Updates 2026-05-09 from Yamaha official propeller guide (page 11 Mark Chart)
The 2.50" gearcase + 8 spline platform is shared by two Yamaha mark families
- Mark R: T8, T9.9 (high-thrust series, 11-3/4" diameter, large pitches 5-3/4 to 12-1/4)similar for R series.
- Mark J: 9.9-F20 standard (smaller diameter 9-1/4 to 9-3/4", pitches 6-1/2 to 12)Mark Letter Advisory: Yamaha mark letters (A, BS, B, BA, N, R, J, F, G, K/KL, M/T, X/XL) are Yamaha OEM identifiers stamped on Yamaha-branded propellers. They help identify a Yamaha prop's gearcase family. Fitment, however, is determined by gearcase diameter + spline count + hub style, NOT the mark letter. Aftermarket props (Solas, Michigan Wheel, Powertech, Quicksilver) and some unmarked Yamaha props will fit identically when those three match. If James says he has a prop marked G, this block is likely the right reference; if the next prop is unmarked but has the same gearcase + spline, it still fits.
Both use identical hardware (2.50" gearcase + 8 spline + pressed-in hub) and are interchangeable from a hub-fit perspective. The block fitment correctly covers both.
