whats your Top End on 23s

[peterb]

I would guess that you could get somewhere between 46 and 48 mph with an ETC 250.

I am using Yamaha SWS props (21" pitch and 14 & 7/8 diameter). Also, I just moved the engines up 2 brackets.

I'm low 40's w/250 2s Yam., bracket, (probably mounted too low) w/17 Yam. ss prop., 1/2 tank, calm, best conditions, etc. I will have more HP at re-power, for what that's worth....
