I/O Performance Advise

[Ripcurl]

Thanks for the replies...

Regarding diameter, I can only go up to 15 3/4... maybe 16 with the Bravo One sterndrive.

On pitch / other props I've tried, here's the history:
- Boat came with a 24P Bravo that had been altered somehow... looked like diameter was reduced and some cup was added... performance was slightly better but RPMs were hitting redline at 3750; yanmar spec is 3550 max propped rpm.
- I strapped a 24P stock on and lost ~5mph... RPMs still hitting redline
- Moved to 26P stock... slight increase in top-end, RPM's at 3650 / 3550 with light / heavy load, respectively so still need to bring down ~100rpm. Further, boat is a pig getting over hump
