is the ball removable without unscrewing it? what it the distance between screws on center?

the housing is 2 pieces. you can remove the outer portion that holds the ball. it can be removed by removing 2 small retaining screws and the outer part twists to the left to unlock and remove it from the stern mounted base. the base mounting screws are center to center are 2-7/16"

Hello! Quick question... My boat transom drain tubes measure 1 3/8". Is the scupper seal ball opening same size, or wider, than the 1 3/8" hole?

The seal ball seals to the base of the seal-ball scupper and not to your drain holes.. I have been using these for several years and they work great..

Will it fit a Sea-Doo Speedster 150?

It should, measure flange to make sure. OEM standard
