be some carb parts around.
