SX/SXi/SXi Pro Installing impeller KE-CD 9/15 Solas 750 Concord

[f1r3sh1p]

The Solas 9/15 impeller that I bought new is up to 1 mm too large in diameter to fit the pump housing.
It is advertised to fit my '97 750 SXI (year based on hull id) and I wonder if I should either grind the impeller edges, sandpaper the inside of the pump until it fits or just return it.

Finally got things sorted.

Unless you have professional tools, don't try to expand the pump housing. I instead used a flat sander to carefully sand off the excess from the prop blades. Make sure to mark well how much to be taken off.

As a note, when pulling old impeller the engine/driveshaft coupling got disconnected. I only noticed this when trying to reinstall the pump with new impeller.
This is obvious if driveshaft spins freely. Lucky the engine does not need to be removed to fix this.
