Have a G1 300 on my '75 23cc -no bracket. Runs spot on with a 15 3/8 X 18 Rebel. Tops out at 50 mph @ 6100 with a light load. Cruises 30 mph @ 4000 with a full tank (110 gal).

I hear the new BRP RX4 prop is pretty sweet. The web site says it's matched to the G2 power curve, however from what I've been told it works as well on the G1.
