G'day i've got a peak26 and its a sweet little gasser,turns a 17x8 at 7600.put about 2 gallons (converted that in my head for the unmetric ) thru it and i couldn't be happier.It prop hangs the 72 inch extra at half throttle and pulls out vertically.a few older members at my club cant stop saying how good it pulls,all the us engines we get here are to heavy or over priced.
