I found bearings from an electrical motor and industral supply company, they are the 1 1/8 shaft bearing I used in my 75 Whip, the brand is an AMI Bearings Inc. #KH206-18. Hope this will help you out. Carl
realize this is an old post, but things move kinda slow in the Whip world!
thanks for posting this bearing number, I was stumped looking for a replacement for my 75 340 Whip. Are they still holding up?
