Frequently Asked Questions
Will it fit a Yamaha F6 four-stroke?
Do not assume so. The verified core fitment is selected 6/8 HP two-stroke engines.
Is a gasket or key included?
The listing is for one impeller; other pump parts are not included unless shown.
Can dimensions alone confirm fit?
No. Match OEM number, key design, width and vane count as well.
What can damage an impeller?
Dry running, sand or silt, long storage with set vanes and a scored housing can reduce output.
Installation note: Never start the engine without cooling water. Install with the vanes folded in the normal direction of shaft rotation and inspect the housing, wear plate, key and seals before reassembly.
