The ball sometimes stays in the reel because the reel stops out of line with the catapult opening.
Fish Tales: reel doesn't release the ball
Cause: The polyurethane drive belt has taken a set after long storage and drags, or the motor coasts past the stop point over time.
Checks
- Check the belt for an oval set and the reel for free spinning.
Fix
- Fit a new belt; a pinball rubber ring also works well and grips better.
- Widen the ball release opening in the metal catapult with a rotary tool so alignment is less critical.
