I have a helix for a yamaha in my shop with PT# 7PT7 on it. It has no other markings. I would like to know the make and the specs of this helix. Hope someone can help with this problem. I belive it came off oa srx700.

If your in a hurry you can push the bushing out from the center. Sometimes the angles are under that. It's not a Bender or Hauck number. It might be a Max Perf. part number, if it is then most likely the numbers you want are under the bushing.
found that is is most likely a 44/34 and it is a Maxximum Doug

I Removed the bushing and found no numbers under the bushing.
Are you sure that it is a max doug 44/34
