Im mounting an above said outboard to my Sidewinder resto. There is a CMC PT130 going between the outboard and transom. Ive got the new bolts for the CMC to the transom. But I went to measure for size and length for the outboard to CMC bolts. They look to be about 3/8 dia bolts....

Is this correct? Or are you guys using a different size...

That motor uses 2 3/8" carriage bolts. Make sure the transom clamp is tight as well.

Thanks for the tip. I figured it out after finding a new stainless 3/8 bolt at work and brought it home. Mine actually has 4 bolts plus the transom clamps.
