Frequently Asked Questions
Q: Will this kit fit my 1990 Mercury 90 HP?
A: Yes. This kit is compatible with Mercury and Mariner 75-125 HP outboard engines from 1984 forward, including 1990 90 HP models.
Q: What are signs of a spun propeller hub?
A: Key symptoms: engine revs increase but boat speed doesn't, a burning rubber smell near the propeller, or the engine hits the rev limiter at lower-than-normal speeds. A spun hub means the propeller isn't gripping the driveshaft.
Q: Is this a complete propeller replacement?
A: No. This is a propeller hub/drivetrain service kit that addresses the internal hub components. It's designed to restore a propeller with a spun or worn hub rather than replacing the entire propeller.
Q: Can I install this myself?
A: Yes, with basic mechanical skills and common tools. You'll need a prop wrench to remove the propeller first. Many boaters perform this service at home; however, professional installation is recommended for those unfamiliar with marine drivetrain systems.
