1. VIF 9 7/8 x 11 1/4-F Boat Propeller 664-45947-01-EL for Yamaha 10 Spline
This aluminum propeller earned the top spot because it balances everyday reliability with a remarkably low price point. If you need a straightforward fix for a dinged-up blade on your 10 spline shaft, I think this serves as the most sensible starting point.
Buyers consistently report that the installation process is refreshingly simple and matches factory tolerances closely. But I should note that stock aluminum options like this one will not give you the top-end speed gains you might see from a pricey stainless steel upgrade.
Buyers frequently mention that this propeller offers an exact fit for standard 10 spline Yamaha lower units.
Reviewers appreciate the straightforward installation process that gets boats back on the water quickly.
Users note that the aluminum construction provides a reliable budget-friendly alternative to OEM parts.

Choosing Between Them
The VIF 9 7/8 x 11 1/4-F takes the top spot as your most reliable replacement choice, but keep in mind that stock aluminum options offer limited performance gains compared to stainless steel upgrades. My top recommendation goes to the VIF 9 7/8 x 11 1/4-F for any boater who wants a budget replacement that performs dependably without breaking the bank.
And remember that matching your exact pitch and diameter remains crucial for engine health, because the wrong propeller geometry will destroy your fuel efficiency. Take your time verifying your shaft spline count before ordering any part to ensure a proper mechanical fit.
